General Information

Cable tray systems are designed for the support of cables, electrical equipment and/or communication system installations. Where necessary, cable tray systems may be used for the segregation of cables. These systems are designed for use as supports for cables and not as enclosures giving full mechanical protection. They are not intended to be used as walk ways or support for people as this can cause personal injury and also damage the system and any installed cables. Cable tray systems shall be manufactured in accordance with BS EN 61537.

1.1 Application of equipment

Cable tray is used in a variety of both internal and external projects and applications. Cable trays are designed to provide support to any cables which may be installed upon them but as they are not fully enclosed they do not offer complete mechanical and environmental protection. Therefore unsheathed, single insulated power cables should not be installed on cable trays. Cables installed on cable trays should have some form of mechanical protection, such as PVC sheathing or a steel wire armour (SWA). On many occasions cable tray is installed where it will only ever carry a light cable load and its main function is to physically secure and protect its content. Ideal applications for this type of installation may be commercial premises such as warehousing. On other occasions the cable trays may be more heavily loaded, perhaps with heavy duty armoured cables. Installations such as these could be external and might include processing plants, power generation plants and marine applications.

1.2 Description

A system used for cable support consisting of a choice of four depths of side wall with return flanges and a perforated base. Standard catalogue product supplied in 3 meter lengths. Fittings include integral couplers. Manufactured in BS EN ISO9001:2008 and BS EN ISO14001:2004 approved facilities. Please refer to Technical section for dimensions and weights. Sheared steel (particularly stainless steel) does have relatively sharp edges and protective gloves must be worn during handling.

1.3 Alternative options

Gauges: Alternative gauges other than those indicated in the catalogue available to special order

Finishes: Pre-galvanised steel (PG), Hot dip galvanised after manufacture (HDG), Deep galvanised (high silicon steel), Stainless Steel (with pickle & passivation as special order finish), Powder coated (to customer specification)

1.4 Selecting the Size of Cable Tray Required

Before commencing the design process for a new installation it is usual to consider whether future changes in the pattern of demand for building services will impose increased loading requirements on the support system. If so, it is good design practice to allow both the physical space and


Page 5 of 38

sufficient load carrying capacity for the future addition of 25% more cables or other loading medium. Estimation of cable loads

If full details of the cabling layout are available then the likely cable load can be calculated using either manufacturer’s published information or the tables of cable weights and diameters which are given on page 6. However, it is often necessary to select a tray design in the absence of accurate information on the likely cable load. To assist this selection process a useful approach can be to choose a likely size of tray and then to estimate the maximum cable weight which is capable of being contained on it. This estimate may be arrived at using the following guide :

Note: this formula only provides an estimate of the maximum load which can be physically

contained on a tray. The ability of that tray to support such a load depends upon the spacing of its supports. Cable weights and diameters Tables 1 and 2 (next page) give typical weights and diameters (D) for PVC sheathed, steel wire armoured cables with stranded copper conductors. Tables 3 and 4 give typical weights and diameters for PVC sheathed, un-armoured stranded copper power cables. Cables with XLPE (cross linked polyethylene) insulation are usually slightly lighter so the information given may also be used for these cables too. For all other types of cable (e.g. paper insulated cable or cable with aluminium conductors) refer to the cable manufacturer’s catalogue for details and guidance. Values show approx weight and diameter of typical cables. D = Overall cable diameter.

Coupling – quick bolt fasteners (QBF)

Quick bolt couplers are a stronger, faster, easier and safer method of joining together MRF straight lengths or cut lengths of tray without the need for further drilling. Square-shafted quick bolts lock firmly into position before fixing. The nuts, which have integral washers and a serrated edge to reduce slip and improve earthing, can then be easily tightened using a power tool. Supplied in packs containing 25 pairs of couplers, 100 quick bolt fasteners (Cat. No. QBF) and a FREE power tool attachment. For tray widths 300mm and above use two additional quick bolt fixings (Cat. No. QBF) per coupler. Quick bolt couplers are not available for 50 mm wide MRF tray.

2.2 Supporting Cable Tray Systems

In practice it is often impossible to pre-determine where the couplers will be located within a straight run of cable tray. However it is well worth making some effort to roughly plan their positions during the early stages of installation. The worst position for the couplers is at mid-span. At these locations they will suffer the greatest stress. A mid-span joint should be particularly avoided on the end spans of an installation to minimise deflections. The best position for joints in a continuous installation is on quarter of the span distance on either side of each point of support.

2.3 Electromagnetic Compatibility (EMC)

In normal use cable tray is considered as passive in respect of electromagnetic influences. The installation of current carrying media may cause emissions and these media may also be influenced by electromagnetic signals from elsewhere but the degree of influence will depend on the nature of the installation and the apparatus connected to the system. A draft technical report IEC1000-S-1 provides details of the cable separation required according to the type of signal being considered and the IEE Guidance Note No.1 provides further information on the subject of EMC. However, as a basic principle, if power and signal cables can be run separately on different trays then this will significantly reduce any possibility of one electrical circuit having any undesirable influence upon another.

2.4 Earth protection

Cable tray is deemed to provide continuous support to any cables installed upon it but, because it is not completely enclosed, it does not offer mechanical protection. For this reason unsheathed, single insulated power cables should not be installed on tray, all cables should have some mechanical protection in the form of PVC sheathing, steel wire armouring or a copper covering (MICC). Where moisture may be present, copper covered cables must also be PVC sheathed to avoid electrochemical corrosion between the copper and the cable support system. Cable tray can be specifically designed to act as a circuit protective conductor (CPC), which connects exposed conductive parts of equipment to the main earth terminal and will thereby provide some protection against electric shock. For this to be acceptable the cross-sectional area of the cable support must exceed a value obtained by calculation, the formula for this calculation being given in Regulation 543-01-03 of the Wiring Regulations BS 7671. This formula takes into account the fault current of the circuit, the nature of the cables themselves and the operating time of the disconnecting device used to protect against excessive currents. Other features, such as protection of the support system against mechanical damage and corrosion (to ensure the CPC remains intact), visual identification that the support system is being used as a CPC and the impedance of the circuit must also be considered by a competent electrical engineer before tray can be used as a CPC. If armoured cables (with an integral CPC) are installed on a tray and the support system is not being used as a protective conductor, then it is generally considered as a metal part which is neither extraneous nor exposed; continuity is not an issue in this situation. Normal tray assembly methods are adequate and BS 7671 (the Wiring Regulations) impose no requirement for continuity of such metal parts unless they are being used as a protective conductor. If unarmoured cables are installed on a tray installation which is not being used as a protective conductor, consideration should be given to the possibility of damage to these cables, causing the tray to become live and hence the need to earth the support system.


Page 21 of 38

The continuity of properly fixed tray joints is such that earth continuity connectors (bonding connectors) are not necessary for any general tray application; however in special locations or hazardous areas (as described in BS 7671: Section 6) earth continuity connectors may be required, subject to consideration by a competent electrical engineer.

2.5 Thermal expansion and contraction

In locations where large variations in temperature are anticipated the design of the support system should make allowance for changes in the length of the support system due to the expansion and the contraction of the metal.

2.6 Material and Finishes

Legrand ensures that all of the materials used during the construction and finishing of their products conform to the relevant standards, a full list of which is provided on p. 142 & 143 of the Product Technical Guide. See also Section 6 of this document. In particular, the relevant standards for steel are as follows:

Finish Product Current standard/grade

G Tray less than 1.5mm thick BS EN 10130 : 2006 Grade DC01

G Tray 1.5mm and thicker BS EN 10111 : 1998 Grade 1.0332 / BS EN 10025 : 2004 Grade S275JRC

D Tray BS EN 10025-5 : 2004 Grade S355JOWP

PG Tray BS EN 10346 : 2009 Grade DX51D

S Tray BS EN 10088 : 2005 Grade 1.4404 (equivalent to S316L31)

Hot dip galvanised (G) Refer to Product Technical Guide for additional information Hot dip galvanising after manufacture is an excellent, economical protective finish used on support systems in many industrial and commercial applications. Background The galvanised coating is applied as a final manufacturing process by immersing a steel component (after various pre-treatments) in a large bath of molten zinc; the zinc forms an alloy with the steel substrate and protects the steel from corrosion in two ways. Firstly, the zinc coating surrounds the base steel with a total, tough physical barrier preventing corrosion of the steel by the surrounding atmosphere. Secondly, if steel does become exposed, e.g. at a cut edge, the zinc coating acts as a sacrificial anode and will be gradually corroded in preference to the underlying steel. Corrosion products from the zinc will also be deposited onto the steel, effectively re-sealing the surface and maintaining the integrity of the barrier.


Page 22 of 38

The life of a zinc coating is directly proportional to its thickness but in different environments this life does vary. However because hot dip galvanising has been used for many years its life in diverse environments has been well established. In the presence of certain atmospheric pollutants (such as sulphur dioxide in industrial areas) or when installed in an aggressive coastal or marine environment the rate of dissipation of the zinc will be accelerated; however in most situations hot dip galvanising remains an extremely effective and economical corrosion resistant finish. Specification

BS EN ISO 1461 provides the specification for a hot dip galvanised coating. Heavier gauges of steel will usually take up a thicker coating of zinc than lighter gauges so the standard defines the coating for different steel gauges in terms of the weight of zinc per square metre of surface area. The coating thicknesses given in the standard and their equivalent coating weights are shown below: Galvanising standard BS EN ISO 1461 : 2009

Minimum average zinc thickness

Steel thickness

Minimum average zinc thickness (microns)

Less than 1·5 mm 45

1·5 mm and thicker up to 3 mm 55

3 mm and thicker but less than 6 mm 70

6 mm and thicker

85

Note

For threaded and very small components which are spun galvanised, thinner coatings are used as recommended by BS EN ISO 1461. Deep galvanised (D)

Refer to Product Technical Guide for additional information A deep galvanised finish has all of the characteristics of hot dip galvanising but with a much thicker coating of zinc. This gives 2-3 times the life of the standard hot dip galvanised (BS EN ISO 1461) finish. Background

The life of a galvanised coating depends very much upon the degree of pollution of the surrounding atmosphere; in an industrial or marine environment corrosion of the zinc may take place at double or treble the rate which would occur in an inland environment. Thus, if heavy atmospheric pollution or aggressive conditions exist in the vicinity of an installation, it is well worth considering the benefits provided by deep galvanising. Specification

Although the appropriate British Standard for deep galvanising is BS EN ISO 1461 (the same as for hot dip galvanising after manufacture) the process requires the use of steel containing a slightly


Page 23 of 38

higher proportion of silicon; often referred to as high silicon steel. When galvanising normal mild steel the process effectively ceases after a short immersion time in the galvanising bath, giving, depending on the gauge of the steel, the coating thicknesses laid down within BS EN ISO 1461. However with silicon bearing steels the chemistry of the galvanising process changes, resulting in the zinc coating continuing to increase in thickness as long as the steel remains immersed in the zinc. Coatings up to three times as thick as the minimum requirements of BS EN ISO 1461 are both possible and practical to achieve. However the most cost effective coating thickness is usually twice the thickness required by BS EN ISO 1461. Pre-galvanised (PG)

A zinc coating can be economically applied to steel sheet immediately after its manufacture; the result, pre-galvanised steel (to BS EN 10346) can be an attractive, bright material which is suitable for non-arduous environments. Background

Pre-galvanised (or mill galvanised) steel is produced by unwinding steel coil and passing it continuously through a bath of molten zinc and then past air jets to remove excess zinc from the surface. The process is closely controlled to produce a thin, even and ripple-free zinc coating with very few imperfections. Because this pre-galvanised steel coil must then be cut to shape during subsequent manufacture of support equipment, the edges of the finished components will have no zinc coating; this aspect, together with the relatively light zinc coating provided by the process, make pre-galvanised services supports suitable for indoor, non-corrosive environments (particularly where an aesthetically attractive appearance is important) but unsuitable for humid indoor or outdoor applications. Stainless steel (S)

For most practical purposes stainless steel can be regarded as maintenance free and suffering no corrosion. Inevitably there is a relatively high price to pay for these attractive properties but, in aggressive environments or where the cost or inconvenience of gaining subsequent maintenance access is prohibitive, this initial cost premium may well be justified. Background

Stainless steel contains a high proportion of chromium (usually at least 17%) and the steel’s remarkable immunity to corrosive attack is conferred by the chromium-rich oxide film which occurs naturally on its surface. This invisible film is not only inert and tightly bonded to the surface, it also re-forms quickly if the surface is damaged in any way. The fire resistance of stainless steel is particularly noteworthy; tests have demonstrated that stainless steel cable supports can be expected to maintain their integrity for considerable periods even when exposed to direct flame temperatures exceeding 1,000°C. This may be an important consideration where the electrical circuits being supported provide for emergency power or control systems. Stainless steel is also used where hygiene is a major consideration. Its advantages in such applications are again its excellent resistance to the various chemicals and washes which are frequently used for cleaning purposes and the smoothness of surface (depending on the finish specified) which minimises the soiling or contamination that can take place.


Page 24 of 38

Specification

Many grades of stainless steel are available but the one generally used in aggressive marine environments is BS EN 10088 Grade 1-4404 (equivalent to 316L31, BS 1449: Part 2). This grade has improved corrosion resistance (particularly in the presence of chlorides) and high temperature strength. It is often used in the chloride-laden marine conditions which exist on offshore installations and in coastal regions. For less aggressive environments BS EN 10088 Grade 1-4301 (equivalent to 304, BS 1449: Part 2) is the normal grade. This grade may be used for aesthetic purposes and is commonly used in the dairy and food industries. Final finishes with mechanical brushing or polishing are often used to provide a good looking and robust surface finish. A stainless steel surface will have excellent corrosion resistance due to the chromium oxide layer on the surface of the product. With some stainless steels however, the surface areas can become subject to corrosion due to the depletion of chromium during welding. To overcome this problem welded stainless steel products are often pickled and passivated after welding. Pickling and passivation

The pickling and passivation process gives optimum corrosion resistance and is carried out under a carefully controlled operation aimed at minimising risk to both the environment and individuals carrying out the process. Pickling

The pickling process on the surface of stainless steel is carried out to remove a thin layer of metal from the surface of the component. Pickling is also used to remove weld heat tinted layers from the surface of stainless steel where the steel’s surface chromium level may have been reduced. Finally pickling can be used to remove carbon steel contamination which occurs on the component during the manufacture process and to reduce small areas around a weld which may be deprived of oxygen allowing localised forms of crevice or pitting attack to form corrosion. Passivation

A passive chromium rich oxide film naturally forms on the surface of stainless steel. Additional passivation adds a thick oxidising passive layer that is accelerated and forms a thickened protective layer. Unlike pickling no metal is removed from the surface and the passivation always occurs after the pickling has been completed. This passivation treatment reduces the corrosion risk on stainless steel and leaves a Matt grey smooth finish.

4.1 Product testing

The standard BS EN 61537 states that manufacturers must publish SWL (safe working load) details for their products, and specifies load test methods for determining the SWLs which can be supported by cable tray. There are different types of load tests, used dependant on what installation limitations the manufacturer specifies with regard to span size, possibly with reduced end span size, and positions of joints. The metal cable tray system shall follow the load test procedure in accordance with BS EN 61537:2007

4.2 Certificate of Conformity


Page 28 of 38

4.3 GOST-R certification (the Russian market)

Since 1993, the majority of imported products and equipment must be inspected to show that they comply with Russian standards. GOST R certification is one of the most common mandatory certificates. It was introduced to protect the health and safety of Russia’s population. GOST is the Russian word for "norm", and R stands for Russia. For most products, certification is needed if you wish to sell them in Russia. The main products concerned are materials in contact with food and human beings; industrial equipment for food, chemical, oil & gas, construction and other industries; mechanical and electrical goods. Also concerned are consumer products such as foodstuffs, textiles and clothes, cosmetics and perfumery, domestic goods and toys. Legrand Cable trays have achieved GOST-R certification.

5 Quality Assurance

5.1 Quality Management

BS EN ISO 9001:2008

ISO 9001:2008 is the standard that provides a set of standardized requirements for a quality management system, regardless of what the user organization does, its size, or whether it is in the private, or public sector. It is the only standard in the family against which organizations can be certified – although certification is not a compulsory requirement of the standard. Areas covered in the standard are the customer’s quality requirements, applicable regulatory requirements. The aim is to enhance customer satisfaction and achieve continual improvement of its performance in pursuit of these objectives. Legrand is proud to state that both of the manufacturing plants in the West Midlands and Yorkshire have been awarded BS EN ISO 9001:2008.


Page 31 of 38

5.2 Environmental Management

Acting on global warming, resource depletion and pollution, efforts to improve the living standards of vulnerable populations: these are all areas to which the Legrand Group can contribute through its professional expertise. The core of the Legrand Group’s mission is to offer innovative solutions that can be used to control energy consumption and improve comfort, safety and communication. The Group harnesses its teams’ skills and expertise every day in order to implement a wide range of good practices, thus ensuring the profitable, sustainable and responsible growth of its business activities. As a member of the Global Compact, the Legrand Group is committed to the concept of corporate social responsibility. 5.2.1 Control of the Group’s greenhouse gas emissions

As part of the Legrand “Climact” project, the Group is contributing to the fight against climate change by reducing its greenhouse gas emissions in a range of areas such as transportation, control of energy consumption at its units, and its product offer.

5.2.2 Ensuring the safety and well-being of its staff

The Legrand Group’s health & safety policy is continuing to make headway. Reviewed and enshrined in the Group’s Prevention Charter, and based on the ILO-OSH 2001 guideline, it deploys three key principles: compliance with nationally applicable laws and regulations; integration of safety and environmental concerns into the industrial approach; harmonisation of health & safety strategies.

5.2.3 Promoting talent and diversity

By encouraging internal mobility, training and skills development initiatives, the Group is demonstrating its commitment to promoting and respecting diversity, while at the same time regarding the diverse range of talents as an opportunity for and a key factor in the company’s growth.

5.2.4 Involvement in local community life

Group sponsorship actions, which are decided by each subsidiary, mainly focus on humanitarian actions and education, two areas which enable the Group to promote its expertise in the field of electricity. In 2007, the Group signed a partnership agreement with the French NGO “Electriciens Sans Frontières” (ESF – Electricians without borders), involving it in projects seeking to provide isolated areas with electricity supply.

Legrand mainly acts at three levels:

Eco-designed products For several years now, the Legrand Group has been committed to a continual improvement approach built around the following priorities:

Integrating the environmental management dimension into the running of its industrial units as early as possible. Currently, 84% of Legrand industrial units worldwide and 96% of those in Europe have been certified to ISO 14001.

Taking environmental concerns on board in the development process by reducing its products' environmental impact and by providing customers with all the relevant environmental information in the form of Product Environmental Profile (PEP) datasheets. Currently, 70% of Legrand's design departments worldwide implement an eco-design approach.

Controlling the substances present inside its products: Legrand is keenly aware of its obligations in the framework of the REACH regulation, and has been taking all the


Page 32 of 38

necessary steps to ensure compliance. Taking a driving role in this dynamic, Legrand indeed goes further, for example by undertaking to exclude from its future developments the use of any so-called candidate substances for authorisation under REACH whenever a technically viable alternative solution exists.

Energy efficiency

In order to meet the challenges emerging in the building sector which represent major new stakes in terms of electrical infrastructure, Legrand in 2009 set up an ambitious project named E², for Energy Efficiency, thereby clearly displaying its intention to support the various players in the electrical trade in opening up this significant new market full of opportunities for all of them. Legrand seized the opportunity of this project to set itself the goal of contributing to reliable, productive and sustainable energy consumption, especially by acting on two levers:

offering energy efficiency solutions, from system management through to efficient devices;

working in partnership with the various players in the electrical trade, particularly to enhance communication on best practices related to electrical installations.

Assisted living

To make buildings, specialist care facilities and housing accommodation safer and more accessible for all, Legrand proposes a complete range of convenient, user-friendly products designed to compensate for motor, cognitive and sensory deficiencies. Home automation solutions in particular can provide precious assistance to people in danger of losing their independence, by ensuring greater safety of movement around the house, reducing the need for repetitive everyday moves and gestures, and facilitating communication with the outside world. BS EN ISO 14001:2004

BS EN ISO 14401:2004 is the standard that addresses “Environmental Management”. This standard means that Legrand has worked to minimize harmful effects on the environment caused by it activities and work to achieve continual improvement of its environmental performance. Legrand is proud to state that its manufacturing plants in the West Midlands, Yorkshire and Durham have been awarded BS EN ISO 14001:2004.

5.3 Fire Safety of Materials

The large majority of products defined in this document are metallic. Metallic products are considered as non-flame propagating.

5.4 Safe Handling

Site deliveries should preferably only be made where suitable mechanical handling equipment is available on site. The delivered material must be treated with care. Lifting must only be carried out from the sides and the forklift truck tines must pass below a complete bundle. Tines must never be inserted into the end of the bundle unless provision is made such as special packaging and/or extended tines, otherwise the safety limits of the lifting vehicle may be exceeded and damage may be caused to the equipment being lifted. For offloading by crane suitable lifting beams should be inserted from side to side beneath a bundle and these must be sufficiently long to avoid undue pressure on the edges of the bottom components. The tensioned banding used for securing bundles of equipment during transport is not suitable for lifting purposes. When cutting this banding appropriate eye protection must be worn to avoid injury. Sheared steel (particularly pre-galvanized or stainless steel) does have relatively sharp edges and protective gloves must be worn during handling.

5.5 Storage

Most support equipment is supplied with a corrosion resistant finish which will, once the equipment is erected, have a service life of many years. However if the equipment is allowed to become wet whilst stacked awaiting installation the finish can quickly suffer from unsightly staining and powdering on the surface. This is known as Wet Storage Stain (see paragraph below). It is therefore essential that all equipment is stored in a dry, unheated environment and that the following precautions are observed to prevent deterioration on site:-

Any outer packaging should be removed from stacks immediately following delivery, before the goods are placed in store.

Store all equipment under cover, in dry, unheated premises. Do not leave any uncovered, part-used stacks lying outside for long periods.

If stacks of equipment have become wet they must be re-stacked as soon as possible with wooden battens inserted between components to allow air to circulate.

If no undercover storage is available then equipment should be re-stacked immediately following delivery and a simple shelter, using polythene or a tarpaulin, should be erected over the stored equipment to protect it from rain. This covering should not be laid directly onto the stack as air must be allowed to circulate through and around the stored goods.

Inspect stored goods regularly to ensure that moisture has not penetrated into the stacks.

Do not store the delivered material where people will walk across it.

If galvanized products are allowed to become wet whilst stacked awaiting transportation or installation the finish may quickly suffer from unsightly staining and powdering on the surface. This is commonly known as ‘wet storage stain’ and detracts from the overall appearance of the product.

Generally this condition does not however, reduce the life expectancy of the corrosion resistance of the finish. Where equipment has been affected by wet storage stain the unsightly marking will usually become much less prominent and will often disappear completely within months of installation. The stain is converted to zinc carbonate by reaction with atmospheric CO2 so providing a protective patina.

5.6 Control of hazardous substances

Legrand cable management support systems will have a surface coating of either zinc, light oil or a plastic material, depending upon the specified finish. If any welding of equipment is carried out these substances can give rise to fumes and so appropriate ventilation must be provided to ensure the exposure of the operator is kept below the statutory limits. The current occupational exposure limits for zinc oxide fumes published by the U.K. Health & Safety Executive are 10mg/m3 for short term exposure and 5mg/m3 for long term exposure.

5.7 Sustainable development

Sustainable development can be defined as development that satisfies the needs of the present without compromising the ability of future generations to satisfy theirs. Sustainable development includes, respect for the environment, and preventing the exhaustion of natural resources by the reduction of waste and the minimisation of energy consumption. REACH regulations The new European REACH regulations came into force on 1st June 2007. REACH stands for ‘Registration, Evaluation and Authorisation of Chemicals’. The main objectives of REACH are: better protection of human health and the environment against the risks that can be caused by chemicals. It also promotes better knowledge of the chemical substances used in industry. REACH regulations concern all industries and all materials that exist on the European market, whether produced in the European Union or imported, from one tonne per year. It obliges companies to register their substances with the European Chemicals Agency; otherwise, they will not be authorised for placement on the European market. Nevertheless, this registration is not applicable to substances already covered by other regulations (radioactive substances, medication, phytopharmaceutical products, biocidal products, food additives, etc.). Other categories, such as polymers, are subject to special handling. The management on WEEE and RoHS

The management of WEEE and RoHS corresponds to two European directives. D3E (2002/96/EC) deals with the framework for the management of waste electrical and electronic equipment in Europe. The RoHS recast Directive 2011/65/EU (Restriction of Hazardous Substances) concerns the composition of electrical and electronic equipment (EEE). One of the aims of these directives is to inform users of the rules to apply and the means available to manage waste electrical and electronic equipment in strict observance of sustainable development. These directives also identify the needs and problems of users and service providers, and solutions that exist or need to be created.

The aims are to handle the economic management of the WEEE sector, to organise the collection and processing of WEEE, and to implement awareness, information, and communication actions. WEEE includes a wide variety of waste, and their typical composition is too complex to be fully defined. The waste electrical and electronic equipment collection and processing system has been operational for professional WEEE since 13th August 2005. This waste essentially consists of ferrous and non-ferrous metals (10 to 85%), inert materials excluding cathode ray tubes (0 to 20%), plastics whether or not containing halogenated flame-retardant materials (1 to 70%), and specific components that are potentially hazardous to health and the environment (CFCs and other greenhouse gases). Note: cable tray systems and cable tray systems and associated supports are outside of the scope of WEEE and RoHS.

Environmental footprint Product Environmental Profiles (PEPs) specify the environmental characteristics of each product over its entire life cycle. The following points must be addressed:

Take environmental aspects into account in the design

Preservation of resources (energy, water, materials, land)

Protection of ecosystems on a global level (climate, ozone), regional level (forests, rivers, etc.), and local level (waste, air quality, etc.)

Links between environment and health
