European Certification Board For Mineral Wool Products (EUCEB)

1. Purpose

In accordance with the Constitution of the European Certification Board for Mineral

Wool Products (EUCEB), the present rules set out (i) the principles for obtaining the

right to use the EUCEB’s registered Trademark (“the Trademark”), which certifies that manufactured fibres have a chemical composition within the ranges of non-classified reference fibres that have been tested in accordance to the European protocols to be in conformity with Note Q of the Regulation on the Classification, the Labelling and the Packaging of substances and mixtures (CLP Regulation,

Regulation (EC) n° 1272/2008) (“the Regulation”) as currently in force and any similar successive legislation, (ii) the principles under which the use of the EUCEB Trademark is authorized and (iii) rules for the process of verification in order to ensure continued compliance with said ranges of non-classified reference fibres and with the EUCEB rules for verification and resulting certification.

2. Original Application for the use of the Trademark

2.1 On request, the EUCEB Board may grant (or may grant conditionally) manufacturers of mineral wool products, as specified in the certificate supplied by the external independent certification body, the right to use the registered Trademark. Such a right is non-exclusive and non-assignable and does not entail any right to grant sublicenses. It can moreover be revoked at any time by the EUCEB Board in case of non-compliance with the present rules, as well as the EUCEB’s Constitution and the Regulation.

2.2 Application shall be made in writing to the permanent office of EUCEB, Avenue Louise 375/4, 1050 Brussels, Belgium. The application should be accompanied (i) by a legally binding undertaking (Appendix 1), (ii) by the results of the certification carried out by an independent certification body or equivalent certification, as further defined by the EUCEB Board and (iii) any other test results, proof of ownership of such results or of the legitimate use thereof, as may be required by the external independent certification body or by the EUCEB Board. The adequacy of the application shall be determined by the Board in its own discretion, such discretion not to be abused.

2.3 The Board will examine the application. Decisions of the Board shall be made in accordance with the Constitution.

2.4 Upon approval of the application by the EUCEB Board, EUCEB shall grant the applicant the right to use the Trademark as per Article 5 of the Constitution and the present rules and fix the fees to be paid on a yearly basis for EUCEB membership and continued used of the Trademark.

04 The executive rules for the use of the trademark V05

3. Supervision

3.1 The Board is entitled and required to supervise (or to have supervised) that the product fibres placed on the market by the Members of the Association under the EUCEB Trademark correspond in their chemical analysis to those that have been tested and which are in compliance with the non-classification criteria of Note Q of the Regulation. The supervision must be documented to the Board by a supervision contract with an independent inspection office or inspection agents.

3.2 All users of the Trademark must ensure themselves that they are in compliance with the conditions and criteria as defined by the EUCEB Board, in particular Appendix 2. They have a duty to ensure quality control and maintain careful records of all tests, which they themselves have undertaken. Independent third party scientists will have the right to see these records on confidential basis at any time, to request and receive further samples, or to use samples commercially available in order to ensure that compliance is reached.

3.3 If inspection results or samples show that compliance with Appendix 2 is not reached, or if there is a complaint about the product, the external independent certification body and/or the Board may decide that a further inspection has to be carried out by an independent inspection office or inspecting agents. In the event that the second inspection reveals non-conformity with the present Rules, the infringement procedure will be started.

3.4 If a complaint about a product is unjustified, cf. Article 3.3, the complainant must pay any and all costs connected to the inspections.

4. Infringements

4.1 If it is established by the Board that there has been infringement by a Trademark user of the conditions set out in Sections 2 and/or 3 above, the Board may decide the following, depending on the severity of the infringements:

Increase frequency of internal inspections.

Inspections of the results of the internal quality control system of the applicant by an external scientific expert and/or chemical analysis.

Increased external inspection up to 4 inspections per year and this for a period of 1 year. In the event that one new inspection reveals non-conformity with the EUCEB Rules, the right to use the Trademark shall immediately be revoked without further notice.

Page 3 of 3

04 The executive rules for the use of the trademark V05

A short or long-term removal of the right to use the Trademark. In such a case, the licensee shall immediately cease to use the Trademark and shall delete or remove the Trademark from, or, where such deletion or removal is not reasonably practicable, destroy all goods, stationary, advertising material and all other materials and documents in its possession or under its control.

Or any other decision.

4.2 If the Board decides to revoke the right to use the Trademark, cf. Article 4, or annual fees are not paid in accordance with Article 2.4, all certifications have to be returned, and the use of the Trademark stopped immediately.

4.3 If possible, the Trademark user has the right to be heard before any of the measures mentioned above are taken. Decisions of the Board under this Section 4 shall be made by simple majority of the members of the Board.

5. Re-establishment of the right to use the Trademark

The procedure for applying for the registered Trademark is set out in Article 2. The Board may, however, insist on additional conditions being met.

6. Belgian law and courts

The present rules shall be exclusively governed by and construed in accordance with the law of Belgium, without regard to any conflict of law provisions. Any dispute arising in connection with the present rules shall be submitted to the competent court in Brussels.

05 Exhibit 3 - The chemical range V05.doc V05

EXHIBIT 3 – The Chemical Range

A manufactured fibre should be regarded as being equivalent to an in-vivo tested fibre, if the

chemical composition falls within the following limit rules:

The maximum variation in the measured oxide compared to the tested fibre shall be:

- For a concentration above 15%: the maximum permitted variation is +/- 10% with a

maximum of 2.5% points

E.g.: For a concentration of 20% = Variation is between 18 and 22%

E.g.: For a concentration of 40% = Variation is between 37.5 - 42.5%

- For a concentration below or equal 15% and higher than 2%: the maximum permitted

variation is +/- 1.5% points

E.g. Concentration of 10% => Variation is between 8.5 and 11.5%

- For a concentration below or equal 2%: the maximum permitted variation is +/- 1%

points.

E.g. Concentration of 1.5%:= Variation is between 0.5-2.5%

The rules apply to components or sum of components, i.e. CaO + MgO and Na2O + K2O

are each treated as one component

The chemical composition should account for at least 98% of the components.

For the following component or sum of components only the minimum-limit is relevant:

CaO + MgO

Na2O + K2O

B2O3

P2O5

Al2O3 (if Al2O3 19%)

For the following component only the maximum-limit is relevant:

5. Proof of Conformity

Every manufacturer obtaining certificate to use the Trademark undertakes to comply with conformity between the tested fibres and those, which are offered for sale.

In order to ensure conformity that the chemical compositions of the fibres are within the acceptable range, cf. enclosure from the fibres tested in the report submitted to EUCEB and/or to the independent certification body, an external repetitive conformity inspection shall take place at least twice per calendar year (the first repetitive external conformity inspection should take place between January 1st and June 30th whereas the second repetitive external conformity inspection should take place between July 1st and December 31st). The time between two repetitive conformity inspections should be at least 4 months. The inspection splits up into sampling and determination of the chemical composition of the sample.

The sampling date is the date, which defines the period of the year the sampling has been done (first half or second half).

The samples to be tested shall be obtained from a production line or commercially available products. Collection shall be made by an accredited sampling institute duly qualified by the Board or by the independent certification body as competent to act in this domain.

The external inspection report, which should be submitted to the Board or to the independent certification body, must include:

- Details of manufacturer

- Designation of the fibres tested (e.g. trade name or other identification).

- Inspection office

- Time or period of the inspection

- Details of the inspection procedure

- Chemical composition of the material examined.

- Additionally the Sampling Institute shall monitor the self-control system by checking that the chemical composition is measured and recorded at least once per week.

09 Regulations for the use of the Trademark V03.doc

Special regulations for the use of the EUCEB-Trademark on packaging

films and for further use in printing

The value of a Trademark on the market depends largely on its recognition by third parties.

This requires the utmost possible use of the Trademark in a uniform way. Therefore, in

addition to the regulations set out in Exhibit 2 of the EUCEB-constitution, the Management

Board has established the following regulations for a uniform use of the Trademark.

Any further use of the Trademark not mentioned hereunder is subject to request to and

approval by the Management Board.

1) Use of the EUCEB-Trademark on packaging films

Packaging films with the Trademark printed on must meet the following requirements:

The Trademark must be printed in a size between 5 and 25 cm, the Trademark must be

free from distortion.

Exactly one Trademark in each rapport (repetitive printing format) may be placed.

The Trademark must be printed uniform black with the following exception:

Producers, which do not use black colour for any further information on the packaging

films may as an alternative uniformly use upon request to and approval by the EUCEB

Management Board for the Trademark the darkest colour, which is used for any further

information. The request must be accompanied by an illustration of the printing

format. Other colours than those in use on the packaging films except black must not

be used for the Trademark.

A reference pattern of packaging films and printing formats must be deposited at the

EUCEB-secretariat.

2) Further use of the Trademark

In any other case of use in printing (e.g. use in brochures, pamphlets, leaflets, letters, etc.)

the Trademark must be used exclusively in black.

The Management Board points the EUCEB-members to the provisions of the Legal

Undertaking. Any non-obedience to the EUCEB-constitution and subordinate regulation

or guidance without written approval by the Management Board may be considered as an

infringement and dealt with accordingly.
