2. FIRE AND SMOKE FILE

12

• List of materials and components

• Fire and smoke certificates

• Requirements according to STM S 001


LIST OF MATERIALS AND COMPONENTS

In order to justify the conformity of a rolling stock concerning fire safety, a list of materials and components has to be established according to EN 45545-2.Below, the table used by SNCF:


FIRE AND SMOKE CERTIFICATES

14

• All tests required by EN 45545 shall be carried out by laboratories accredited for these tests according to EN ISO/IEC 17025.

• Laboratories should not write validity date on certificates.

• There is no validity date in the EN 45545-2.

Example of report :


REQUIREMENTS ACCORDING TO STM S 001

15

• This document describes the application of EN 45545 by SNCF and RATP companies.

• It gives more precisions in the description of materials and components.

• It deals with essential objectives of fire safety :Minimize the effect of fire in terms of heat, smoke and toxic gases.

• It specifies the validity of certificates : 5 years



16

IN Interiors Details Requirement

IN9A

Tables, folding table tops, and

toilet wash basins.

Type A – Upper surfaces

All tables and toilet wash basins (including surrounds).

Seats tables

(tables on the back of seats or housed in the armrest for example, are covered by products IN 9A and IN 9B)

R2

IN 16 Interior seals

Longitudinal seals such as window seals, door joints, panel connections, joints of chests or cabinets of equipment

R22







19

F Furniture Details Requirement

F Seats accessoriesFoot of the seat, footrests, magazine rack, cup holders.

According table 3 of EN 45545-2 :

R1 or R22 in function of the exposed area



20

E Electrotechnical equipment Details Requirement

EL2 Cable containment

(linear product)

Cable containment surface related (cable duct, cable conduit).

See 5.3.5

Braided sleeving, corrugated pipes, fixing and connecting fittings

See Table

8 and

Table 9 of EN 45545-2

EL7A Choke and coils (1)– Interior

Chokes for supply line filtering, coils for air cooled transformers, including spacers and air guiding plates (rated voltage ≤ 3000V)

R22

EL7B Choke and coils (1)– Exterior

Chokes for supply line filtering, coils for air cooled transformers, including spacers and air guiding plates and traction motor winding insulation (rated voltage ≤ 3000V)

R23



21

R 26

See text on EL10 products.

Small electrotechnical products : EL10

•EN 45545-1 in the scope precises that «The protection of passengers and staff is essentially based on measures to […] minimise the effects of fire in terms of heat, smoke and toxic gases on passengers or staff through the specification of materials installed on railway vehicles (Part 2)”

•Requirement R26 does not allow to respect this sentence due to the lack of smoke testing

•Grouping rules because non-listed products

•R26 + R22 for interior products

•R26 + R23 for exterior products



23

• Casing : external surface of small electrical component (see IEC 60529 (or EN60529) §3.1 or IEV 826-03-12) against direct contact. This external surface reduce risk of fire to propagate from inside toward outside the electrical equipment and so to ignite other component located in it vicinity.

• Casing has to fulfil the NLI rules (Chap 4.3) in term of fire ands smoke qualification level.

• No requirement apply to parts located inside this casing .

• This proposal is due to : • very small quantity of O2 , • fire &smoke qualification of casing, • very low weight/volume of combustible

material in each casing



24

§ 4.7 Products to be approved on functional necessity

•Respect of essential safety requirements defined in EN 45545-1

•Evaluation file to justify the application :

• Valid NF F 16-101, NF F 16-102 certificates

• Demonstration of the nonexistence of a product in accordance with EN 45545-2 and other performance needed by the required functions of the product

• Inclusion of the return of experience or data from full-scale test on rolling stock

• The absence of possible use of a satisfactory alternative product


3. HIGHLIGHTING DEVIATION MANAGEMENT AT SNCF

25

• Non-compliance NF F but compliance EN

• Non-compliance EN but compliance NF F

• Non-compliance NF F and non-compliance EN


NON-COMPLIANCE NF F BUT COMPLIANCE EN

26

• If the contract for a rolling stock is according to NF F :

• Contractual deviation request

• The fire risk is mastered by a product compliant with EN 45545

• If the contract for a rolling stock is according to EN 45545 :

• Contractual deviation request

• The fire risk is mastered by a product compliant with NF F 16-101, NF F 16-102

NON-COMPLIANCE EN BUT COMPLIANCE NF F


NON-COMPLIANCE NF F AND NON-COMPLIANCE EN

27

• Standard deviation request

• Demonstration of fire risk assessment

• Use of § 4.7 according to STM S 001


CONCLUSION

28

• STM S 001 is a document written to help users of EN 45545-2:

• To have more examples of listed products

• To have complementary requirements in accordance to EN 45545-1

• This document could help during the revision of EN 45545-2
