identical text or by endorsement, at the latest by February 2021, and conflicting national standards shall
be withdrawn at the latest by February 2021.
Attention is drawn to the possibility that some of the elements of this document may be the subject of

This document supersedes EN 45545-2:2013+A1:2015.
This series of European Standards Railway applications — Fire protection on railway vehicles consists of:
— Part 1: General;
— Part 2: Requirements for fire behaviour of materials and components;
— Part 3: Fire resistance requirements for fire barriers;
— Part 4: Fire safety requirements for railway rolling stock design;

The main changes from EN 45545-2:2013+A1:2015 are:
— integration of the new test standards:
— deletion of Annexes A and B and reference to EN 16989;
— now, EN 16989 is given in Clause 2, Normative references;
— in Table 2, EN 16989 appears for F1 product;
— in Table 5, modification of R18 requirement to be in accordance with EN 16989;
— in Table 5, adding of footnote d to be in accordance with EN 16989;
— deletion of Annex C and reference to EN 17084;
— now, EN 17084 is given in Clause 2, Normative references;
— in Table 5, EN 17084 is now the reference instead of EN ISO 5659-2 : 50 kWm- for the
parameter CIT ;
G
— in Clause 2, Normative references, new standards appear:
— EN 16989, Railway applications — Fire protection on railway vehicles — Fire behaviour test
for a complete seat;
— EN 17084, Railway applications — Fire protection on railway vehicles — Toxicity test of
materials and components;
— EN 60695-1-40, Fire hazard testing — Part 1-40: Guidance for assessing the fire hazard of

percentage mass of organic material is less than or equal to 6 %. »;
— 4.2.e, modification « a product, other than an electric cable:
— meeting a requirement at two different thicknesses with identical formulation and density
(of each layer), shall be considered to comply with the requirement at all intermediate
thicknesses. A product meeting a requirement at the maximum testable thickness shall be
considered to comply with the requirement at greater thicknesses;
— meeting a requirement at two different densities, shall be considered to comply with the
requirement at all intermediate densities. The material with a differing density shall have
identical formulation and thickness. »;
— 4.2.g, adding of « or with substrates representative of the end use condition in accordance with
5.3 »;
— 4.2.h, adding of two new bullet points:
— the technical cabinet contains only mechanical or low power electrical equipment. The
cabinet sheets are closed and made of aluminium, steel or glass. The enclosed volume
is ≤ 0,1 m . Covered openings (e.g. by connectors or switches) are acceptable;
— the technical cabinet sheet material is made of aluminium or steel and the enclosed volume
is ≤ 0,5 m . For any individual surface of the cabinet, the total area of all openings in that
surface shall be less than 1/1000 of the nominal surface area;
— 4.2.j, modification « for organic coatings applied to non-metallic surfaces, the full specified test
requirements of chapters 4.3 till 4.5 are mandatory; »
— 4.2.k, modification « for organic coatings applied to products conforming to 4.2 a), ISO 5658-2 or
EN ISO 9239-1 flame spread tests shall be carried out, but other test requirements such as heat
release, smoke emission and toxic gas emission tests are not required if the nominal coating
thickness, including any surfacing filler for exterior products is < 0,3 mm, or for interior products
the nominal thickness of organic coating is < 0,15 mm; »
— 4.3 : modifications:
4.3.1 General
Products compliant to Table 2 or Table 3 are excluded from the grouping assessment.
No requirements apply to products with a combustible mass of ≤ 10g in touching contact only
with a product compliant to Table 2 and Table 3.
To assess products within the grouping rules the following parameters have to be considered.
Products shall be assessed within the grouping rules if:
— the exposed area of each product is ≤ 0,2 m ; and
— the combustible mass of each product is > 10 g or they are in touching contact with another
unclassified combustible product; and
— the horizontal distance is ≤ 20 mm and the vertical distance is ≤ 200 mm to a combustible
product not assessed to Table 2, Table 3 or R24 according to rule 2; and
— they are not fully separated by a product compliant with the fire integrity requirement of
5.3.7.
The combustible masses of the products in this group shall be summed. The assessment process
described in 4.3.2 to 4.3.4 is visualized in the flow chart in Figure 1.
