5 Materials
5.1 General

The ferrous materials used for the manufacturing of brake block holders and their components shall comply with

relevant standards of material (as for instance welded design shall be in accordance with EN 15085).

Declaration of conformity with standards (e.g. with EN 10204 or internal specification) shall be provided.

5.2 Material for brake block holder
The brake block holders shall be produced from one of the following:
— steel (cast, forged, rolled or welded);
— grey or nodular cast iron.
5.3 Material for brake block key

The selection of the material and the manufacturing process are free and shall comply with the technical

specifications and/or the drawings.
5.4 Corrosion protection

If corrosion protection is applied, it shall not contain any components constituting a hazard for the staff coming

into contact with them. Should paint colouring be applied, care shall be taken to ensure that bearing points for

bolts, bushes and moving parts are free from paint.
6 Design
6.1 Environmental conditions
6.1.1 General

For vehicles used in “general operation” or “GE” (various formations of vehicles from different origins; train

formation not declared at design stage) and using non-integrated brake rigging, all the environmental

requirements listed shall be taken into account within the design concept of the components. However only the

assessment tests listed in Clause 8 shall be performed. The remaining proofs are to be presented in the

declarations of conformity.

For other vehicles any deviation on below environmental conditions is allowed. Any special requirement shall

be declared in a specification.
6.1.2 Ambient temperature

The brake component shall be able to operate within the temperature class TX in accordance with EN 50125-1,

where the upper limit for TX shall be raised up to +70 °C for the external air temperature.

6.1.3 External air humidity

The following humidity levels shall be considered for the external environment (EN 50125-1:2014, 4.4):

— yearly average: 75 % relative humidity;
— on 30 days in the year continuously: between 75 % and 95 % relative humidity;
— on the other days occasionally: between 95 % and 100 % relative humidity;
— maximum absolute humidity: 30 g/m occurring in tunnels.
