EN 15329:2015 (E) 5 Introduction The requirements of this European Standard cannot be laid down in such detail as to ensure defect-free design and production without obstructing further development. It is therefore essential for each manufacturer himself to take all requisite steps to ensure on his part that the quality of design and production are state of the art. SIST EN 15329:2015
EN 15329:2015 (E) 6 1 Scope This European Standard applies to brake block holders and brake shoe keys installed on railway vehicles. Brake block holders and brake shoe keys made of non-ferrous materials are not subject to this European Standard.

Welded designs are permitted subject to agreement between manufacturer and customer. Welding shall only be used for rectification of manufacturing defects, when subject to a formal procedure. 5.3 Material for brake shoe key and brake block key The selection of the material and the manufacturing process are left to the discretion of the manufacturer but they shall comply with the technical specifications and/or the drawings approved by the operator.

EN 15329:2015 (E) 8 5.4 Corrosion protection If corrosion protection is required, it shall be agreed between manufacturer and customer. 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 Brake block holders 6.1.1 General The purpose of the brake block holders shall provide secure mounting and positioning of the brake block made of grey cast iron, sintered material or composite material. Sprues, suction heads and sharp edges caused by manufacturing shall be removed. Cast brake block holders shall be normalized. Brake block holders should be designed to accommodate: — one brake block (see Figure A.10 and Figure B.11); — two brake blocks securely mounted separately in the brake block holder (see Figure A.9 and Figure B.10); — two brake blocks mounted separately but with movable supports (see Figure C.1). The curvature of the contact surface of the brake block holder with the brake blocks shall be smooth and have the same radius as shown on the figures. The entire length of the contact surface shall be perpendicular to the longitudinal centre plane of the brake block holder so as to ensure large surface contact with the brake block. The same applies to the clearance of the key-hole eyes for guiding the brake shoe key and to the recesses for accommodating the brake block mounting cams. The brake block holder shall not become permanently deformed at the maximum brake force. The suitability of the brake block holder shall be demonstrated by determining its fatigue limit by means of the test forces and number of cycles stipulated in Clause 8. Repair welding is not permitted. 6.1.2 Dimensional accuracy In order to ensure the interchangeability of the brake block holders and the brake blocks – nationally and internationally – the main dimensions of the brake block holders shall be as per the circled areas in the figures given in Annexes A and B. 6.2 Brake shoe key/Brake block key 6.2.1 General Some examples of brake shoe keys and brake block keys are given in the figures in Annex C and Annex D. The customer approves the types used. The surfaces shall be smooth and free from corrosion. Burrs and sharp edges shall be removed before treatment, the required hardness shall be indicated in the technical documentation. 6.2.2 Dimensional requirements The dimensional characteristics shall ensure the interchangeability and shall be agreed between the manufacturer and the customer, and indicated in the drawings. Distortions of the brake block key due to manufacture shall not exceed 2 mm. SIST EN 15329:2015
