BS EN 15329:2015EN 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

21、take all requisite steps to ensure on his part that the quality of design and production are state of the art. BS EN 15329:2015EN 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

22、made of non-ferrous materials are not subject to this European Standard. This European Standard contains requirements for design, evaluation testing of conformity and serial production monitoring.

31、tandards. 5.2 Material for brake block holder The brake block holders shall be produced from one of the following: steel (cast, forged or rolled), grey cast iron. Welded designs are permitted subject to agreement between manufacturer and customer. Welding shall only be used for rectification of manu

32、facturing 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 b

33、y the operator. BS EN 15329:2015EN 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 app

34、lied, 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 mate

35、rial 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 separa

36、tely 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

37、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 accommodati

38、ng 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

39、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

40、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

41、 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 du

42、e to manufacture shall not exceed 2 mm. BS EN 15329:2015EN 15329:2015 (E) 9 7 Markings 7.1 General Brake block holders, brake shoe keys/insert springs covered by this document shall be provided with permanent markings, as described in 7.2 and 7.3. The marking on the brake block holder shall also be

43、legible when the brake block is fitted. 7.2 Brake block holder The brake block holders shall be marked permanently. The markings shall be applied raised or recessed. The area in which the markings are to be applied shall be shown in the drawing. The following details are to be provided: size of the

44、brake blocks employed, e.g. (2 250 mm); outside radius of the brake block, e.g. (560 mm); ownership sign of the railway and year of manufacturing; dimension of the bore-hole for the bushing of the bearing pin, e.g. 60 mm; interchangeability sign and dimensions of the markings according to Annex G. 7

45、.3 Brake shoe key and brake block key The brake shoe key shall be marked in raised letters in a recessed panel with the markings of the manufacturer and the year of manufacturing. The markings shall not protrude above the surface of the key. For keys manufactured by rolling, the markings may also be

46、 recessed, but care shall be taken to ensure that the tool used for this purpose does not have any sharp edges which might lead to the creation of fatigue fractures. 8 Type testing 8.1 General 8.1.1 Elements of type testing Type testing consists of material and component testing. The components pres

47、ented for acceptance shall comply with the technical documentation for series production (dimensional accuracy, surface conditions but without painting treatment of the surface, material). 8.1.2 Material testing Within the framework of material testing, the manufacturer shall submit all test certifi

48、cates concerning structural composition and physical/mechanical properties to the customer/user for inspection and approval. The materials used shall exhibit toughness, stipulated by a material standard, down to 30 C. The manufacturer shall also ensure that the material used exhibits sufficient toug

49、hness down to 50 C to exclude any brittle fracture behaviour. BS EN 15329:2015EN 15329:2015 (E) 10 8.1.3 Component testing The test shall be performed on the complete component at (+20 5) C and under laboratory conditions according to 8.2. If required by the user/customer, component testing may also be performed at sub-zero temperatures or under other operating conditions which shall be agreed upon between the manufacturer and the customer. 8.2 Type testing for brake block holders 8.2.1 Static loading 8.2.1.1 Static loading with the spec
