BS EN 14535-3:2015EN 14535-3:2015 (E) 5 Introduction This European Standard gives the requirements and classification to be met for the design, dimensions, performance, and tes
37、ting of the brake disc and “pad and brake disc friction couple“. These requirements need to be proven in sufficient detail by dynamometer tests. Quality of design, workmanship and construction need to ensure accordance with good engineering practice and manufacture. The classification according to t
38、his standard is the subject of a brake disc classification certificate (Annex A). BS EN 14535-3:2015EN 14535-3:2015 (E) 6 1 Scope This European Standard applies to brake discs designed to be fitted to railway vehicles. This European Standard comprises a type test of brake disc performance. The brake
39、 disc is tested for energy conversion and dissipation, ventilation characteristics as well as mechanical integrity. The classification qualifies a brake disc in conjunction with the defined brake pad by dynamometer tests which simulates up to one year in service when operating in the defined applica
40、tion class. It does not define the application and the brake performance in specific trains. NOTE For this purpose, additional tests may be necessary. For the application of brake discs on railway vehicles it is not mandatory to use classified brake discs. Classified brake discs can be validated for
41、 the use on railway vehicles for higher performance applications with additional tests. This standard describes the type test procedure for brake disc classification as specified in EN 14535-1 and EN 14535-2. 2 Normative references The following documents, in whole or in part, are normatively refere
42、nced in this document and are indispensable for its application. For dated references, only the edition cited applies.
