DIN EN 14535-3:2016-04 EN 14535-3:2015 (E) 5 Introduction This Euro

    24、pean Standard gives the requirements and classification to be met for the design, dimensions, performance, and testing 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 constr

    25、uction need to ensure accordance with good engineering practice and manufacture. The classification according to this standard is the subject of a brake disc classification certificate (Annex A). DIN EN 14535-3:2016-04 EN 14535-3:2015 (E) 6 1 Scope This European Standard applies to brake discs desig

    26、ned to be fitted to railway vehicles. This European Standard comprises a type test of brake disc performance. The brake 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

    27、 defined brake pad by dynamometer tests which simulates up to one year in service when operating in the defined application 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 d

    28、iscs on railway vehicles it is not mandatory to use classified brake discs. Classified brake discs can be validated for 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

    29、 EN 14535-1 and EN 14535-2. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

    38、N 14535-3:2016-04 EN 14535-3:2015 (E) 8 5 Classification The classification of the brake disc is described by use of a performance class, which is a set of the values of brake energy, brake power and brake torque, related to the major diameter, width and type of the brake disc, at which it is type t

    39、ested to demonstrate its capability to withstand these conditions without exceeding the defined limits of structural degradation. The classification of the brake disc is summarized in as follows and recorded in the classification certificate (see Annex A): W3- C1- H3- V03/ V01 Ventilation class at s

    41、 shall be fully documented. For compliance with the standard both the common requirements specified throughout the standard and the following documented items shall be satisfied: definition and identification of the brake pads (7.2); drawing of the wheel (In case of wheel mounted brake disc); wheel

    42、class (8.2) and wheel diameter if the wheel class is W0; method for preliminary and final verifications (8.3); performance and endurance target class (9.2); heat dissipation target class (10.2); ventilation target class (12.2); method for the verification of pass and fail criteria (9.4, 10.4, 11.4,

    43、12.4); imbalance class according to EN 14535-1 and EN 14535-2 and value of imbalance if it isnt defined; maximum values for corrugation, swashing and buckling (9.4, 10.4).

    44、properties for brake disc classification 7.1 General requirements Brake disc and pad materials used for the performance tests shall be in accordance with the specifications of this standard. The brake disc and pad interaction couple, which is used as a reference, shall be defined. Should the classif

    45、ication be required with more than one reference pad, then only the performance, endurance and heat dissipation tests, are required to be repeated with the further pad type. If brake disc dimensions are changed by no more than 1 % from existing models, this brake disc shall be included in the same p

    46、erformance class of the existing brake disc without re-testing. In case of wheel mounted brake discs, all the tests shall be performed with the brake disc assembled on a wheel. Details for the execution of the tests are described in the following clauses. The operators shall monitor the product inst

    47、alled during the trial test according to their specific evaluation criteria. 7.2 Test specimens Three specimens shall be provided for a classification. The specimens shall be produced under serial conditions and the raw materials shall come from the same casting or forging batch. The production data

    48、 shall be confirmed by certificates. Dimensional and material controls: Specimen 1. The classification tests shall be carried out in the following order using the reference specimens: performance and endurance test: Specimen 2; centrifugal test: Specimen 2; ventilation test: Specimen 3; heat dissipa

    49、tion test: Specimen 3. The pad type shall be defined and used for all the classification test. The pads used for each test shall be identified. 7.3 Preliminary and final verification sequences Before starting the tests and after any test that may influence or change the physical integrity of the tested brake disc the verifications that are listed in Table 3 shall be executed. 7.4 Pass and fail criteria The pass and fail criteria for every test are
