Structure and drafting of standards”. This Standard replaces QC/T 316-1999 “Bench Test Methods of Fatigue Strength for Automobile Service Brake”. Compared with QC/T 316-1999, the main changes in this Standard are as follows. - modified the standard layout format so as to comply with GB/T 1.1 layout requirements; - listed the symbols involved in the standard separately (see Clause 2 of this Edition); - combined test equipment and test conditions into test related requirements (see Clause 3 of this Edition, Clause 2 and Clause 3 of Edition 1999); - added requirements for brake pressure increase and decrease rates (see 3.1.2 of this Edition); - added brake torque calculation method for blue-axis plated passenger car (see 3.2.2 of this Edition); - added brake duration (see Figure 1 of this Edition, 3.5 of Edition 1999); - added test cycle (see 4.2 of this Edition); - added brake torque stabilization time (see Figure 1 of this Edition); - deleted the chapter on test equipment and operation methods, and combined related content into the test methods (see Clause 4 of this Edition); - deleted Annex A and Annex B. This Standard was proposed by and shall be under the jurisdiction of National Technical Committee on Automobile of Standardization Administration of China (SAC/TC 114). Main drafting organizations of this Standard. China First Automobile Co., Ltd. Technology Center, Asia Pacific Mechanical and Electrical Group Co., Ltd., Longzhong Holding Group Co., Ltd.
