Foreword
This Standard was drafted in accordance with the rules given in GB/T 1.1-2009
“Directives for standardization - Part 1. 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
- 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
- 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
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.
Main drafters of this Standard. Lin Dahai, Hu Shuibing, Xiao Shuibo, Shi
Ruikang, Wang Shanghua.
