Foreword
This Standard was drafted as per the rules specified in GB/T 1.1-2009 Directives for
Standardization – Part 1. Structure and Drafting of Standards.
This Standard is the modification against QC/T 501-1999.
Compared with QC/T 501-1999, this Standard has the major changes as follows.
--- Delete the starting time and impact requirements;
--- Add the quiescent current, over-voltage, salt spray, reverse voltage,
electromagnetic compatibility, protection test and requirements;
--- Reduce the voltage drop of the flasher correspondingly;
--- Adjust the electrified rate parameter of the flasher;
--- Adjust the durability test time slightly according to several enterprises’ standards;
appropriately reduction of time can meet the actual working conditions;
--- In the aspect of test circuit diagram, considering the current state of existing
products, give Line-3 and Line-5 product lines diagrams.
This Standard was proposed by and under the jurisdiction of National Technical
Committee of Auto Standardization (SAC/TC 114).
Drafting organizations of this Standard. Anhui Jianghuai Automobile Co., Ltd., China
Automotive Technology & Research Center, Beijing Eight Sites Park Aobo Sci-Tech
Development Co., Ltd., BAIC Motor Corporation Limited, Faw Haima Automobile Co.,
Ltd., Zhengzhou Yuebo Automotive Electronics Co., Ltd., and Sichuan Fanhua
Enterprise Co., Ltd.
