Foreword
This standard was formulated with reference to ISO 8092.1 ~ .4 series standards. This standard is divided into five parts, under the general title of the connectors for on-board electrical wiring harnesses:
- Part 1: Definitions, test methods and general performance requirements (the automobile part)
- Part 2: Test methods and general performance requirements (motorcycle part) - Part 3: Tabs for single-pole connections - Dimensions and specific requirements - Part 4: Tabs for multi-pole connections - Dimensions and specific requirements - Part 5: Tabs for single- and multi-pole connections - Dimensions and specific requirements
With the continuous improvement of China's automotive product technology, the requirements for electrical plug-in device are getting higher and higher. Therefore, in the process of formulating the test method and performance requirement standards of the connectors for electrical wiring harnesses, with reference to ISO 8092.2:1996, the vehicle manufacturers generally think that the requirements of ISO 8092 for the performance requirements of connector are relatively low; they hope to improve performance requirements. However, these improved performance requirements are too high for motorcycles. Therefore, through negotiation, the test methods and general performance requirements for connectors are formulated in two parts: automobile and motorcycle. In the Part 1: Definitions, test methods and general performance requirements (the automobile part), on the basis of using ISO 8092.2:1996, improve some performance requirements and add some performance requirements and corresponding test methods; in addition to the adoption of some contents of international standards, the remaining test methods use national standards and related industry standards. In Part 2: Test methods and general performance requirements (motorcycle part), technical content identically adopts ISO 8092.2:1996. QC/T 417.3 ~ QC/T 417.5 identically adopts the contents of ISO 8092.1, 3, 4:1996, respectively. This series of standards replace QC/T 417-1999, QC/T 418-1999, QCn 29012-1991, from the date of implementation.
This series of standards are proposed by the State Machinery Industry Bureau. This series of standards shall be under the jurisdiction of the National Automobile Standardization Technology Commission.
Drafting organization of Part 1 of this series of standards: Hebi Tianhai Automobile Electric Co., Ltd. The main drafters: Wang Laisheng, Wang Rongxi.
