Electronics Equipment reliability test stard
1, ISO
In the International Organization for Stardization, ISO/TC22/SC3 is responsible for stardization in the field of automotive electrical electronic technology. The application environment of automotive electronic products includes electromagnetic environment, electrical environment, climate environment, mechanical environment, chemical environment, etc. The current ISO stard environmental conditions test stards for automotive electronics mainly include the following aspects:
ISO16750-1: Road vehicles-Environmental conditions tests of electrical electronic products: General rules
ISO16750-2: Road vehicles-Environmental conditions tests for electrical electronic products: Power supply environment
ISO16750-3: Road vehicles-Environmental conditions tests for electrical electronic products: Mechanical environment
ISO16750-4: Road vehicles-Environmental conditions tests of electrical electronic products: Climatic environment
ISO16750-5: Road vehicles-Environmental conditions tests for electrical electronic products: Chemical environment
ISO20653 The level of protection of automotive electronic equipment against foreign objects, water contact
ISO21848 Road vehicles-Power supply environment for electrical electronic equipment with a supply voltage of 42V
At present, the environmental test stards for domestic automotive electronic products are mainly stipulated in accordance with the technical conditions of the products. The National Automotive Stardization Technical Committee (SAC/TC114) is ulating corresponding national industry stards with reference to ISO stards.
The ISO stard has been wiy adopted by European American car manufacturers, while the requirements of Japanese car manufacturers deviate greatly from the ISO stard. In order to ensure that the stard limit is reached, the environmental condition stards of the internal control of the automobile manufacturers are generally more stringent than the requirements of ISO .
2 , AEC series of stards
In the 1990s, Chrysler, Ford General Motors established the Automotive Electronics Committee (AEC) to establish a set of common parts qualification quality system stards, AEC established quality control stards. AEC-Q-100 The certification specification for chip stress testing is the first stard of AEC . AEC-Q-100 was published in 1994 , because parts that meet the AEC specification can be used by the above three automakers at the same time, it promotes the willingness of component manufacturers to exchange their product characteristic data, promotes the versatility of auto parts The implementation of the AEC stard has gradually become a general test specification for automotive electronic components.
After 10 years of development, AEC-Q-100 has become a general stard for automotive electronic systems. After AEC-Q-100 , AEC-Q-101 for discrete components AEC-Q-200 for passive components were successively ulated, as well as guiines such as AEC-Q001/Q002/Q003/Q004 Principle.

Part Summary of common test conditions for automotive electronics
Different test environment conditions will have different impacts on the product. The environmental reliability requirements of different parts of the car are different. For example, for the temperature environment conditions, the upper part of the front dashboard of the car requires a maximum of 120°C, the lower part of 71°C, the cabin floor. 105°C so on. Therefore, the environmental reliability test conditions of automotive electronic products with different uses different installation positions are not the same. The following table lists the main environmental test items test conditions for some common automotive electronic products.
