General rules of environmental testing methods for automotive electronic equipment 1. Scope This standard specifies a uniform test method in order to evaluate the performance of automotive electronic equipment (hereinafter referred to as “equipment”) under various environmental conditions, which use a power supply of nominal voltage 12V to 24V system. Applicable standards: JIS C 0023-Basic environmental testing procedures pare 2:test-test ka: salt mist JIS C 0044-Basic environmental testing procedures pare 2:test-test ed: free fail JIS C 0912 -Shock testing procedure for electric machines and equipment JIS C 1102-Electric indicating instruments JIS D 0203-Method of moisture, rain and spray test for automobile parts JIS D 0207-General rules of dust test for automobile parts JIS D 1601-Vibration testing method for automobile parts JIS K 6301-physical testing methods for vulcanized rubber JIS Z 8703-Standard atmospheric conditions for testing JIS Z 8901-Dusts and aerosols for industrial testing 2. Definitions Definitions of major terms used in this standard are as follows: (1) Automotive electronic equipment The general term for electronic device and system including electric/electronic sensors , control units (or computers),displays ,audio-visual devices,etc.having structures and shapes that can be installed on the automobile. (2) Normal power supply voltage Power supply voltages within a voltage range in which an equipment should maintain its performance normally. (3) Abnormal power supply voltage Any power supply voltage outside of the normal power supply voltage range, which is impressed temporarily on the equipment, due to the reversed connection of battery, failure of voltage regulator, jumper-start under the cold ...
