The International Organization for Standardization (ISO) provides detailed standards in the ISO 16750 series for environmental conditions and tests for automotive electrical and electronic systems. These standards describe conditions and test methods for electrical and electronic systems in road vehicles. The series includes sections and general notes, excluding requirements for electromagnetic compatibility (EMC).

Essentially, ISO 16750 standard “Road vehicles – Environmental conditions and testing for electrical and electronic equipment” consists of the following standards under the main heading:

ISO 16750-1 Part 1: General
ISO 16750-2 Part 2: Electrical loads
ISO 16750-3 Part 3: Mechanical loads
ISO 16750-4 Part 4: Climatic loads
ISO 16750-5 Part 5: Chemical loads

The development of this standard series considers the following activities:

World geography and climate
Vehicle production
Vehicle usage conditions and operating modes
Lifetime energy
Vehicle power supply voltage
Mounting location in the vehicle
