GB/T 7288.2-1987

This standard specifies preferred test conditions for reliability testing of equipment designed for stationary use in weather-protected locations, such as indoor industrial machinery or control cabinets. It is applied in manufacturing and quality assurance contexts to simulate high-accuracy environmental stresses (e.g., temperature and humidity) for verifying long-term performance and failure rates. The standard is particularly relevant for engineers conducting accelerated life tests on non-portable electronic or electrical systems in controlled indoor settings.
