Scope
This standard specifies the comprehensive test purpose, test equipment, severity level and test procedures of low temperature (gradual temperature change and abrupt change) and low air pressure test samples for heat dissipation and non-heat dissipation test samples. The comprehensive test specified in this standard is usually only used when the single environmental test of the test sample cannot reveal the comprehensive environmental impact. The test methods specified in this standard are only applicable to test samples that can achieve temperature stability during the test. The test method specified in this standard can only test one heat dissipation test sample at a time, and the heat dissipation test sample should generally be carried out in a test box without forced air circulation according to the provisions of GB 2423.1. This standard is only applicable to pressure tests with air pressure greater than 1kPa. See GB 1920 for the relationship between altitude, pressure and temperature. The guidance in GB 2423.1 on the application comparison of non-heat dissipation test sample test and heat dissipation test sample test is also applicable to this standard. Note: The definition of non-radiation test samples is in accordance with the provisions in GB 2422, and the temperature of hot spots should not be measured under low pressure.
