Scope

The high temperature test described in this standard is applicable to both heat dissipation and non-heat dissipation test samples. For non-heat dissipation test samples, tests Ba and Bb do not substantially deviate from earlier published standards. The purpose of this high-temperature test is limited to determining the suitability of components, equipment or other products for use or storage under high-temperature environmental conditions. This high temperature test cannot be used to evaluate the resistance of the test sample to temperature changes and the ability to work during temperature changes. In this case, Test N: Temperature change test method should be used. The high-temperature test method is divided into: High-temperature test for non-radiation test samples: - Test Ba: sudden temperature change; - Test Bb: gradual temperature change. Heat dissipation test sample high-temperature test: ——Test Bc: sudden change in temperature; ——Test Bd: gradual temperature change. , this test method is generally used for test samples that achieve temperature stabilization during the conditioning test. The test duration is calculated from the time when the temperature of the test sample has stabilized. In special cases, if the test sample does not reach a stable temperature during the conditional test, the test duration shall be calculated from the time when the test chamber (chamber) reaches the specified test temperature. Relevant specifications should stipulate: a) The rate of temperature change in the test chamber (chamber); b) The time when the test sample is placed in the test chamber (chamber); c) The time when the test sample is exposed to the test conditions; d) The test sample is powered on or load time. For these situations, the makers of the relevant specifications can select the above 4 parameters according to the GB/T 2424.1-1989 guidelines (amendments including the above situations are under consideration).
