GB/T 2424.7-2006 Environmental tests for electric and electronic products - Measurements in temperature chambers for tests A and tests B (with load) (English Version)
1 Scope
This part of GB/T 2424 provides a uniform and reproducible method of confirming that temperature test chambers conform to the requirements specified in climatic test procedures of GB/T 2423.1 and GB/T 2423.2, when loaded with either heat-dissipating or non heat-dissipating specimens under conditions which take into account air circulation inside the working space of the chamber. This standard is destined primarily for users when conducting regular chamber performance monitoring.
