Scope

This Part of GB/T 2423 deals with cold tests applicable to both non heat-dissipating
and heat-dissipating specimens. Test Ab and test Ad have no significant difference
with that of previous version1). Test Ae has been added primarily for testing equipment
that requires being operational throughout the test, including the conditioning periods.
The object of the cold test is limited to the determination of the ability of components,
equipment or other articles to be used, transported or stored at low temperature.

Summary	This standard specifies the low temperature test for non- thermal and thermal test samples. Ab test and test Ad with earlier versions no substantive difference, increasing test Ae main purpose is to detect those requirements throughout the trial process, including cooling adjustment period should run power equipment. The purpose of this test is limited to low temperature is used to determine components, equipment, or other products used in low temperature environment, transport or storage capacity. The low temperature test can be used to evaluate the test sample capacity and resistant to temperature changes in the operating environment temperature capability, in this case, should be adopted GB/T 2423. 22. The low temperature test method subdivided into the following categories: Non- heat test sample temperature test: �� Test Ab, the temperature gradient. Thermal test sample temperature test
