- Cold tests for non heat-dissipating specimens: * with gradual change of temperature, Ab;
- Cold test for heat-dissipating specimens: * with gradual change of temperature, Ad,
* with gradual change of temperature, specimen powered throughout, Ae.
The procedures given in this standard are normally intended for specimens that achieve temperature stability during the performance of the test procedure. Temperature chamber(s) are constructed and verified in accordance with specifications IEC 60068-3-5 and IEC 60068-3-7. Further guidance for dry heat and cold tests can be found in IEC 60068-3-1 and general guidance in IEC 60068-1. This sixth edition deals with cold tests applicable both to non heat-dissipating and heat-dissipating specimens. For non heat-dissipating specimens, Tests Ab and Ad do not deviate essentially from earlier issues. Test Ae has been added primary for testing equipment that requires being operational throughout the test including the conditioning periods. It has the status of a horizontal standard in accordance with IEC Guide 104
