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.
Cold tests cover by this standard do not enable the ability of
specimens to withstand or operate during the temperature variations
to be assessed. In this case, it would be necessary to use IEC
The cold tests are subdivided as follows:
- 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,
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.
