GDJS/GDJW High and Low Temperature Humidity Chamber is Designed According to IEC 60068-2-1 Environmental Testing Part 2-1: Tests-Test A: Cold

The full name of IEC 60068-2-1 is Environmental Testing Part 2-1: Tests-Test A: Cold. It is edited by the IEC technical committee in 2008.We will introduce the IEC 60068-2-1 Environmental Testing Part 2-1: Tests-Test A: Cold
The following is the original content of IEC 60068-2-1
IEC 60068-2-1 Environmental Testing Part 2-1: Tests-Test A: Cold
This part of IEC 60068 deal with cold tests applicalbe to both non heat-dissipating and heat-dissipating specimens. For non heat-dissipating specimens, Tests Ab do not deviate essentially from earlier issues. 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, equioment 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 60068-2-14.
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, Ae.
The procedures given is this standard are normally intended for specimens that achieve temperature stability during the performance of the test procedure.
LISUN designed the GDJS/GDJW High and Low Temperature Humidity Chamber according to the IEC 60068-2-1 standard. It is used to test the CFL/LED which meets IES LM-80-08, electricity products, electronic components, material and so on. We will update the procedure and testing parameters according to the updating of the IEC 60068 standard.
