Environmental test is to simulate real environmental conditions or reproduce the influence of environmental conditions to prove to a certain extent that the product remains intact and works normally under specific environmental conditions.Of products mainly include: the influence of thermal aging, softening melting sublimation, expansion, embrittlement, reduction, physical contraction of mechanical strength, moisture absorption or adsorption, chemical reaction, corrosion, increasing the conductivity of the insulation, resulting in cracking products, insulation damage, physical damage, mechanical failure, increasing the mechanical stress and so on.
The following items are involved:
Cold test GB/T 2423.1 IEC 60068-2-1 EN 60068-2-1IEC 60068-2-2 EN 60068-2-2Constant heat and humidity (constant temperature and humidity) GB/T 2423.3 IEC 60068-2-78 EN 60068-2-78Alternating damp heat GB/T 2423.4 IEC 60068-2-30 EN 60068-2-30Temperature change (rapid temperature change) GB/T 2423.22 IEC 60068-2-14 EN 60068-2-14Temperature/humidity combined cycle test GB/T 2423.34 IEC 60068-2-38 EN 60068-2-38
