What is Severity Test A and B for ASSEMBLY ?

Severity Test for Assembly is Degree of impact a defect has on its operation, under conditions of high humidity combined with cyclic changes in temperature.

Severity Test for Assembly is defined as the Degree of impact a defect has on the operation of Assembly, under conditions of high humidity combined with cyclic changes in temperature.

The temperature and humidity cycles typically produce condensation on the internal or external surface of ASSEMBLY.

The resistance to corrosion of ferrous metallic enclosures including internal and external ferrous metallic constructional parts of the ASSEMBLY is to be verified, There are two test methods : Severity tests A and B, As defined in IEC60068-2-30.

  • Severity test A applies to indoor installations.
  • Severity test B to outdoor installations.
