Environmental testing - Part 2: Testing method - Test Cab: Damp heat, steady state
1 Scope
This part of GB/T 2423 establishes a test method for determining the ability of components or equipment to withstand transportation, storage and use under conditions of high humidity.
The object of this part is to investigate the effect of high humidity at constant temperature without condensation on a specimen over a prescribed period.
It is applicable to small equipment or components as well as large equipment, and can be applied to both heat-dissipating and non-heat-dissipating specimens.
