The object of this standard 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.

Temperature & humidity testing determines how components, subsystems and complete systems behave in severe environments that involve elevated temperatures and high or fluctuating relative humidity. The tests can be static with constant temperature and humidity, they can involve the cycling of both, and they can be temperature-humidity bias tests or some combination of all of these.

Industrial standards that administrate the Temperature & Humidity Test are:

• IEC 60068-2-78:2012 Test Cab: Damp Heat, Steady State
• IEC60068-2-30 Ed3:2005
• JESD22-A101D:2015
• MIL-STD-883G
