IEC60068-2-30 Environmental testing – damp heat cyclic
IEC60068-2-30
IEC 60068-2-30 focuses on environmental testing specifically deals with damp heat tests for electronic components and equipment.
To determine the ability of components, equipment, or other articles to withstand conditions of high humidity combined with cyclic temperature changes, which can produce condensation on the surface of the specimen.
The test involves exposing the specimen to a cycle of high humidity (up to 95% relative humidity) and temperature (usually between 25°C and 55°C) for a specified period, followed by a period of lower humidity and temperature. This cycle is repeated for the number of times specified by the test parameters.
IEC60068-2-38 Envtest – Composite temperature/HUMIDITY CYC
IEC60068-2-38
IEC 60068-2-38 focuses on environmental testing specifically deals with composite temperature/humidity cyclic tests for electronic components and equipment.
To determine the resistance of specimens to the deteriorative effects of high temperature/humidity and cold conditions in an accelerated manner.
The test involves exposing specimens to cycles of high humidity (up to 95% relative humidity) and temperature (usually between 25°C and 65°C), followed by lower humidity and temperature. the temperature can be maintained at –10 °C for cold. This cycle is repeated for a specified number of times.
IEC60068-2-67 Damp heat, steady state, accelerated test
IEC60068-2-67
IEC 60068-2-67 focuses on environmental testing specifically deals with damp heat tests for electronic components and equipment.
To evaluate the resistance of small electrotechnical products, primarily non-hermetically sealed components, to the deteriorative effects of damp heat in an accelerated manner.
The test provides a number of preferred durations at a relative humidity of 85 % and a temperature of 85 °C.
IEC60068-2-78 Damp heat, steady state
IEC60068-2-78
IEC 60068-2-78 focuses on environmental testing specifically deals with damp heat tests for electronic components and equipment.
To determine the ability of components or equipment to withstand transportation, storage, and use under conditions of high humidity.
The test involves exposing the specimen to high humidity (up to 95% relative humidity) at a constant temperature without condensation for a specified period.
