IEC 60068-2-2 Environmental Testing: Dry Heat

IEC 60068-2-2 testing determines the ability of heat-dissipating and non-heat-dissipating specimens to withstand conditions of dry heat. Specifically, the goal of the dry heat test is limited to the determination of the ability of components,

equipment or other articles to be used, transported or stored at high temperature. A specimen is considered heat-dissipating only if the hottest point on its surface, measured in free air conditions (i.e. low air velocity circulation), is more than 5 K above the ambient temperature of the surrounding atmosphere after temperature stability has been reached.

IEC-60068-2-2 testing occurs by having the unit under test introduced into the chamber, which is at the ambient temperature of the laboratory. The temperature is then adjusted to the temperature appropriate to the degree of severity as

specified in the relevant specification. After temperature stability of the test specimen has been reached, the specimen is exposed to these conditions for the specified duration. For specimens that are required to be operational (even though they do not meet the requirements of being heat dissipating) power shall then be applied to the specimen and a functional test is performed as necessary. A further period of stabilization may be necessary and the specimen shall then be exposed to the high temperature conditions.

Keystone Compliance has a full climatics lab with several temperature/humidity chambers including small reach-in chambers and chambers capable of testing entire cars. The lab also contains thermal shock chambers and a number of other testing equipment such as shakers, altitude chambers, shock machines and ingress protection equipment.
