IEC 60068-2-14 Change of Temperature Testing

IEC 60068-2-14 Temperature Testing

IEC 60068-2-14 determines the ability of components to withstand rapid changes to temperature. As an ISTA and ISO 17025 certified lab, we realize the importance of IEC 60068 testing. Meeting the IEC temperature requirements can be difficult. We understand the challenges and guide companies through the process.

Keystone Compliance has a reputation for helping customers achieve their package certifications. When packages do not meet the requirements, we assist with finding solutions. We provide comprehensive reports shortly after the completion of the testing. Our proven process helps avoid product launch delays.

IEC 60068-2-14 Change of Temperature Testing

IEC 60068-2-14 testing also called the change of temperature test, is intended to determine the ability of components, equipment, and other items to withstand a change of temperature or a succession of changes of temperature.

It is common in electronic equipment that changes of temperature occur. Parts inside the equipment may undergo slower changes than those on an external surface. Change of temperature testing is recommended when evaluating electrical performance during a change in temperature. This test is also recommended for evaluating the suitability of the construction of components to withstand artificial stressing.

The IEC 60068-2-14 integrity standard is not intended to show effects that are due only to high or low temperatures. Testing to those conditions is specified in the following related standards:

  • IEC 60068-2-1, Environmental testing – Part 2-1: Tests – Test A: Cold
  • IEC 60068-2-2, Environmental testing – Part 2-2: Tests – Test B: Dry heat
  • IEC 60068-2-17, Environmental testing – Part 2-17: Tests – Test Q: Sealing

IEC 60068-2-14 testing is important because of how often rapid changes in temperature can occur. Events such as equipment being transported from warm indoor environments into cold open air conditions or vice versa, equipment being suddenly cooled by rainfall or immersion in cold water, equipment being externally mounted airborne and under certain conditions of transportation and storage.

Components will undergo stress due to changing temperature when high-temperature gradients build up in equipment after being switched on, e.g. in the neighborhood of high wattage resistors. Radiation can cause a rise in surface temperature in neighboring components while other portions are still cool.

IEC-60068-2-14 specifies the number of effects from the testing including but not limited to:

  • Values of high and low conditioning temperature between which the change is to be effected.
  • The conditioning times for which the test specimen is kept at these temperatures.
  • The rate of change between these temperatures.
  • The number of cycles of conditioning.
  • The amount of heat transferred into or from the specimen.

Expert IEC Change in Temperature Testing

Keystone Compliance strives to give our customers more time and energy on product development instead of testing. We can accommodate flexible and rigid packages of all sizes, including large pallets. Keystone has a full lab of test equipment which permits us to provide short lead times on scheduling.
