Change of Temperature Test Specification

Change of Temperature Test

The Change of Temperature Test assesses the performance and reliability of electrical and electronic equipment when subjected to rapid temperature changes. The test aims to determine if the equipment can function without significant damage or performance issues under such conditions, which can be encountered during transportation, startup, or other real-world scenarios.

  • This test is pertinent to an extensive variety of electrical and electronic hardware utilized in different businesses, including yet not restricted to broadcast communications, car, aviation, and modern applications.
  • The standard specifies the conditions and procedures for conducting the test, including the rate of temperature change, the temperature range, and any required preconditioning steps. The equipment is typically placed in a test chamber where the temperature is rapidly cycled in a controlled and repetitive manner.
  • Performance Criteria: The equipment is evaluated both during and after the test to ensure that it does not suffer significant degradation or damage and continues to function as intended. The acceptance criteria that the equipment must meet to pass the test are outlined in the standard.
  • The Change of Temperature IEC BS EN 60068-2-14 is a standard that specifies test procedures and test levels.
