Description:

The rapid temperature change test is conducted to evaluate the adaptability of a product to rapid temperature fluctuations in storage, transportation, and usage under varying climatic conditions. The test procedure typically follows a cycle of ambient temperature → low temperature → low-temperature dwell time → high temperature → high-temperature dwell time → ambient temperature. It aims to assess the functional characteristics and operational functionality of the sample after exposure to temperature changes or continuous temperature variations.

The rapid temperature change test is usually defined with a temperature change rate of ≥3℃/min, transitioning between predefined high and low temperatures. A faster temperature change rate, wider range of high/low temperatures, and longer test duration indicate stricter testing conditions. Temperature shocks generally have a greater impact on areas closer to the equipment’s outer surface, with less significant effects as the distance from the surface increases. The influence of temperature changes on enclosed equipment is mitigated by transportation boxes, packaging, and similar measures. Drastic temperature fluctuations may temporarily or permanently affect the operation of the equipment.

Purpose: to assess the storage and operational adaptability of a product under temperature variation conditions. Qualification tests are conducted to determine if the product meets relevant standards, while improvement tests primarily evaluate the durability and reliability adaptability of the product to temperature changes.

Scope of Application :

Widely used in electrical and electronic, vehicles, medical, instrumentation, petrochemical and other fields, the whole machine, components, packaging, materials and so on.
