This test is used to determine the adaptability of the product to storage, transportation and use under the climatic environment with rapid or slow changes in high temperature and low temperature. The test process is a cycle of normal temperature → low temperature → low temperature retention → high temperature retention → normal temperature. The severity of temperature cycle test is determined by the high/low temperature range, retention time and number of cycles. The reference test standards are GB/T2423.34, IEC60068-2-38, GB150.5, etc
