The inspection methods given in GB/T 5170.18 are mainly used for the inspection of the test equipment used in GB/T 2423.34.Combined temperature/humidity cycle The ring test includes damp heat and low temperature tests. The reason this combination test is more severe than other damp heat cycle tests is that in a given time There are more temperature changes; the temperature cycle changes in a larger range and at a higher rate; it also contains multiple temperature changes below 0 °C. element The purpose of the combined temperature/humidity cyclic testing of individual products is to determine in an accelerated manner the degradation of these products under high temperature/humidity and low temperature conditions Tolerance under action. The combined temperature/humidity cycle test is not interchangeable with the constant damp heat test or the alternating damp heat test. whatever this Whether the combination test is carried out in one test chamber or two test chambers, the test chambers used shall meet the requirements of GB/T 2423.34. This document is consistent with international standards and is conducive to eliminating technical barriers to trade and promoting international trade.
