Summary: This standard specifies the recommended environmental testing, in order to prove that the products have the ability to withstand the GB/T 4798 with climatic and mechanical environmental conditions can choose these trials, including the severity of experimental test cycle is not recommended in order to prove the reliability of products, the corresponding guidelines should suitability, reliability -related publications choice. Impossible for all products, sites and applications are recommended test severities, but can be recommended for most cases test severities. Guidelines are given in the recommended test severities is how to choose the. When the GB/T 4798 series of standards sufficient to describe some of the specific environmental conditions or application, the Guide contains the same principle can be used to modify the test severities.
