Introduction

GB/T 2423 series of standards include basic information on environmental tests and their severity levels, which are used to evaluate the performance of test samples under the expected storage conditions.

In this series of standards, each document introduces a set of tests and applications.

The GB/T 2423 series of standards aims to provide product specification developers and product testers with a series of unified and repeatable climatic, mechanical and comprehensive It includes standard atmospheric conditions for measurement and testing.

Since 1981, more than 50 GB/T 2423 series standards have been issued and implemented. There are 52 GB/T 2423 standards in existence, 42 of which are Items adopt the IEC 60068-2 series of standards. For details of the current GB/T 2423 series of standards, please see Appendix A.

4 General description of the test

This test is a comprehensive environmental test consisting of temperature and humidity climate conditions and static load mechanical environmental conditions.

The temperature test includes low temperature, high temperature and constant humidity and heat, etc. The specific test methods can be found in the relevant parts of the GB/T 2423 series of standards or relevant specifications.

Static loads include tension, compression and bending. The type and size of static loads are related to the loads to which the test specimen is subjected in service.

According to the service environment conditions of the test sample, select the corresponding temperature, humidity climate environment conditions and static load mechanical environment conditions to test the test sample.

Table 1 shows some combinations of temperature, humidity and static load comprehensive environmental tests.
