introduction
When under different environmental conditions, there is no significant degradation in the performance of the specified equipment and components.
The type and severity of the environment in which the equipment and components are tested depends on the work, transportation and storage environment. The impact of the environment on the equipment is hot
The belt, subtropical region and the Arctic region are completely different. Individual parameters can cause large variations or overlapping effects on devices and components.
Both manufacturers and users want equipment and components to withstand the various environments in which the product is exposed. In order to get in a relatively short period of time
Obvious results, by increasing the severity of environmental conditions, you can expose the sample to a certain level in the laboratory in a short period of time.
Evaluate under ambient environmental conditions. Therefore, it is possible to estimate a near-real test effect by applying similar environmental conditions.
Especially in the automotive, rail transit and aerospace sectors, there is a comprehensive environment of temperature, humidity and vibration.
Environmental testing - Part 2. Tests and guidelines
Climate (temperature, humidity) and dynamics (vibration, shock)
Comprehensive test
1 Scope
This part of GB/T 2423 provides methods and guidelines for the comprehensive testing of climate and dynamics of equipment or components.
The purpose of the comprehensive test is to investigate the extent to which equipment or components are affected by a comprehensive climate and kinetic test.
This comprehensive test method is suitable for inspecting electrical, mechanical or other physical changes.
