Environmental test chambers, such as constant temperature and humidity testing equipment, are essential tools used to simulate the natural environmental factors that exist on Earth's surface and in the atmosphere. These factors include temperature, humidity, pressure, radiation, and many others. The exact number of environmental factors is difficult to determine, as there are dozens that significantly affect the performance and lifespan of engineering products. Engineers working in the field of product environmental conditions classify these natural and human-induced factors into standardized test procedures and specifications. These standards serve as a guide for conducting environmental and reliability tests on engineering products.
To ensure consistency and accuracy in testing, national technical supervision agencies and various industrial sectors have also developed verification procedures for environmental test equipment. For example, China’s national standard GB5170 outlines the basic parameters for verifying environmental test equipment used in electrical and electronic products. Additionally, the National Technical Supervision Bureau has issued regulations like JJG190-89, which provide guidelines for the verification of electric vibration test benches. These procedures are crucial when selecting environmental and reliability test equipment, as any device not meeting these requirements cannot be used in official testing environments.
When choosing environmental and reliability test equipment, it's important to follow certain key principles. First, the environmental conditions must be reproducible. Second, the parameters of the environmental conditions should be measurable and controllable. Third, the test conditions should be exclusive—meaning they should accurately simulate the intended environment without interference. Finally, the equipment itself must be safe and reliable to ensure accurate and consistent results.
