Cold and hot shock test chambers utilize high-temperature and low-temperature zones during testing. In the testing process, two-box models involve placing the test product in high and low-temperature zones for cyclic exposure, while three-box models involve blowing high- and low-temperature gases onto the product alternately.

With the continuous updating of GB/T 4208-2017, IEC 60529:2013, MIL-STD-810H and other domestic and international protection-class standards, “rain testing” has evolved from a simple “water-proof check” into a systematic evaluation covering sealing reliability, material weatherability, structural integrity, electronic compatibility and more.

Rain test chambers are used to evaluate the waterproofing parameters and performance of automotive components, low-voltage electrical enclosures, and other products. These devices simulate relevant environmental conditions for testing.

The refrigeration compressor is one of the core components of a high/low-temperature test chamber, and its selection is closely related to the test results. In fact, semi-hermetic compressors are commonly used in these chambers. Why is this the case? Today, we will explore the three main reasons.

The salt fog chamber is the core instrument for evaluating the corrosion resistance of materials and protective coatings. Its measurement repeatability and reproducibility are directly affected by installation quality.
