When discussing the water resistance of electronic products, we often encounter various water resistance standards. Among them, the IPX56 rain test chamber and IP44 water resistance are two common water resistance testing standards.
With the rapid development of China's industry, an increasing number of sectors require high and low temperature test chambers for product testing. The market offers numerous brands with varying prices and similar technical parameters.
Salt-spray corrosion testing is one of the most frequently used and fastest accelerated methods for evaluating the corrosion resistance of materials and their protective coatings. In a test chamber a salt solution is atomized by compressed air into a uniform fog that is continuously or intermittently sprayed onto specimens in a sealed, temperature- and humidity-controlled space.
A constant temperature and humidity test chamber consists of multiple components, and any malfunction can disrupt testing. Previously, we discussed troubleshooting methods for other issues. Today, we focus on expansion valve failures.
The thermal shock test chamber is a cornerstone of environmental-reliability testing. Within tens of seconds it transfers specimens between extreme high- and low-temperature zones, revealing mechanical stress, electrical degradation, and chemical instability induced by rapid thermal expansion and contraction.
