To meet various market demands, many types of testing chambers have been developed, among which the salt spray test chamber is one of the most common.

Thermal shock test chambers, as precision testing equipment, rely heavily on compressed air for their stable operation. Regardless of the chamber's structural design, compressed air serves as a critical component in driving rapid temperature transitions and ensuring precise temperature control within the test zone.

Analyzing the causes of equipment failures in high-temperature test chambers can help resolve issues more quickly.

The operation of the sand and dust test chamber primarily involves using a fan to blow sand and dust of the required concentration at an appropriate flow rate over the surface of the test sample.

In generic reliability standards such as GB/T 2423, IEC 60068 and MIL-STD-810, “damp heat” is treated as an independent climatic stress. The goal is not merely to verify moisture resistance, but to accelerate and expose failure modes triggered by water adsorption, condensation, “breathing” and electrochemical migration.
