Recently, our company's technical department, through close communication and coordination with the scientific research team of Xi'an Jiaotong University, has gained a deep understanding of their environmental testing needs and challenges.
A sand and dust test chamber is a testing device used to inspect the sealing performance of products. However, if the equipment is not installed correctly before use, various issues may arise during its operation, leading to inaccuracies in the test results.
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.
Most temperature cycling test chambers on the market feature an inner chamber made of stainless steel. However, after prolonged use, rust may still appear on the equipment. Why does this happen, and are there effective ways to prevent it?
