Salt-spray cabinets artificially intensify corrosive agents so that months or even years of marine or industrial atmospheric attack are reproduced within a few hours or days. This paper systematically describes the working mechanism of the equipment, the control logic of its critical parameters, and the quantitative correspondence between test results and natural exposure. The aim is to provide industry with the technical basis for tailoring test programmes to specific products.

Most metal corrosion occurs in the atmospheric environment, which contains corrosive components and factors such as oxygen, humidity, temperature changes, and pollutants. Salt spray corrosion is a common and highly destructive form of atmospheric corrosion.

There are many important considerations when selecting and using a formaldehyde/VOC environmental test chamber. How many of these are you aware of? Today, we’ll share a few key points—have you noticed them?

Salt fog (salt spray) test chambers are standardized instruments designed to determine the corrosion resistance of materials and their protective coatings. The test results serve as a technical basis for reliability design, quality control, and service-life prediction in industries such as electrical and electronic engineering, digital components, plastics, aerospace equipment, and many others.

Thermal vacuum testing is a type of test that verifies the performance and functionality of spacecraft and its components under vacuum and specific temperature conditions.
