When anomalies occur during operation, on-site personnel are advised to follow the four-step troubleshooting method “Symptom – Cause – Action – Verification.” Typical faults and their countermeasures are presented below for quick reference.

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.

The high-low temperature test chamber is a cornerstone of environmental-reliability verification. Its mission is to reproduce extreme temperature and humidity conditions in a controlled manner so that performance degradation and failure modes of the Device Under Test (DUT) can be assessed across its life cycle.

Dust/sand test chambers are environmental simulation devices designed and manufactured in accordance with GB/T 2423.37, IEC 60068-2-68, ISO 20653 and other international standards. They are used to evaluate the sealing reliability and corrosion resistance of locks, automotive/motorcycle parts, seals, power meters and other products under sandstorm conditions.

The thermal shock chamber (TSC) is a cornerstone instrument in environmental-reliability testing. By exposing a specimen to rapid alternations between extremely high and extremely low temperatures, it reproduces the severe thermal excursions encountered during service or transport.

Thermal shock test chambers, renowned for their outstanding stability and reliability, are extensively employed in the testing of automation components, telecommunications equipment, plastics, aerospace hardware, chemical materials, LEDs, and electronic devices.

To ensure that all salt spray test chambers remain in optimal operating condition, deliver accurate test data and achieve maximum service life, this work instruction is established. Scope

Low-temperature test chambers are dedicated to evaluating the storage reliability and environmental adaptability of electronic and electrical products, automotive components, household appliances, and related materials in extreme cold climates.

UV weathering test chambers are typically equipped with either UVA-340 or UVB-313 cold-cathode fluorescent UV lamps. The spectral differences between the two types directly influence the acceleration factor and the reliability of test results.

Following our previous discussion on the effects of high-temperature environmental testing, this paper systematically summarizes the typical property changes that occur in test specimens within low-temperature test chambers (hereinafter referred to as “the equipment”).
