The Necessity of Lightning Protection and Performance Advantages of Low-Temperature Test Chambers

Low-temperature test chambers are primarily used to evaluate the storage capabilities and environmental adaptability of products and materials from industries such as electronics, electrical engineering, automotive, and home appliances under extremely low-temperature climatic conditions.

How the cryogenic test chamber achieves a stable low-temperature environment

Cold and thermal shock test chamber on the market is divided into two categories, a two-compartment type, including high-temperature region and low-temperature region, the test object were tested in two different temperatures in the area of the test, alternating hot and cold test; the other is a three-compartment type, in addition to high-temperature and low-temperature areas, there is also a test area, and the difference between the two-compartment is that the three-compartment type does not need to be tested directly in the test area.

Technical Analysis of Simulated-Environment Test Procedures in Rain Test Chambers –– A Comprehensive Overview Based on IEC 60068-2-18, ISO 20653 and Major OEM Standards

With the continuous tightening of ingress-protection requirements in automotive electronics, low-voltage power distribution and photovoltaic industries, repeatable, quantifiable and traceable artificial-rain testing has replaced the traditional “splash-and-inspect” approach and become the core means of verifying sealing performance.
