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.

What Are the Differences in Performance of Different High and Low Temperature Alternating Test Chambers?

The primary purpose of high and low temperature alternating test chambers is to assess the adaptability of products and determine their performance under various environmental conditions

Salt Fog Test Chamber – Specification for Corrosion Resistance Evaluation

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.
