lithium battery temperature humidity test Principles and Standards.Temperature and humidity reliability testing is critical to verifying battery durability, ensuring compliance with global standards (UL 1642, IEC 62660, UN 38.3), and reducing field failure risks for manufacturers.

Industry-specific guide for U.S. manufacturers: Environmental test chambers tailored for electronics, automotive components, and EV batteries. Learn performance standards, safety features, and compliance requirements to meet U.S. regulatory and industry demands.

A clear comparison of benchtop, floor-standing, and walk-in environmental test chambers. Help U.S. labs and manufacturers choose the right style based on sample size, testing needs, lab space, and budget.

Avoid expensive errors when purchasing an environmental test chamber. This article outlines the most common mistakes U.S. buyers make, including poor sizing, ignored uniformity, high energy costs, and missing industry compliance.

When evaluating corrosion resistance for metal parts, coatings and fasteners, ASTM B117, ASTM G85 and ASTM 8117 are three of the most widely used international test standards. Each standard simulates different environmental conditions and serves distinct testing purposes. Understanding their differences helps you select the most suitable corrosion test chamber for your product and industry requirements.
