Industry News

Sand and Dust Test Chamber – Code of Practice and Key Technical Details (Conforming to GB/T 2423.37, GB 4208, IEC 60529, ISO 20653, etc.)

A sand and dust test chamber is the core item of equipment used to simulate desert, arid and industrial high-dust environments. The quality of its operation directly determines a product’s IP protection rating, reliability life and market-access qualification.

How to Resolve Unstable Low Temperatures in High and Low Temperature Alternating Test Chambers

Regularly, staff should master some troubleshooting and handling methods for high and low temperature alternating test chambers. If the equipment exhibits unstable low temperatures, what causes this phenomenon, and how should we address these faults?

Standardized Operating Instruction for Constant Temperature and Humidity Test Chambers (Applicable to R&D, Quality Inspection, and Third-Party Laboratories)

To ensure the electrical, mechanical and thermodynamic integrity of constant temperature and humidity test chambers (hereafter “the chamber”), to standardize operating procedures, and to reduce failure and accident rates, this instruction is established. It applies to all programmable, single-point and walk-in chambers that are newly purchased, in service or relocated.
