If a salt spray test chamber is used for a long time without cleaning, dust will inevitably accumulate both inside and outside the equipment.

A high-temperature test chamber simulates extreme heat environments to evaluate the performance and parameters of various materials or products under such conditions.

A low-temperature test chamber is a device used to test the cold resistance of electronic components or special materials.

Previously, we introduced some common problems with high and low temperature test chambers. Today, we will discuss the issue of slow cooling in the test equipment, which may be caused by malfunctions in the refrigeration system.

Dust testing, codified in GB/T 2423.37 and IEC 60068-2-68, is now mandatory for proving the sealing integrity and reliability of military, automotive, photovoltaic and rail-transit products. Direct test outlays—consumables, energy, labour and depreciation—seldom exceed one to three per cent of the selling price, yet hidden expenses triggered by poor chamber selection—repeat tests, invalid data or after-sales downtime—can leap to eight to twelve per cent.
