Salt fog (salt spray) chambers are indispensable for evaluating the corrosion resistance of materials and coatings in automotive, aerospace, electronics, hardware, coatings and defense industries.

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.

Some companies use salt spray test chambers very frequently, and long-term use inevitably leads to malfunctions.

A constant temperature and humidity test chamber can regulate temperature and humidity according to different testing requirements for products.

To ensure that all salt spray test chambers remain in optimal operating condition, deliver accurate test data and achieve maximum service life, this work instruction is established. Scope
