Low temperature test chambers serve as critical equipment for material low-temperature performance verification, electronic component reliability testing, and biological sample preservation.

As the core functional unit of salt spray test chambers, temperature control directly determines the reliability of salt spray environment simulation and the reproducibility of test results.

High-low temperature test chambers reproduce a product’ […]

Thermal-Shock Chambers (TSCs) impose severe temperature ramps (?70 °C ? +200 °C within ≤5 min). Superimposed mechanical and thermal stresses exponentially raise failure rates.

The Dust Test Chamber is the key apparatus for verifying enclosure protection ratings (IP5X, IP6X) and sealing integrity. Its results directly determine whether a product can survive long-term exposure to deserts, mining areas or other dust-laden environments.

Salt-spray corrosion testing is the core means of evaluating the resistance of materials and their protective coatings to chloride-containing environments. The test itself only provides an accelerated corrosion “stimulus”; the real technical value lies in the scientific evaluation of the test results.

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.

Salt-spray cabinets artificially intensify corrosive agents so that months or even years of marine or industrial atmospheric attack are reproduced within a few hours or days. This paper systematically describes the working mechanism of the equipment, the control logic of its critical parameters, and the quantitative correspondence between test results and natural exposure. The aim is to provide industry with the technical basis for tailoring test programmes to specific products.

In the aerospace, automotive, home-appliance and materials-science sectors, products must routinely undergo prolonged and repeatable exposure within the ?80 °C to 0 °C range to verify functional integrity and service life under extreme cold. Nature cannot supply a continuous, controllable and stable sub-zero environment; consequently, low-temperature test chambers are employed to create an artificial cryogenic duty.

With the continuous updating of GB/T 4208-2017, IEC 60529:2013, MIL-STD-810H and other domestic and international protection-class standards, “rain testing” has evolved from a simple “water-proof check” into a systematic evaluation covering sealing reliability, material weatherability, structural integrity, electronic compatibility and more.
