Why do so many industries rely on salt spray test chambers? Because many manufactured products need to be tested for their resistance to salt spray corrosion. However, relying solely on natural atmospheric conditions for testing could take years or even decades.

A salt spray test chamber is an artificial environmental simulation device used to test the corrosion resistance of products. It evaluates the degree of corrosion on materials or products by exposing them to a simulated salt spray environment.

A thermal-shock chamber (TSC) is not an off-the-shelf climatic box. Its only purpose is to generate controlled temperature gradients and rapid transfer rates that reveal thermo-mechanical defects. A poor choice will distort test data, delay R&D, fail certification audits, or even trigger a product recall. This paper translates field experience into an engineering checklist for R&D, Quality and ESS engineers.
