Why this test matters

Corrosion is one of the main causes of product failure in metal parts and coated surfaces. The salt spray test shows how well your coatings, surface treatments, or materials resist harsh environments, using an accelerated setup that compresses months or years of real-world exposure into a controlled test period. It's essential for manufacturers in sectors such as automotive, construction, marine, and hardware, where corrosion can quickly affect both performance and appearance.

How the test works

Your samples, up to 20 kg, are placed in a salt spray cabinet and exposed to a fine mist of neutral salt solution at an elevated temperature, with cut edges coated beforehand so they don't skew the result. The test runs for a set period, anywhere from 1 hour up to 10,000 hours depending on your standard or requirement, while we check the evolution of corrosion at regular intervals throughout. We can test coated or uncoated material, and undamaged or deliberately scratched samples, so you can see not just how a coating resists corrosion but how far it spreads once the coating is compromised.

What you learn from this test

You receive a clear report with photographs documenting the corrosion behavior: time to first rust, the percentage of affected surface, and the degree of blistering or coating loss. These insights help engineers and quality teams select the best coating systems, compare suppliers, and demonstrate compliance with corrosion resistance requirements, supporting confident decisions on product lifetime, reliability, and customer satisfaction.
 

Frequently Asked Questions

We review every request within 2 business days and get back to you with next steps. The test itself depends on the specific method and your requirements, our priority is always getting you an accurate result, not the fastest possible one.

In many cases, yes. If a specific standard, customer specification or internal protocol applies to your product, tell us and we'll assess whether we can test to it, either as a standard method or a custom one.

Some of our equipment is mobile, and part of our diagnostic work happens on your site. For large assemblies we also have large-format test capacity. Contact us with the dimensions and we look at the options.

Request this test

Send us your request with as much detail as you can share: material, component, quantity of samples,the standard you need to work to… We’ll review it and come back with scope, lead time and price. Drawings, specifications or earlier test reports help us assess feasibility faster.
