Why this test matters
Moisture that collects on a surface overnight, or in an enclosed or humid space, can be just as damaging as rain: it leads to corrosion, blistering, or coating delamination over time. The condensation test simulates exactly that kind of long-term surface wetting, exposing your material or coating to an atmosphere held at 100% relative humidity so condensation forms continuously on the surface, the same way dew does. This matters for metals, plastics, composites, and coatings that need to hold up in humid or condensation-prone environments, and it's often run alongside a salt spray test for a fuller picture of corrosion resistance.
How the test works
Your sample, up to 20 kg, is placed in a test cabinet held at elevated temperature and humidity, with any cut edges coated beforehand so they don't skew the result. The sample stays in the cabinet for a set period, anywhere from 1 hour up to 10,000 hours depending on your standard or requirement, while we check how the corrosion evolves at regular intervals throughout. We can test coated or uncoated material, and undamaged or deliberately scratched samples, whichever gives you the most relevant picture of how your product will actually perform.
What you learn from this test
You receive a clear report with photographs documenting exactly how corrosion developed over the course of the test: where it started, how it spread, and how your coating or material held up. This lets you compare protective coatings or surface treatments, confirm a coating performs as promised, and validate your product's durability before it faces real humid or condensation-prone conditions. Combined with a salt spray test, it gives you a complete, evidence-based picture of corrosion resistance.
