Corrosion Testing
Opening a salt spray chamber
In the salt spray test (also salt spray chamber test, corrosion test), a NaCl solution generates a corrosion-promoting mist inside a test chamber. Under defined conditions (concentration, temperature, pH value, pressure), a reproducible environment is created that accelerates corrosion and allows assessment of corrosion resistance.
With testing according to DIN EN ISO 9227 (NSS), we evaluate metals, coated components, and assemblies. Typical test durations are 24 h, 96 h, 240 h, 480 h, 720 h or longer – depending on requirements and specifications.
After the test is completed, the samples are rinsed with deionized water, visually inspected, and the corrosion degree is recorded. You receive the digital test report by email.
Additional Procedures
Environmental simulation to evaluate corrosion resistance.
Zeros GmbH is an independent testing laboratory for destructive and non-destructive materials testing. We support companies from incoming inspection to series release – including digital test reports and full traceability.
We operate under accreditation to DIN EN ISO/IEC 17025 (quality management for laboratories). See our current accreditation information here.
We are accredited by DAkkS to DIN EN ISO/IEC 17025. This standard ensures that test methods, equipment control, personnel qualification and reporting meet the highest requirements.
An overview of services and scopes is available on our homepage.
Our portfolio covers NDT (UT, RT, MT, PT, VT), mechanical testing (tensile, hardness, Charpy), metallography (microstructure, grain size, coating thickness) and chemical analysis (e.g. OES, XRF). We also provide specimen preparation, documentation and consulting.

NaCl Mist According to DIN EN ISO 9227
In the salt spray chamber, a salt solution (NaCl) under compressed air generates a fine mist that evenly exposes the samples. The constant test conditions enable comparisons between materials, coatings, and batches.
The assessment is based on the test time until corrosion onset (e.g. red rust formation on steel) and a documented visual inspection.
