Salt Spray Testing
Accelerated salt spray corrosion testing to evaluate the durability, corrosion resistance and protective performance of metals, coatings and finished products under simulated aggressive environmental conditions.
Accelerated Corrosion Testing for Long-Term Performance
Salt Spray Testing is one of the most widely accepted accelerated corrosion testing methods used to determine the corrosion resistance of metallic materials, protective coatings and surface treatments.
At Om Metalab, we simulate highly corrosive salt fog environments to evaluate how materials perform under prolonged exposure to chloride-rich atmospheric conditions. This enables manufacturers to predict product durability before field deployment.
Our testing supports quality assurance, product development, coating validation and compliance with international corrosion testing standards.
Salt Spray Testing Methods We Offer
Our laboratory performs multiple internationally recognized salt spray corrosion tests depending on coating type, material and application requirements.
Neutral Salt Spray (NSS)
Standard accelerated corrosion test using a 5% sodium chloride solution to evaluate metal coatings, anodized surfaces and organic coatings under controlled laboratory conditions.
Acetate Salt Spray (ASS)
An acidic variation of the NSS test designed for decorative coatings such as copper-nickel-chrome systems and anodized aluminium components.
Copper Accelerated Salt Spray (CASS)
High-severity corrosion testing using copper chloride and acetic acid to evaluate multilayer decorative coatings and demanding corrosion-resistant finishes.
Alternating Salt Spray Test
Cyclic corrosion testing combining salt fog and humidity exposure to simulate real-world marine and industrial environments for coated components.
Why Salt Spray Testing Is Important
Salt spray testing helps manufacturers evaluate the corrosion resistance of materials and coatings before products are exposed to harsh outdoor, marine and industrial environments.
Early identification of coating failures and corrosion risks helps improve product reliability, reduce maintenance costs and extend service life.
- Protective Coating Evaluation
- Corrosion Resistance Verification
- Product Life Prediction
