Salt Spray Testing Laboratory
Accelerated corrosion-resistance testing to ASTM B117, performed in our NABL-accredited laboratory.
What Is Salt Spray Testing
Salt spray testing (also called salt fog testing) is an accelerated corrosion test used to evaluate the corrosion resistance of coated and uncoated metal samples. The sample is exposed to a controlled saline mist environment inside a sealed test chamber for a defined duration, after which the surface is examined for rust, pitting, or coating degradation.
Why Corrosion Testing Matters
- Verifies that protective coatings (galvanizing, powder coating, plating) meet corrosion-resistance specs.
- Ensures quality compliance for components specified to automotive, aerospace, or industrial standards.
- Identifies coating or material weaknesses before field failure, saving costly repairs or failures in service.

Frequently Asked Questions
How long does salt spray testing take?
The exposure duration depends on your product specifications; common test lengths range from 24 hours for basic screening to 480+ hours for marine/automotive coatings. Reports are delivered within 24 business hours of test completion.
What standards is salt spray testing performed to?
We test primarily to ASTM B117, ISO 9227, and IS 9000 standards. Let our team know if your project has custom specification requirements.
Do you provide a NABL-accredited certificate?
Yes, all salt spray test reports are issued under our NABL accreditation, ensuring the results are recognized and defensible for compliance and audit purposes.
