SALT SPRAY TESTING

PUT YOUR FINISH TO THE TEST

Corrosion failures cost more than just parts. They damage timelines, reputations, and bottom lines. That’s why Lewis Engineering uses salt spray testing to verify that painted or plated parts meet corrosion resistance standards before they ever leave the building. Whether you’re working to military specs, industrial standards, or internal quality benchmarks, we can confirm that your coatings will hold up over time.

This is the same test we use on our own parts. If we plated it, painted it, or assembled it, we can prove it performs.

Salt spray testing is ideal for:

Painted or plated parts requiring rust-resistance verification
Meeting military and industrial corrosion standards
Supporting chromate, phosphate, and passivated coatings
In-house validation before delivery or final inspection

No guesswork. No assumptions. Just proven performance you can document.

BUILT TO VERIFY

We operate an in-house salt spray tank to run standardized corrosion tests in accordance with ASTM B117 and ISO 9227. It’s part of our larger quality control system and helps us confirm that surface treatments meet the durability requirements of your application, especially for defense, aerospace, and industrial use.

Every tested part comes with documentation and peace of mind.

WHY LEWIS FOR SALT SPRAY TESTING?

Fully integrated into our quality control process

You need proof that your parts will perform, and you shouldn’t have to wait for it. Our in-house salt spray testing gives you fast, reliable results that meet your specs and keep production moving.

Salt Spray Testing FAQs

Get answers to common questions about Lewis Engineering’s in-house salt spray testing, standards, results, and quoting.

What is salt spray testing used for?

This testing method is used to verify how well painted or plated parts resist corrosion. Testing is typically conducted to confirm that a coating will provide the required performance prior to shipment or final inspection.

Does salt spray testing help evaluate corrosion resistance?

Yes. At Lewis Engineering we utilize an in-house salt spray testing tank to evaluate corrosion resistance and confirm that surface treatments meet the durability requirements of the application.

What types of coatings or finishes can be evaluated with salt spray testing?

Painted and plated components can be evaluated including chromate, phosphate and passivated coatings. Testing helps verify that your finish is providing the needed corrosion protection.

Can salt spray testing be combined with zinc phosphate or metal painting services?

Salt spray testing can easily be integrated with Lewis Engineering’s finishing services to verify coating performance before parts leave the facility. It can also be provided as a standalone service.

What industries use salt spray testing?

Defense, aerospace and heavy industrial applications typically rely on this type of testing where corrosion resistance and coating performance are important. We can test to military, industrial or internal quality requirements.

What information should I provide when requesting salt spray testing?

Provide as much details about the part, coating or finish being evaluated and any applicable corrosion-resistance or testing requirements. If your project must meet a specific standard, such as ASTM B117 or ISO 9227, include that information so our team can evaluate your testing needs.
