There are three distinct test method in ISO the neutral salt spray (NSS), the acetic acid salt spray (AASS), and copper-accelerated acetic. ISO NSS. adv. auto technology banner. A discussion started in but continuing through Q. We have a customer, that we supply some zinc. The salt spray (or salt fog) test is a standardized and popular corrosion test method, used to Other important relevant standards are ISO, JIS Z and ASTM G The most common test for steel based materials is the Neutral Salt Spray test (often abbreviated to NSS) which reflects the fact that this type of test.

We have a customer, that we supply some zinc electroplated mechanical components to.

Is there any equivalence between this two standards? Hi Sergio, ASTM B does not address corrosion behavior of test specimens, but describes the parameters for conducting a salt spray test. So if you want to know how to set up a salt spray cabinet or how to make the salt solution, then B is a reference. But benchmarking performance is something altogether different.

Salt spray test – Wikipedia

I suggest that you send some parts out for testing according to the ISO standard to see if they meet the spec. Nsz the only way to know for sure. Options include the following:.


Something totally different like zinc-alloy plating, organic coatings, etc.

A personal good afternoon to all, I am Jose of Curitiba, I am a painting inspector, I am a specialist in the area of Salt Spray, and have a problem and knowing of the competence of all readers in corrosion, perhaps they can help me. I am needing to know if a gradual table of corrosion in assay exists of Salt Spray, if this table exists and if anyone would be able to post it, I will be thankful. Is it possible to reduce test duration by some accelerated Testing?

Equivalence between ASTM B-117 vs. ISO 9227 NSS

Any ISO standard is available for this Testing? But which, is any, accelerated test is appropriate depends on what the finish is, and what you hope to test against. Remember that accelerated testing is not a proper indication of real world performance.

We did tests of our products under ISO Hi David, There are several differences between the two specifications, including salt concentration range, salt analysis, water quality, angle of inclination of test panels, corrosivity requirements, I think the temperature is about the only thing that has been standardised.

You will then isk to talk to your customer about the possibility of using one specification in lieu of the other. Dear Brian and Davey, Thank you very much for your answers. So I will start with benchmark with these two standards.


What is major difference between ISO [link by ed. Brian Terry has directly answered your question, but please post your situation rather than an abstract question so that readers can best help you. What do you want to test? A requirement that a component ‘pass’ an accelerated corrosion test isn’t often meaningful until the finishing spec tells you what that means: It’s not possible to diagnose a finishing problem or the hazards of an operation via these pages.
