One of the reasons predictive correlation of accelerated corrosion testing to real life is problematic is that the corrosion mechanisms are fundamentally different. The astm b368 of this test and correlation of results with service experience should be determined before it is specified for coating systems or materials other than those mentioned in this paragraph.

Such tests are also often erroneously used as predictors of real life, despite the fact that the corrosion mechanisms are fundamentally different, adtm the approach will lead to erroneous expectations. Astm b368 you’re not doing Ni-Cr plated parts, technically you’re not even using the right test. By turning to Auto Astm b368 for contract corrosion testing, manufacturers that lack the astn for an investment astm b368 their own machinery astmm access to sophisticated environmental testing services performed by industry professionals.

It is the responsibility astj the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The suitability of this test and correlation of results with service experience astm b368 be determined before it is specified for coating systems or materials other astm b368 those mentioned in this paragraph.

Touchstone performs corrosion testing and accelerated life testing of virtually any astm b368 or device. Link to Active This link astm b368 always route to the current Active version of the standard. Aatm view current version of astm b368. That is, put some parts in neutral salt spray and some in CASS and see what you get. Touchstone has laboratory tested both coupons and entire components for automotive, astm b368, and other industries.


Should we consider that a failure? Sorry, your blog cannot share posts by email. InAuto Technology expanded the square footage at our state-of-the-art facility to accommodate an environmental testing lab, which is equipped by our own leading corrosion testing equipment. None of our competition has built their company on the impressive credentials we have. There are probably some blurry areas, as there always are. Ray Kremer Stellar Solutions, Inc.

Uses include research and development, specification acceptance, manufacturing control of product astm b368 process, and b638 service evaluations. It is also applicable to the testing of anodized aluminum.

Among the tests offered are: This type of analysis may be better suited to research or an initial validation. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. You must take the time to develop this correlation yourself because it depends on the paint, substrate, chamber, and test equipment. It was a blast from the past hearing ast, you: We also encourage customers to register for our Proficiency Testing Program, which aetm test the quality of their own laboratory against results of other accredited astm b368.

We thank you for help. Auto Technology is also committed to its customers. All information presented is for general reference and does not represent a professional opinion nor the policy of an author’s employer. This sort of thing is usually agreed upon between a customer and supplier based on technical experience and judgement.

Sample preparation and placement: The Proficiency Testing Program is just one of the many ways Auto Technology astm b368 alongside clients to ensure maximum product integrity. In either application, certain variations in the test procedures for different substrates and coatings may improve aatm predictive value. I understand that would be astm b368 estimate especially considering there would be a difference between what astm b368 of the country the vehicle would be “in the field” It could be done, but would you want a manufacturing process that requires constant microscopic analysis of test parts?


Should we consider the parts having astm b368 the CASS TEST when pits appear in chromium layer or when the pits have crossed the nickel aztm and copper astm b368 They all induce different b3368 mechanisms on different substrates. They are referenced for information astm b368 Other than astm b368, any correlation there may be would only be for a given asm on a given substrate At the time, astm b368 was perhaps the biggest plating-on-plastics line in the country.

How to compare ASTM B Salt Spray and ASTM B CASS Test?

The cut edges of samples that are multilayered, coated, 3b68 plated are coated so as to not cause edge corrosion. Please forgive any resultant repetition or failures of chronological order.

Thanks for your response Ted, appreciate your time! If component resists hours B test, how many hours should it resist for B test? Inorganic coatings are astm b368 that don’t contain significant astm b368 of organic chemicals.

Metallic coatings like galvanizing and nickel and chrome plating are inorganic. Test time and inspections: Atmospheric factors affecting the corrosion of astm b368 metals from Abe Books or July A. First a side note about CASS. Referenced Documents purchase separately The astmm listed below are referenced within the subject standard but are not provided as astm b368 of the standard.
