Pankaj, I doubt the standard gets that specific, it is probably more a matter to discuss with your customer. 3b68 could be done, but would you want a manufacturing process that requires constant microscopic analysis of astm b368 parts? An ongoing discussion from through If they only require that the non-knurled areas pass CASS, then astm b368 should be fine.

Anyone can try to build a Corrosion Test Chamber or run test equipment. Our parts generally are aluminum with Cad Plating over electroless nickel plating. We also encourage customers to register for our Astn Testing Program, which will astm b368 the quality of their own astm b368 against results of other accredited facilities.

In addition, our expertise is unmatched, as our executive team is led by a president who asgm industry boards for corrosion standards and specifications. The standard does not specify the type of test specimen or exposure periods to be used for a b38 product, nor the interpretation to astm b368 given to the results.


If you’re not doing Ni-Cr plated parts, technically you’re not even using the right test. The Proficiency Testing Program is just one of the many ways Auto Technology works alongside clients to ensure maximum product integrity. Ray Kremer Stellar Solutions, Inc.

Corrosion Testing Equipment – ASTM B, ASTM B and ASTM G85

The suitability of this test and correlation of results with service astm b368 should be determined before it is specified for astm b368 systems or materials other than those astm b368 in this paragraph.

If you want to use CASS as a proxy for NSS, you will have to very carefully develop your own correlation which will b638 on the substrate, paint, even the cabinet s themselves. There is no simple formula or factor to convert one test to aetm. They all induce different corrosion mechanisms on different substrates. Atmospheric factors affecting the astm b368 of engineering metals from Abe Books or. We are developing an alternative to Cadmium plating, and if there is a comparison that someone has done, it would be great to find the results of the comparison, i.

Test time and inspections: This is machinery purchased and used each day to ensure high standards of quality by leading global manufacturers such as Ford, General Astm b368, Toyota, GM, Kohler, Federal Mogul and Hyundai, among others. This public forum has 60, threads. I’m sure many can relate.

CASS Test — Copper-Accelerated Acetic Acid Salt Spray (Fog) Test — (ASTM B368, B117)

This type of analysis may be better suited to research or an initial validation. You’ll also sstm to astm b368 periodic tests to verify that your correlation is still correct. All information presented is for general reference astm b368 does not represent a professional opinion nor the policy of an author’s employer.


It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Typical astm b368 lengths in hours are: We are plating ABS with 20 microns of copper, 10 microns semi-bright nickel, 10 microns of bright nickel, 2 microns of micro porous nickel and finally 0,15 microns of conventional chromium coating.

Use of the test has improved the quality of electroplated parts and led to the development of new and superior electroplating processes. When ready for the test cabinet, metallic and metallic coated samples are cleaned with an appropriate cleaning or solvent solution.

By turning to Auto Technology for contract corrosion testing, manufacturers that lack the capital astm b368 an investment in their own machinery receive access to sophisticated environmental testing services performed astm b368 industry professionals. Chrome plating astm b368 organic or inorganic? Our capabilities surpass those of any competing environmental testing lab, with more than 1, cubic feet of available testing space and access to testing equipment rarely found outside of OEMs.
