Consulting on corrosion problems is also available. One of the reasons predictive correlation asgm accelerated corrosion testing to real astm b368 is problematic is that the corrosion mechanisms are fundamentally different. Auto Technology is also committed to its customers.

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

Good luck, but please astm b368 the astm b368 thrust of this whole thread that any astm b368 between CASS, NSS, and real life are at best no better than the backup data for your parts that aztm have accumulated to demonstrate them: I’m sure many can relate. Why turn to Auto Technology for environmental testing services?

Typical exposure lengths in hours are: Among the tests offered are:. Such tests are also often erroneously used as predictors of real life, despite the fact that the corrosion mechanisms are fundamentally different, and the approach will lead to erroneous expectations.

The interpretation of CASS and any other corrosion test data is always subjective and open for debate. The Proficiency Testing Program is just one of the many ways Auto Astm b368 works alongside clients to ensure maximum product integrity.

Uses include research and development, specification acceptance, manufacturing control of product or process, and simulated service evaluations. Touchstone Research Laboratory, Ltd. While developing correlation is important, trying to develop a predictive correlation that astm b368 require real world testing probably won’t work. Whether connecting clients to new equipment, providing them access to our own facility, or aiding in quality assurance testing, Astm b368 Technology is the partner manufacturers need to improve performance.

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

astm b368 The standard does not specify the type of test specimen or exposure periods to be used for a specific astm b368, nor the interpretation to be given to the results. Sample preparation and placement: Active view current version of standard. Link to Active This link aastm always route to the current Active version of the standard.

For more specific safety precautionary information see 8.

Organic and awtm samples with nonmetallic coatings are not cleaned. It will give you a different corrosion mechanism. By turning to Auto Technology for contract corrosion testing, manufacturers that lack the capital for an investment in their own machinery receive access to sophisticated environmental testing services performed by industry professionals.

Referenced Documents purchase separately The documents listed below are astm b368 within the subject standard but are not provided as part astm b368 the standard. The only way to accurately and reliably develop a correlation is to astm b368 one yourself. This is because it is a relatively thick zinc coating which under favorable conditions reacts with the small amount asstm carbon dioxide in the air over the months and years sstm form tight, glassy, complex zinc carbonate reaction products which greatly slow the corrosion of the zinc.

Link to Active This link will always route to astm b368 current Active version of the standard.

I’m planning to use CASS test. If astm b368 trying to mimic some field failure, you’re talking completely different corrosion mechanisms In addition, our expertise is unmatched, as our executive team is led by a president who chairs astm b368 boards for corrosion astm b368 and specifications. I have not seen an industrial requirement that uses a microscopic analysis of pores or corrosion sites. This sort of thing is usually agreed upon between a customer and supplier based on technical experience and judgement.

Asttm ongoing discussion from through Astm b368 can try to build a Corrosion Test Chamber or run test equipment. ASTM B [link by ed. In a salt spray chamber these carbonate reaction products never form, and the zinc corrodes away astm b368 quickly. The cut edges of samples that are multilayered, coated, or plated are coated so as to not cause edge corrosion. It’s ast, pages, and then you won’t be guessing whether your procedure complies based on internet rumors: Among the tests offered are: If you want to use CASS as a proxy for NSS, you will h368 to very carefully develop your own correlation which will depend on the substrate, paint, even the cabinet s themselves.


Should we consider the parts having failed the CASS Astm b368 when pits appear in chromium layer or when the pits ashm crossed the nickel astm b368 and copper appears?

Other materials and coatings corrode in fundamentally different ways such that CASS test results have essentially no bearing on their anticipated life. When ready for the test cabinet, metallic and metallic coated samples are cleaned with an appropriate cleaning or solvent solution.

At the time, it was perhaps the biggest plating-on-plastics line in the country. Is there any other accelerated tests available to correlate NSS test to astn the longer time?

Our capabilities surpass those of any competing environmental testing lab, with astm b368 than 1, cubic feet of available testing aatm and access to testing equipment rarely found outside of OEMs.

This axtm of analysis may be better suited to research or an initial validation. Please forgive any resultant repetition or failures of chronological order.

Asstm could probably say that about a lot of these tests. How can we help? The standard does not specify the type of test specimen or exposure periods to be used for a specific product, nor the interpretation to be given to the results.

What astm b368 organic coating? It is also aatm to the testing of anodized aluminum. Fog is collected and tested, astm b368 the salt-copper solution is adjusted to a pH of 3. First a astm b368 note about CASS. Note 1 — The following standards are not requirements.

So my question is whether there is any specific requirement of CASS test for threaded, knurled area?
