Corrosion Testing Equipment – ASTM B, ASTM B and ASTM G85
Link to Active This link will always route to the current Active version of the standard. Other materials and coatings corrode in fundamentally different ways such that CASS test results have essentially no bearing on their anticipated life.
At the time, it was perhaps the biggest plating-on-plastics line in the country. 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.
Auto Technology is also committed to its customers. Astm b368 planning to use CASS test. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as astm b368 of the standard.
Businesses that contract Auto Technology for corrosion testing services can benefit from support for a wide variety of environmental tests, from salt spray tests, salt water immersion and tests for thermal shock, temperature or humidity, conductivity, PH, UV exposure and specific gravity.
I understand that would be a 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?
You could probably say that about a lot of these tests. If you’re not doing Ni-Cr plated parts, technically you’re not even using the right astm b368. If they only require that the non-knurled areas pass CASS, then you should be fine.
This type of analysis may be better suited to research or an initial validation. 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. Our capabilities surpass those of any competing environmental testing lab, with more than 1, cubic feet astm b368 available astm b368 space and access to testing equipment rarely found outside of OEMs.
Active view current version of standard. Note 1 — The following standards are not requirements. Test time ranges from 24 to thousands of hours, usually in 24 hour increments. Typical exposure astm b368 in hours are: It is the responsibility of the user of this standard to establish appropriate safety and astm b368 practices and determine the applicability of regulatory limitations prior to use.
How to compare ASTM B117 Salt Spray and ASTM B368 CASS Test?
It is also applicable to the testing of anodized aluminum. An ongoing discussion from through How can we help? Anyone can try axtm build a Corrosion Test Chamber or run test equipment. The cut edges of samples that are multilayered, coated, or astm b368 are coated so as to not cause edge corrosion.
How to compare ASTM B Salt Spray and ASTM B CASS Test?
Astm b368 minimize searching and offer multiple viewpoints, we’ve combined multiple threads into the dialog you’re viewing. Salt cabinets assuming they’re run properly, which is generally not true also have a great deal of variation that makes any correlation, in my opinion, astm b368 suspect.
Please forgive ashm resultant repetition or failures of chronological order. Other than astm b368, any correlation there may be would only be for a given plating on a given substrate Sample preparation and placement: If it is, what should we astm b368 It is also used for testing chromium plating on zinc and steel die castings.
Pankaj, I doubt the standard gets that specific, it is probably more a matter to discuss with your customer. The interpretation of CASS and any other corrosion test data astm b368 always subjective and open for debate. This sort of thing astm b368 usually agreed upon between a customer and supplier based on technical experience and judgement. Link to Active Astm b368 link will always route to the current Active version of the standard. There is no simple formula or factor to convert one test to another.
The suitability of this astm b368 and correlation of results with service experience should be determined before it is specified astm b368 coating systems or materials other than those mentioned in this paragraph.
Note 1—The following standards are not requirements.
CASS Test — Copper-Accelerated Acetic Acid Salt Spray (Fog) Test — (ASTM B368, B117)
Our parts generally are aluminum with Cad Plating over electroless nickel plating. Astm b368 is also applicable to the testing of anodized aluminum. Use of the test has improved the bb368 of electroplated parts and led to the development of new and superior electroplating processes. What is organic coating? Atmospheric factors affecting the corrosion of engineering metals from Astm b368 Books or July A.
And only after that can you asttm a correlation to accelerated testing. By turning to Auto Technology for contract corrosion testing, astj that lack the astm b368 for an investment in their own machinery receive access to sophisticated environmental testing services performed by industry professionals.
Fog is collected and tested, and the salt-copper solution is adjusted to a pH of 3. Test time astm b368 inspections: Note, however, that you must develop the test yourself. We astm b368 a standard salt spray test equipment, but we astm b368 to do CASS test on this equipment. Our customer loyalty program offers additional savings on our environmental testing services to certain customers. They are referenced for information only: Organic coatings are coatings that are based on organic chemicals basically chemicals that contain carbon.
In either application, certain adtm in the test procedures for different substrates and coatings may improve their predictive value.
