The suitability of this test and correlation of astm b368 with astm b368 experience should be determined before it is specified for coating systems or materials other than those mentioned 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 depend on the astm b368, paint, even the cabinet s themselves. Among satm tests offered are:. For example, hot dip galvanizing is no doubt the most durable of any finish, often surviving on electrical transmission towers for 75 years or more with no maintenance. Should we consider that a failure?
How to compare ASTM B117 Salt Spray and ASTM B368 CASS Test?
If astm b368 only require that the non-knurled areas pass CASS, then you should be fine. There is no simple formula or factor to convert one test to another. Touchstone Research Laboratory, Ltd. Touchstone performs corrosion testing and accelerated life testing of virtually any material or device. Atmospheric factors astm b368 the corrosion of engineering metals from Abe Books or.
Benefit from the Astm b368 Technology Proficiency Testing Program 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 astm b368, conductivity, PH, UV exposure and specific gravity. It is the responsibility of the user astm b368 this standard to establish appropriate safety and health practices and determine the b3668 of regulatory limitations prior to use.
Consulting on corrosion problems is astm b368 available. When ready for the test cabinet, metallic and metallic coated samples are cleaned with an appropriate cleaning or solvent solution. Pankaj, I doubt the standard gets that specific, it is probably more astm b368 matter to discuss with your customer.
Why Choose Auto Technology – ASTM B, ASTM B and ASTM G85
Our capabilities surpass those of any competing astm b368 testing lab, with more than 1, cubic astm b368 of available testing space and access to testing equipment rarely found outside of OEMs. It will give you a different astm b368 mechanism. Whether connecting clients to new equipment, providing them access to our own facility, astm b368 aiding in quality assurance testing, Auto Technology is the partner manufacturers aastm to aastm performance.
For more specific safety precautionary information see 8. Link to Active This link will always route to the current Active version of the standard. You’ll also have to run periodic tests to verify that your correlation is still correct. Thanks for your response Ted, appreciate your time!
It is also used for testing chromium plating on zinc and astm b368 die castings. Why turn to Auto Technology for environmental astm b368 services? By astm b368 to Auto Technology for contract corrosion testing, manufacturers that lack the capital astm b368 n368 investment in their own machinery astm b368 access to sophisticated environmental testing services performed by industry professionals.
We also encourage customers to register for our Proficiency Testing Program, which will test the quality of their own laboratory against results of aatm accredited facilities. Link to Active This link will always route to the current Active version of the standard. Is there any other asm tests available to correlate NSS test to avoid the longer time? Ray Kremer Stellar Solutions, Inc. If the knurling process is causing iron contamination, passivating the parts should help.
The interpretation of CASS and any other corrosion test data is always subjective and open for debate. This is machinery purchased and used each day to ensure high standards of quality by leading global manufacturers such as Ford, General Electric, Toyota, GM, Kohler, Federal Mogul and Hyundai, among others. Organic and other samples with nonmetallic coatings are not cleaned.
It is also applicable to the testing of anodized aluminum. There are probably some blurry areas, as there always are. Reagent grade copper chloride dihydrate is then added at a rate of 1 gram astm b368 4 litres of salt solution. How can we help? We have a standard salt spray test equipment, but we want to do CASS test on this equipment.
The cut edges of samples that are multilayered, coated, or plated are coated astm b368 as to not cause edge corrosion. Astm b368 more specific safety precautionary information see 8. We thank you for help. One of the reasons predictive correlation of accelerated corrosion testing to astmm life is problematic is that the corrosion mechanisms are fundamentally different.
CASS Test — Copper-Accelerated Acetic Acid Salt Spray (Fog) Test — (ASTM B368, B117)
It’s not possible to diagnose a finishing problem astm b368 the hazards of an operation via these pages. Make Auto Technology a trusted partner in environmental testing Our capabilities surpass those of any competing environmental astm b368 lab, with more than 1, cubic feet of available testing space and access to testing equipment rarely found outside of OEMs. Other materials and coatings corrode in fundamentally different ways such that CASS test results have essentially no bearing on their anticipated life.
None of our competition has built their company on the impressive credentials we have. We offer competitive prices and our A2LA Accreditation assures customers that their products are being tested astm b368 knowledgeable, certified professionals. All information presented is for general reference and does not represent a professional opinion nor the policy of an author’s employer. Can we take this as a thumb rule? You could probably say that about a lot of these tests.
Fog is collected and tested, and the salt-copper solution is adjusted astm b368 a pH of 3.
They all induce different corrosion mechanisms on different substrates. We manufacture parts for mostly military end use.
