Exfoliation testing determines the rate at which corrosion products form and fall away from the body of the test sample. Typical Applications ASTM G85 annex A1 – acetic acid salt spray test, continuous Can be used to test the relative resistance to corrosion of decorative chromium plating on steel and asfm based die castings, when exposed to an acetic acid salt spray climate at an elevated temperature.

Salt spray tests and its use in ranking b28 steel. Test specimens are placed in an enclosed chamber, and exposed to 1 of 2 possible changing climate cycles. Website design by Peter Bourne V287.

These modifications are referred to in ASTM G85 as annexes A1 to A5 and are applicable to ferrous and nonferrous metals, and also to organic and inorganic coatings.

Salt Spray Testing :: Corrosion Testing Services

There are a number of international test standards available that describe various methods of salt spray, fog, or dry corrosion tests in detail. Salt spray testing is conducted to determine the products resistance to corrosion, it is often conducted at the product level to provide quick feedback to the development team on coatings, enclosures and connectors.

This is followed by 0. This is followed by 1. So this information should not be used as a substitute for referring to a complete test standard, at an appropriate revision level. Salt mist cyclic sodium chloride solution. A long standing use of salt spray testing is metal qualification, different metals degrade at varying rates when exposed to corrosive environments.

In this context they can be considered to be equivalent and interchangeable terms. This is considered an out of date browser. Contact Asrm for Further Information. ASTM G85 annex A3 — seawater acidified test, cyclic Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises of the following 2 part repeating cycle.

Can be used to test the relative resistance to corrosion of coated or uncoated aluminium alloys and other metals, when exposed to an changing climate of acidified synthetic seawater spray, followed by a high humidity, both at an elevated temperature. The number of cycle repeats and therefore the test duration is variable. Which one you apply will depend mainly upon your products application.

The International Stainless Steel Forum provides b27 in-depth article on the use of salt spray testing for stainless steel, you can find the article here: Test specimens are placed in an enclosed chamber, and exposed to ast, changing climate that comprises of the following 3 part repeating cycle.

This test was developed by F. Please note The test standard summaries are for general guidance only.

ast But we haven’t supported older browsers like IE8. Test specimens are placed in an enclosed chamber and exposed to a continuous indirect spray of acidified pH 3. This climate is maintained under constant steady state conditions.

The most appropriate test cycle and spray solutions are to be agreed between purchaser and v287. ASTM G85 annex A2 – cyclic acidified salt spray test Can be used to test the relative resistance to corrosion of aluminium alloys when exposed to a changing sstm of acetic acid salt spray, followed by air drying, followed by high humidity, all at an elevated temperature.

This acceleration arises through the use of chemically altered salt spray solutions, often combined with other test climates and in most cases, the relatively rapid cycling of these test climates over time.

This test was developed for exfoliation testing on certain aluminum alloys. ASTM G85 annex A3 – seawater acidified test, cyclic Can be used to test the relative resistance to corrosion of coated or uncoated aluminium alloys and other metals, when exposed to an changing climate of acidified synthetic seawater spray, followed by a high humidity, both at an elevated temperature.

Can be used to test b27 relative resistance to corrosion of aluminium alloys when exposed to a changing climate of acetic acid salt spray, followed by astmm drying, followed by high humidity, all at an elevated temperature.

The type of test chambers used for modified salt spray testing to ASTM G85 are generally similar to the chambers used for testing asrm ASTM B, but will often have some additional features, such as an automatic climate cycling control system. Can be used to test the relative resistance to corrosion of decorative chromium plating on steel and zinc based die castings, when exposed to an acetic acid salt spray climate at an elevated temperature.

These tests have evolved to address the need for a corrosion test b2887 of replicating the effects of naturally occurring corrosion and accelerate these effects. In either case, the exposure to salt spray may be salt water spray or synthetic sea water spray.
