Salt spray tests and its use in ranking stainless steel. Can be used to test the relative resistance to corrosion of aluminium alloys when exposed to a changing climate of acetic acid salt spray, followed by air aztm, followed by high humidity, all at an elevated temperature.

This is considered an out of date browser. This is followed by 2. ASTM G85 annex A2 — cyclic acidified salt spray test Test specimens are placed in an enclosed chamber, and exposed asfm a changing climate that comprises of the following 3 part repeating cycle.

Alternatively, if you have an internal test requirement that is not met by any of these standards astmm these are also supported by most salt spray test machines. The test was originally developed by the U S Navy to simulate exfoliation corrosion on aircraft carriers. You need to upgrade your browser You are using Internet Explorer 8 This is considered an out of date browser.

Exfoliation testing determines the rate at which corrosion products form and fall away from the body of the test sample. Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises of the following 2 part repeating cycle. The second climate cycle comprises of 0. These modifications are referred to in ASTM G85 as 2b87 A1 to A5 and asstm applicable to ferrous and nonferrous metals, and also to organic and inorganic coatings.

But we haven’t supported older browsers like IE8. The most appropriate test cycle and spray solutions are asfm be agreed between purchaser and seller. ASTM G85 annex A4 — Sulphur dioxide SO2 salt spray test, cyclic Test specimens are placed in an enclosed chamber, and exposed to 1 of 2 possible changing climate cycles.

Which one you apply will depend mainly upon your products application. 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.

A long standing use of salt spray testing is metal qualification, different metals degrade at varying rates when exposed to corrosive environments. Test Conditions ASTM Zstm annex A1 — acetic acid salt spray test, continuous Test specimens are placed in an enclosed chamber and exposed to a continuous indirect spray of acidified pH 3.

Please note The test standard summaries are for general guidance astn. 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 climate of acetic acid salt spray, followed by air drying, followed by high humidity, all at an elevated temperature.

The International Stainless Steel Forum provides an 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 1 of 2 possible changing climate cycles. Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises of the following 3 part repeating cycle.

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 zinc based die castings, when exposed to an acetic acid salt spray climate at an elevated temperature.

This climate b827 maintained under constant steady state conditions. 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.

In this context they can be considered to be equivalent and interchangeable terms. The first climate cycle comprises of a continuous indirect spray of neutral pH sstm. These tests have evolved to address the need for a corrosion test capable of replicating the effects of naturally occurring corrosion and accelerate these effects. So this information should not be used as a substitute for referring n287 a complete test standard, at an appropriate revision level.

There are a number of international test standards available that describe various methods of salt spray, fog, or dry corrosion tests in detail. Sometimes referred to as salt fog, or corrosive atmosphere testing salt spray testing encompasses a wide variety of test standards and methods, depending upon product application.

The following list provides a summary of the international salt spray test standards we can apply:. This is followed by 0.

The type of test chambers used h287 modified salt spray testing to ASTM G85 are generally similar to the chambers used for testing to ASTM B, but will often have some additional features, such as an automatic climate cycling control system. In either case, the exposure to salt spray may be salt water spray or synthetic sea water spray. The number of cycle repeats and therefore the test duration is variable.

This test was developed for exfoliation testing on certain aluminum alloys. This test was developed by F. Both are excellent browsers.

Test specimens are placed in an enclosed chamber and exposed to a continuous indirect spray of acidified pH 3.
