Contact Ascott for Further Information. 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.

ASTM G85 annex A2 — cyclic acidified salt aztm test Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises of the following 3 part repeating cycle.

In this context they can be considered to be equivalent and interchangeable terms. 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. The number of cycle repeats and therefore the test duration is variable.

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.

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

This is followed by 0. Salt spray tests and its use in ranking stainless steel.

This test was developed for exfoliation testing on certain aluminum alloys. This is followed by 3.

In either case, the exposure to salt spray may be salt water spray or synthetic sea water spray. This climate is maintained under constant steady state conditions.

Though believed to be accurate at the time of writing, this may change over time. Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises of the following 2 part repeating cycle. The test duration is variable. The second climate cycle comprises of 0. The first climate cycle comprises of a continuous indirect spray of neutral pH 6.

This test was developed by F.

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 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 axtm elevated temperature.

Can be used to asstm 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.

Test specimens are placed in an enclosed chamber, and exposed to 1 ashm 2 possible changing climate h287. A long standing use of salt spray testing is metal qualification, different metals degrade at varying rates when exposed to corrosive environments. 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.

These tests have evolved to address the need for a corrosion test capable of replicating the effects of asrm occurring corrosion and accelerate these effects. Both are excellent browsers. 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.

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. 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.

Salt mist cyclic sodium chloride solution. Test Conditions ASTM G85 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. So this information should not be used as a substitute for referring to a complete test standard, at an appropriate revision level. Please note The test standard summaries are for general guidance only. This is considered an out of date browser. Alternatively, if you have an internal test requirement that is not met by any of these standards than these are also supported by most salt spray test machines.

Test specimens are placed in an enclosed chamber and exposed to a continuous indirect spray of acidified pH 3. This test was originally published as ASTM G43, and is used to determine corrosion resistance in a severe marine atmosphere. 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. Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises of the following 3 part repeating cycle.

Which one you apply will depend mainly upon your products application. 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: The test was originally developed by the U S Navy to simulate exfoliation corrosion on aircraft carriers. The most appropriate test cycle and spray solutions are to be agreed between purchaser and seller.

Website design by Peter Bourne Communications. The type of test chambers used for 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.
