There are a number of international test standards available that describe various methods of salt spray, fog, or dry corrosion tests in detail. Exfoliation testing determines the rate at which corrosion products form and fall away from the body of the test sample.

ASTM G85 annex A2 — cyclic acidified salt spray test Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises of the following 3 part repeating cycle. But we haven’t supported older browsers like IE8. Website asmt by Peter Bourne Communications. Contact Ascott for Further Information.

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.

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.

Though believed to be accurate at the time of writing, this may change over time. You need to upgrade your browser You are using Internet Explorer 8 This is considered an out of date browser. 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: This is followed by 1.

The number of cycle repeats and therefore the test duration is variable.

This test was originally published as ASTM G43, and is used to determine corrosion resistance in a severe marine atmosphere. 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.

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.

The following list provides a summary of the international salt spray test standards we asfm apply:.

B278 test was developed for exfoliation testing on certain aluminum alloys. Test specimens are placed in an enclosed chamber and exposed to a continuous indirect spray of acidified pH 3.

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. 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.

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. This is considered an out of date browser.

ASTM G85 annex A2 – cyclic acidified asym 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.

Satm spray testing is conducted to determine the products resistance to corrosion, it is often conducted at b2887 product level to provide quick feedback to the development team on coatings, enclosures and connectors.

Both are excellent browsers. 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. Test specimens are placed in an enclosed chamber, and exposed to 1 of 2 possible changing climate cycles.

The test was originally developed by the U S Navy to simulate exfoliation corrosion on aircraft carriers. This climate is maintained under constant steady state conditions.

The test duration is variable. This test was developed by F. A long standing use of salt spray testing is metal qualification, different metals degrade at varying rates when exposed to corrosive environments. This is followed by 3. 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 changing climate that comprises of the following 2 part repeating cycle.

ASTM B – 74 Method of Acetic Acid-Salt Spray (Fog) Testing (Withdrawn )

Please note The test standard summaries are for general guidance only. The first climate cycle comprises of a continuous indirect spray of neutral pH 6. So this information should not be used as a substitute for referring to a complete test standard, at an appropriate revision level. This website has been developed with modern browsers in mind to allow it to display at its best in a wide variety of viewing situations – including mobile viewing.

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. The second climate cycle comprises of 0. This is followed by 0.

Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises of the following 3 part repeating cycle. Salt spray tests and its use in ranking stainless steel. 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. In this context they can be considered to be equivalent and interchangeable wstm.

The most appropriate test cycle and spray solutions are to be agreed between purchaser and seller. These modifications are referred to in ASTM G85 as annexes A1 to A5 and are applicable to ferrous and nonferrous metals, asstm also to organic and inorganic coatings.

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.
