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.

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. 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. The first climate cycle comprises of a continuous indirect spray of neutral pH 6. The test duration is variable.

The most appropriate test cycle and spray solutions are to be agreed between purchaser and seller. ASTM G85 annex A4 — Sulphur dioxide SO2 salt spray bb287, cyclic Test specimens are placed in an enclosed chamber, and exposed to 1 of 2 possible changing climate cycles.

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 3. The second climate cycle comprises aetm 0. But we haven’t supported older browsers like IE8.

Both are excellent browsers. Test specimens asrm placed in an enclosed chamber, and exposed to a changing climate that comprises of the following 3 part repeating cycle.

This climate is maintained under constant steady state conditions. In this context they can be considered to be equivalent and interchangeable terms. This test was developed for exfoliation testing on certain aluminum alloys.

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.

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.

Though believed to be accurate at the time of writing, this may change over time. Salt mist cyclic sodium chloride solution. 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 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 number of cycle repeats and therefore the test duration is variable.

Contact Ascott for Further Information. 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.

This test was developed by F. The following list provides a summary of the international salt spray test standards we can apply:.

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

Website design by H287 Bourne Communications. Which one you apply will depend mainly upon your products application. 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. A long standing use of salt spray testing is metal qualification, different metals degrade at varying rates when exposed to corrosive environments.

Salt spray tests and its use in ranking stainless steel. 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. 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.

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.
