These tests have evolved to address the need for a corrosion test capable of replicating the effects of naturally occurring asm and accelerate these effects.

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 asmt zinc based die castings, when exposed to an acetic acid salt spray climate at an elevated temperature. The test duration is variable.

ASTM-B | Method of Acetic Acid-Salt Spray (Fog) Testing (Withdrawn ) | Document Center, Inc.

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

Which one you apply will depend mainly upon your products application. 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. Exfoliation testing determines the rate at which corrosion products form and fall away from the body of the test sample. In this context they can be considered to be equivalent and interchangeable terms.

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 most appropriate test cycle and spray solutions are to be agreed between purchaser and seller. 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 first climate cycle comprises of a continuous indirect spray of neutral pH 6. This is followed by 2. 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 A2 – cyclic acidified salt spray test Can be used to test the relative resistance to corrosion of aluminium alloys when exposed 2b87 a changing climate of acetic acid salt spray, followed by air drying, followed by high humidity, all at an elevated temperature.

A long standing use of salt spray testing is metal qualification, different metals degrade ast, varying rates when exposed to corrosive environments. This climate is maintained under constant steady state conditions. This is followed by 3.

Alternatively, b27 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.

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

The test was originally developed by the U S Navy to simulate exfoliation corrosion on aircraft carriers. Test specimens are placed in an enclosed chamber, and exposed to 1 of 2 possible changing climate cycles. Contact Ascott for Further Information. But we haven’t supported older browsers like IE8.

This test was developed for exfoliation testing on certain aluminum alloys. 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 a changing climate that comprises of the following 2 part repeating cycle.

Website design by Peter Bourne Communications. This test was developed by F. 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:. So this information should not be used as a substitute for referring to a complete test standard, at an appropriate revision level.
