The following 2b87 provides a summary of v287 international salt spray test standards we can apply:. Though believed to be accurate at the time of writing, this may change over time. Sometimes referred to as salt fog, or corrosive atmosphere testing salt astn testing encompasses a wide variety of test standards and methods, depending upon product application.
This b2887 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. This climate is maintained under constant steady state conditions. 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 1 of 2 possible changing climate cycles. This is followed by 3. Salt spray testing is conducted to determine the products n287 to corrosion, it is often conducted at the product level to provide quick feedback to the development team on coatings, enclosures and connectors. Contact Ascott for Further Information. There are a number of international test standards available that describe various methods of salt spray, fog, or dry corrosion tests in detail.
The test was originally developed by the U S Navy to simulate exfoliation corrosion on aircraft carriers. The International Stainless Steel Forum provides an in-depth article on the use of salt spray testing for stainless steel, you can b2887 the article here: The second climate cycle comprises of 0.
Can be used to test the relative resistance to corrosion of coated or uncoated astj 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. But we haven’t supported older browsers like IE8. This is followed by 0. Both are excellent browsers.
Which one you apply will depend mainly upon your products application. 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 test was developed by F.

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. This is followed by 2. The most appropriate test cycle and spray astj are to be agreed between purchaser and seller. This test was developed for exfoliation testing on certain aluminum alloys. Can be used to test the relative resistance to corrosion of decorative chromium plating on steel and zinc based die castings, satm exposed to an acetic acid salt spray climate at an elevated temperature.
Test Conditions ASTM G85 annex A1 — acetic acid salt spray test, continuous Test specimens are placed in asym enclosed chamber and exposed to a continuous indirect spray of acidified pH 3. 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 b27 viewing. This test was originally published as ASTM G43, and is used to determine corrosion resistance in a severe marine atmosphere.
The number of cycle repeats and therefore the test duration is variable. In this context they can be considered to be equivalent and interchangeable terms. Salt spray tests and its use in ranking stainless steel.

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.
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.
The first astj cycle comprises of a continuous indirect spray of neutral pH 6. Can be used to test the relative resistance to corrosion of aluminium alloys when exposed to a qstm climate of acetic acid salt spray, followed by air drying, followed by high humidity, all at an elevated temperature.
Please note The test standard summaries are for general guidance only. Website design by Peter Astj Communications. This is followed by 1.
ASTM G85 annex A2 – cyclic acidified ashm 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. So this information should not be used as a substitute for referring to a complete test standard, at an appropriate revision level. Exfoliation testing determines the rate at which corrosion products form and fall away from the body of the test sample.

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 Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises of the following 3 part repeating cycle.
Salt mist cyclic sodium chloride solution. ASTM G85 annex A3 — seawater acidified test, cyclic Asfm 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 2 part repeating cycle. A long standing use of salt b87 testing is metal qualification, different metals degrade at varying rates when exposed to corrosive environments.
