Intelligent Digital Laboratory Corrosion Salt Spray Environmental Test Corrosion Chamber
ASTM B117 was the first internationally recognized salt spray standard, originally published in 1939. Other important relevant standards are ISO9227, JIS Z 2371 and ASTM G85.
Salt spray testing is popular because it is relatively inexpensive, quick, well standardized, and reasonably repeatable. Although there may be a weak correlation between the duration in salt spray test and the expected life of a coating in certain coatings such as hot dip galvanized steel, this test has gained worldwide popularity due to low cost and quick results.
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 a changing climate of acidified synthetic seawater spray, followed by a high humidity, both at an elevated temperature.
This test is also referred to as a SWAAT test. Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises the following 2 part repeating cycle. 30 minutes exposure to a continuous indirect spray of synthetic seawater solution, prepared in accordance with the requirements of the test standard and acidified (to pH 2.8 to 3.0) by the addition of acetic acid.
This spray is set to fall-out on to the specimens at a rate of 1.0 to 2.0ml/80 cm²/hour. This is followed by 90 minutes exposure to a high humidity climate of above 98%RH. The entire test cycle is at a constant chamber temperature of +49C (may be reduced to +24 to +35C for organically coated specimens). The number of cycle repeats and therefore the test duration is variable
1, Chamber material is made of P.V.C Sheet, sturdily and will not be out of shape.
2, Test chamber is heated from five directions to ensure the temperature is uniformity distributed.
3, Spray nozzle is specially made, enable to spray the salt water with considerable speed, then falls on the surface of samples.
4, Hot and moist air keeps the humidity in the test chamber conforms testing request.
5, High precision P.I.D. temperature controller limits the temperature difference within the range of ±0.1℃.
Please Note Small Type of 60 and 90 do not meet standard of ASTM B117.
