Salt Spray Corrosion Testing Cabinet Cyclic Chamber for NSS CASS Test Surface Coatings
Salt spray test is most often deployed in a quality audit role, where, for example, it can be used to check the effectiveness of a production process, such as the surface coating of a metallic part. The salt spray test has little application in predicting how materials or surface coatings will resist corrosion in the real-world, because it does not create, replicate or accelerate real-world corrosive conditions. Cyclic corrosion testing is better suited to this.
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.
