Power Saving CASS Salt Spray Corrosion Test Chamber With Polypropylene Shell

Power Saving CASS Salt Spray Corrosion Test Chamber with Polypropylene Shell

Brief Introduction:

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.

Salt Spray Test duration depends on the corrosion resistance of the coating; generally, the more corrosion resistant the coating is, the longer the period of testing before the appearance of corrosion/ rust. The salt spray test is one of the most widespread and long established corrosion tests.

Acetic Acid Salt Spray Test (non-cyclic) can be used to determine the relative resistance to corrosion of decorative chromium plating on steel and zinc based die casting when exposed to an acetic acid salt spray climate at an elevated temperature. This test is also referred to as an ASS test.

Test specimens are placed in an enclosed chamber and exposed to a continuous indirect spray of salt water solution, prepared in accordance with the requirements of the test standard and acidified (to pH 3.1 to 3.3) 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, in a chamber temperature of +35C. This climate is maintained under constant steady state conditions. The test duration is variable.

Most Salt Spray Chambers today are being used NOT to predict the corrosion resistance of a coating, but to maintain coating processes such as pre-treatment and painting, electroplating, galvanizing, and the like, on a comparative basis.

Features:

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℃.

Specifications:

Please Note Small Type of 60 and 90 do not meet standard of ASTM B117.
