ASTM B117 Salt Spray Corrosion Tester,
Microcomputer Control Salt Fog Chamber
Salt Spray Fog Corrosion Testing Equipment Climate Chamber With Microcomputer Control
The salt spray (or salt fog) test is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings. Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.

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.
Salt spray testing is an accelerated corrosion test that produces a corrosive attack to coated samples in order to evaluate (mostly comparatively) the suitability of the coating for use as a protective finish. The appearance of corrosion products (rust or other oxides) is evaluated after a pre-determined period of time. 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. 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 Test Chambers offer the most realistic and dependable corrosion test, widely used to test corrosion resistance of automotive, paint, surface coating, chemical, aerospace, electronic, car industry, offshore and defense industries.
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℃.
