Salt Spray Fog Corrosion Testing Equipment Climate Chamber With
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℃.
