Laboratory Accelerated Corrosion Salt Fog Test Chamber ASTM B117
for Electroplating
Brief Introduction:
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.
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. For example,
pre-treated + painted components must pass 96 hours Neutral Salt
Spray, to be accepted for production.
Failure to meet this requirement implies instability in the
chemical process of the pre-treatment, or the paint quality, which
must be addressed immediately, so that the upcoming batches are of
the desired quality. The longer the accelerated corrosion test, the
longer the process remains out of control, and larger is the loss
in the form of non-conforming batches.
The principle application of the salt spray test is therefore
enabling quick comparisons to be made between actual and expected
corrosion resistance. Most commonly, the time taken for oxides to
appear on the samples under test is compared to expectations, to
determine whether the test is passed or failed. For this reason the
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.
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℃.
