Salt Spray Environmental Test Chamber for Corrosion Resistance of
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
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
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.
PSA D17 1058 Neutral salt spray test, Can be used to test the relative
resistance to corrosion of coated metallic specimens, when exposed
to a salt spray climate at an elevated temperature.
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℃.
