SALT SPRAY CORROSION TEST
SALT SPRAY CORROSION TEST CHAMBERS :: ASTM B 117/ASTM G 85 (ALL ANNEX)/ ASTM D 2247
SEWMC02(200 lit.assembly)
SEWMC03(400 lit.assembly)
The ASTM B117 test apparatus for salt spray testing corrosion behavior of coatings & paints under salt spray conditions with specified temperature &humidity conditions. The apparatus provides controlled corrosive environment. The test introduces a spray in close chamber where specimens are exposed at specific locations and angles. The concentration of the NaCl solution ranges from 3.5 to 20%. Hot, humid air is created by bubbling compressed air through a bubble (humidifying) tower containing hot de-ionized water. The hot, humid air and the salt solution are mixed at the nozzle; it is atomized into acorrosive fog. This creates a 100% relative humidity condition in the exposure zone. This helps in producing relative corrosion resistance information for specimens of metals and coated metals exposed in the test chambers.
