salt corrosion tester NSS ACSS Usage salt spray test chamber
USES
Thismachine has a standardized test method to check corrosion resistence of coated samples. Salt spray test
is an accelerated corrosion test that produces a corrosive attack to the coated samples in order to predict its
suitability in use as a protective finish. The appearance of corrosion products (oxides) is evaluated after a
period of time. Test duration depends on the corrosion resistance of the coating; the more corrosion resistant
the coating is, the longer the period in testing without showing signs of corrosion. Different coatings have
different behaviour in salt spray test and consequently, test duration will differ from one type of coating to
another.
Bo Nute principle draw salt water and then spray , atomization uniform , no crystallization of the blocking phenomenon , to ensure continuous testing , the compressed air nozzle on the way through it leading to the bubble column was wet , the corrosion solution and air nozzle atomized into a corrosive mist , inside the heater to maintain the temperature inside .
