Three methods of tested tested saline test chamber

Three methods for tested the test chamber Salt fog test ZUI routine test method is a neutral salt spray test, an acidic salt spray test, its test solution has a certain difference:

Test solution : PLUSMN ° C pH pH value of sodium chloride needs to be adjusted to 6.5-7.2, The acid and base can be used to commission the solution pH value .ph value needs to be in 23 [ , Glass electrode , . Test solution concentration is 50 5 . b. Acetate Spray Test (ASS Test) : pH pH of the sodium chloride solution , ] Ensure that the standard
, ,

to 3.3 PH , temperature is 23 , requires each liter 1 of acetic acid . PH The value needs to be in . . Test solution concentration is 50 Each liter. C. Copper accelerated acetate fog test (CASS test) Liquid: First , Each rising 0.26 apron, other requirementsStandard development.
