The salt spray tests are particularly useful for detecting discontinuities, such as pores and other defects in certain metallic, organic, anodic oxide and conversion coatings.

The test duration is 24?

The test ej shall be 48 h. During operation, the solution should be free from dust and should be isolated from ambient air to prevent the concentration of sodium chloride and the pH from fluctuating. D gives supplementary information needed for testing test panels with organic coatings. So if you want to know how to set up a salt spray cabinet or how to make the salt solution, then B is a reference. Unless otherwise specified or agreed, test panels with an organic coating to be tested shall be made from burnished steel complying with ISO?

It is sn that freshly prepared solution be used during each procedure for the removal of corrosion products.

It particularly applies to: Assessment of degree of delamination and corrosion around a scribe ISO Nevertheless, the method described gives a means of checking that the comparative quality of a metallic material, with or without corrosion protection, is maintained. Baffles may be used to prevent direct impact of the spray on the test specimens, and the use of adjustable baffles is helpful in obtaining uniform distribution of the spray within the cabinet.
