Salt Spray Fog Testing

ASTM B117-03 Standard method of salt spray (fog) testing. 

These standards, under the jurisdiction of ASTM Subcommittee GO 1.05 on Laboratory Corrosion Tests, are not described in Chapter 12. Practice G 85-02el provides a more corrosive environment than Method B 117-03, generally using acids and SO2 to supplement the salt.

Panels of high strength aluminum alloy (7075-T6) were used in this study. The panels were approximately 10 x 3 x 0.032 inch (25 x 7.5 x 0.08 cm) in size. The test environments for coating evaluation were (1) a 5% NaCl spray (fog) chamber according to ASTM Standard Method of Salt Spray (Fog) Testing (B117-73), and (2) a modified 5% NaCl/S02 spray (fog) chamber with SO gas introduced periodically - ASTM Standard Practice for Modified Salt Spray (Fog) Testing (G85-84(A4)). In the latter case, a constant spray of 5% NaCl was maintained in the chamber and SO2 was introduced for one hour four tines a day (every 6 hours)( ). Coated test panels were examined for corrosion after one- and two- eek exposure periods.

Comparisons of the results of laboratory corrosion tests with damage sustained in use have revealed differences in corrosion and corrosion products. For example, the constant salt spray fog test leads to a different type of rust formation than that produced by natural weathering, with its alternating damp and dry periods. Test cycles have therefore been developed in which the individual stresses are applied in sequence. A good correlation with natural corrosion in automobiles was demonstrated in the VDA alternating test. The sample is subjected to salt spray fog for 24 h, followed by four 24-h cycles each consisting of 8 h at 40°C and 100% relative...

The salt water immersion test (SWI) and the standard salt spray (fog) test (SS) were conducted for both ISPCs and control baking enamels applied on bare CRS, iron phosphated B-1000, and BD+P60 panels. The painted coupons of about 1.0 mil dry film thickness cured at 163 C for 15 minutes were X-cut through the film to the substrate and then either immersed in a 3% NaCI solution (SWI test) or subjected to a continuous salt-solution spray in a test chamber (SS test). After a specified duration of testing, the specimens were removed from the salt solution, and the coated surface was immediately dried. A DUCK brand tape (Manco, Inc., Westlake, OH) was applied over the X-cut and then removed, and the protective performance was...
