Abrasion cycle n. The number of abrading motions or cycles to which a test specimen is subjected in a test of abrasion resistance. Paint and coating testing manual (Gardner-Sward handbook). MNL 17, 14th edn. ASTM, Conshohocken, PA, 1995. 

The salt spray test was adopted by ASTM in 1939 after considerable developmental work by the National Bureau of Standards [2]. It has widespread use in many industries, including automotive, aerospace, paints and coatings, etc. ASTM B 117 can be found as a reference in many material and performance standards as a stand-alone test or as part of other environmental conditions to which a specimen is subjected prior to acceptance. 

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...
