It is based on experience in use of the method with standard by cm 4- by 6-in. At the option of the inspector, this difficulty may be handled as follows: If dirt, salt deposits, and so forth, make it impractical to inspect them, panels may be sponged with a mild soap solution followed by water rinse; but no pressure should be exerted in this procedure such as would tend to upgrade the rating by, for example, cleaning off rust or rust stain.
Types of Defects 4. Typical decorative deposits exposed to marine atmospheres often tend to fail by crater rusting, whereas in industrial atmospheres, they are more likely to exhibit pinpoint rusting; and the latter atmosphere also tends to be more severe with regard to degradation of the coating system but somewhat less severe with regard to basis metal corrosion.
