    ASTM D7393

    Significance and Use

    4.1 Oil in abrasives can be transferred to the surface being cleaned, thus contaminating it. This can cause film defects, affect adhesion of the coating applied over it, and ultimate performance of the coating system.

    4.2 Oil in abrasives is one of the cleanliness tests required for mineral and slag abrasives in SSPC-AB1, for recycled ferrous abrasives in SSPC-AB2, and for new ferrous abrasives in SSPC-AB3.

    4.3 Other contaminants in abrasive such as chemical contaminants or particulate matter require other methods for detection such as Test Method D4940 for ionic contaminants. The ratio of abrasive to water is different for this test, so the solution from evaluating the oil in abrasive should not be used for Test Method D4940.

    1. Scope

    1.1 This practice is used to determine the presence of oil in abrasives used for abrasive blast cleaning.

    1.2 The procedure can be used in the laboratory, field or fabrication shop.

    1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

    1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
