    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 the 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-AB 1, for recycled ferrous abrasives in SSPC-AB 2, for new ferrous abrasives in SSPC-AB 3, and for recyclable encapsulated abrasive media in SSPC-AB 4.

    4.3 Other contaminants in abrasive such as chemical contaminants or particulate matter require other methods for detection such as Test Method D4940 for conductive-potential, ionic contaminants. Because Test Method D4940 specifies a different ratio of abrasive to water and requires the use of higher purity water, the solution resulting from the evaluation of the oil in abrasive shall not be used for the evaluation in accordance with 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, blast and paint shop or steel 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
