1.1 本规程用于确定喷砂清理用磨料中是否存在油。 1.2 该程序可用于实验室、现场、喷砂和喷漆车间或钢铁制造车间。 1.3 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 磨料中的油可以转移到被清洁的表面，从而污染表面。这可能会导致薄膜缺陷，影响涂层的附着力，以及涂层系统的最终性能。 4.2 磨料中的油是SSPC-AB 1中的矿物和矿渣磨料、SSPC-AB 2中的回收含铁磨料、SSPC-AB 3中的新含铁磨料以及SSPC-AB 4中的可回收封装磨料介质所需的清洁度测试之一。 4.3 磨料中的其他污染物，如化学污染物或颗粒物，需要其他检测方法，如测试方法 D4940 对于导电电位，离子污染物。因为测试方法 D4940 规定了不同的磨料与水的比例，并要求使用更高纯度的水，根据试验方法，评估磨料中的油时产生的溶液不得用于评估 D4940 .

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. ====== 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 .
