1.1 本试验方法包括在室温下测定耐火砖的相对耐磨性。该试验方法也适用于可浇铸耐火材料（参见公制尺寸，实践 C861 和实践 C865 )和塑料耐火材料（见实践 C1054 ). 1.2 单位- 当数值以国际单位制和英寸-磅单位表示时，这些单位应单独视为标准。每个系统中规定的值可能不是精确的等效值；因此，独立使用每个系统。将两个系统的值合并可能会导致不符合标准。作为惯例，一些数值仅以国际单位制表示，并允许比较结果。 包括磨损介质重量（克）、试样重量（克）、磨损引起的试样重量损失（克）和由此产生的体积损失（立方厘米）。 1.3 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。 1.4 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 本试验方法测量了各种耐火材料样品在室温标准条件下的相对耐磨性。 4.2 耐火材料的耐磨性表明其适合在磨损环境中使用。 4.3 由于所遇到的条件不同，通过该试验方法获得的结果可能不同于在使用中获得的结果。

1.1 This test method covers the determination of relative abrasion resistance of refractory brick at room temperature. This test method can also be applied to castable refractories (see Metric Dimensions, Practice C861 and Practice C865 ) and plastic refractories (see Practice C1054 ). 1.2 Units— When values are stated in both SI and inch-pound units, the units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, use each system independently of the other. Combining values from the two systems may result in nonconformance with the standard. Several values are stated only in SI units as a matter of convention and to permit comparison of results. Included are the abrading media weight (grams), specimen weight (grams), specimen weight loss due to abrasion (grams), and the resultant volume loss (cubic centimeters). 1.3 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. 1.4 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 This test method measures the relative abrasion resistance of various refractory samples under standard conditions at room temperature. 4.2 The abrasion resistance of a refractory material provides an indication of its suitability for service in abrasive environments. 4.3 The results obtained by this test method could be different than those obtained in service because of the different conditions encountered.
