1.1 本试验方法通过旋转圆盘和使用磨料测量在给定条件下未上釉瓷砖磨损产生的体积损失，涵盖了深度磨料磨损。 1.2 以国际单位制表示的数值应视为标准。本标准中不包括其他计量单位。 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）。本标准的使用者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》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 4.1 该试验方法提供了测量地板覆盖物用无釉瓷砖潜在耐磨性的方法。该试验方法不考虑物理外观，但旨在测量耐久性。参见测试方法 C1027 用于测定釉面瓷砖的可见耐磨性。 4.1.1 参见测试方法 C501 用于确定深度磨损的替代方法。

1.1 This test method covers the deep abrasive wear by measuring the loss of volume resulting from abrasion of unglazed ceramic tile under given conditions by means of a rotating disc and the use of abrasive material. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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 provides the means to measure the potential resistance to wear of unglazed ceramic tile intended for floor coverings. This test method does not consider physical appearance but is intended to measure durability. See Test Method C1027 for the determination of visible abrasion resistance of glazed ceramic tile. 4.1.1 See Test Method C501 for an alternative method to determine deep abrasion.
