1.1 本试验方法包括根据标准参考系统测定硫化（热固性）橡胶、热塑性弹性体、弹性体和类似材料的耐磨性。使用一组标准参考化合物计算相对耐磨性。这些参考化合物还用于在允许范围内确定试验中使用的切割刀的相对性能。 1.2 用于测定质量、力或尺寸的所有材料、仪器或设备应可追溯至国家标准与技术研究所， 2. 或其他国际公认的性质类似的组织。 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 本试验方法可用于估算标准材料的相对耐磨性，如 1.1 . 部分由于使用条件的广泛变化，因此未给出或暗示该加速试验与使用性能之间的相关性。 4.2 配方中给出了混合和固化规范 附件A1 一旦制备，即称为校准化合物。这些校准化合物可用于确定本试验方法中所述切割刀的性能状态。 4.3 切割刀的性能也可以通过定期确定其尺寸来确定，如中所述 6.1.7 . 4.4 校准化合物用作参考标准，可与由标的材料的体积损失确定的耐磨性进行比较。 4.5 一旦使用该方法确定了特定材料的耐磨性，所获得的结果可作为实验室之间或客户与供应商之间商定的相同材料未来比较分析的基础。

1.1 This test method covers the determination of the abrasion resistance of vulcanized (thermoset) rubbers, thermoplastic elastomers, and elastomeric and similar materials to a standardized reference system. A standardized set of reference compounds is used to calculate relative abrasion resistance. These reference compounds are also used to determine the relative performance, within a permissible range, of the cutting knives used in performing the test. 1.2 All materials, instruments, or equipment used for the determination of mass, force, or dimension shall have traceability to the National Institute for Standards and Technology, 2 or other internationally recognized organization parallel in nature. 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 This test method may be used to estimate the relative abrasion resistance of subject materials as described in 1.1 . No correlation between this accelerated test and service performance is given or implied, due, in part, to the widely varying nature of service conditions. 4.2 The formulas, for which the mixing and curing specifications are given in Annex A1 , once prepared, are referred to as calibration compounds. These calibration compounds may be used to determine the performance status of the cutting knives as described in this test method. 4.3 The performance of the cutting knives may also be determined by periodically determining their dimensions as described in 6.1.7 . 4.4 The calibration compounds are used as reference standards to which the abrasion resistance, determined by volume loss of a subject material, may be compared. 4.5 Once the resistance to abrasion is established, using this methodology, for a specific material, the results achieved may be used as a basis for future comparative analysis of identical materials, either as agreed upon between laboratories, or between customer and supplier.
