1.1 喷射杯磨损试验适用于流化催化裂化（FCC）催化剂、催化剂添加剂和催化材料。 1.2 文献中报道了其他粉末催化剂的应用。循环试验样品包括两个FCC催化剂和一个氧化铝粉末。 1.3 单位- 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 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====== 5.1 喷射杯磨损试验将估计流化催化裂化（FCC）催化剂、催化剂添加剂和催化材料的相对耐磨性。 5.2 该试验旨在模拟催化剂或添加剂在流化催化裂化装置中以加速速度发生的磨损。 5.3 该测试的数据可用于根据磨损率对催化剂进行分级。 5.4 该测试需要相对较小的样本量（5g[0.175 oz]），相对较短的分析时间（40min）。该测试应适用于需要快速周转时间的质量控制设施和样本材料有限的研发设施。

1.1 The jet cup attrition test is applicable to fluid catalytic cracking (FCC) catalysts, catalyst additives, and catalytic materials. 1.2 Applications for other powdered catalysts have been reported in the literature. The round robin test samples included two FCC catalysts and one powdered alumina. 1.3 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 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 ====== 5.1 The jet cup attrition test will provide an estimate of the relative attrition resistance of fluid catalytic cracking (FCC) catalyst, catalyst additives, and catalytic materials. 5.2 The test is designed to simulate the attrition a catalyst or additive undergoes in a fluid catalytic cracking unit but at an accelerated rate. 5.3 The data from this test can be used to rank catalyst according to attrition rate. 5.4 The test requires a relatively small sample size of 5 g [0.175 oz] and a relatively short analysis time of 40 min. This test should be useful to quality control facilities that require fast turnaround time and research and development (R&D) facilities that have limited sample material.
