1.1 本试验方法涵盖在处理固体废物的装置中测定所需产品的回收率，以浓缩相关成分。恢复取决于一个输出流（接受）中所需成分的数量，而不是另一个输出流（拒绝）。该计算结果确定了当与测试方法中所述的产品纯度测量相结合时，成分分离的有效性 E889 . 1.2 以国际单位制表示的数值应视为标准值。 本标准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。 具体预防信息见第节 6. . 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====== 5.1 本试验方法用于记录固体废物资源回收分离器在所需工艺流中捕获感兴趣成分的能力。 5.2 如试验方法所述，以这种方式确定的回收率与产品纯度一起使用 E889 .

1.1 This test method covers the determination of the recovery of a desired product in a device processing solid waste for the purpose of concentrating a component of interest. The recovery is determined with respect to the amount of the desired component in one output stream (accepts) as opposed to another output stream (rejects). The results of this calculation determine the effectiveness of component separation when coupled with a measure of product purity as described in Test Method E889 . 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. Specific precautionary information is given in Section 6 . 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 ====== 5.1 This test method is used to document the ability of a solid waste resource recovery separator to capture the component(s) of interest in the desired process stream. 5.2 The recovery determined in this way is used in conjunction with the purity of the product, as described in Test Method E889 .
