1.1 该测试方法用于测量资源回收单元操作或一系列单元操作的吞吐量或质量流量。 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。 1.2.1、 例外情况- 段落 9.1.2 表示颗粒尺寸大于90的样品的当量（磅） 毫米。 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。 具体预防信息见第节 7. 。 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====== 5.1 该测试方法用于记录工厂中资源回收装置运行的质量流速，并作为将运行与设计目标联系起来的一种手段。 5.2 该试验方法还与材料分离器性能的测量（特别是回收率和纯度）结合使用。因此，通常不应通过对进料进行采样来测量吞吐量，因为这可能会改变其性能。不进行分离的加工设备可以在进料流或产物流中取样。

1.1 This test method is for measuring the throughput, or mass flow rate, of a resource-recovery unit operation, or series of unit operations. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.2.1 Exception— Paragraph 9.1.2 indicates the equivalent weight in pounds for samples with particle size greater than 90 mm. 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 7 . 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 mass flow rate of a resource recovery unit operation in a plant and as a means of relating operation to design objectives. 5.2 This test method is also used in conjunction with measurements of the performance of materials separators (particularly recovery and purity). As such, throughput should not generally be measured by sampling the feed since this may change its performance. Processing equipment that does not perform separations can be sampled at either the feed or product streams.
