1.1 本试验方法描述了通过人工分拣测量未经处理的城市固体废物（MSW）成分的程序。本试验方法适用于基于在至少一周的选定时间段内收集和手动分拣大量废物样本来确定MSW的平均成分。 1.2 该测试方法包括收集未处理废物的代表性分类样本、将废物手动分类为单个废物成分、数据减少和结果报告的程序。 1.3 该试验方法可应用于垃圾填埋场、废物处理和转化设施以及转运站。 1.4 以英寸磅为单位的数值应视为标准。括号中给出的值仅供参考。 1.5 本标准并不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。 有关具体的危险说明，请参阅第节 6. . 1.6 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 废物成分信息具有广泛的应用，可用于固体废物规划、废物管理设施设计以及建立参考废物成分以用作设施合同和验收测试计划中的基线标准等活动。 4.2 该方法可用于通过废物样品的选择和手动分拣来定义和报告MSW的成分。 在适用的情况下，应注意考虑废物的来源和季节变化。 4.3 在进行废物成分分析后，为了与资源回收设施的规划、管理、设计、测试和运营相关的目的，可以对废物成分或废物成分混合物的代表性样本进行实验室分析。

1.1 This test method describes procedures for measuring the composition of unprocessed municipal solid waste (MSW) by employing manual sorting. This test method applies to determination of the mean composition of MSW based on the collection and manual sorting of a number of samples of waste over a selected time period covering a minimum of one week. 1.2 This test method includes procedures for the collection of a representative sorting sample of unprocessed waste, manual sorting of the waste into individual waste components, data reduction, and reporting of the results. 1.3 This test method may be applied at landfill sites, waste processing and conversion facilities, and transfer stations. 1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 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. For specific hazard statements, see Section 6 . 1.6 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 Waste composition information has widespread applications and can be used for activities such as solid waste planning, designing waste management facilities, and establishing a reference waste composition for use as a baseline standard in both facility contracts and acceptance test plans. 4.2 The method can be used to define and report the composition of MSW through the selection and manual sorting of waste samples. Where applicable, care should be taken to consider the source and seasonal variation of waste. 4.3 After performing a waste composition analysis, laboratory analyses may be performed on representative samples of waste components, or mixtures of waste components, for purposes related to the planning, management, design, testing, and operation of resource recovery facilities.
