1.1 本标准的范围是为雨水控制措施（SCM），特别是人工雨水处理装置（MTD）的评估提供测试标准，以清除大于5 在实验室环境中，至少在两个维度上为mm。本标准的使用与适当的验证程序相结合，允许发布经验证的报告，以便获得具有管辖权的机构（AHJ）的认证。 1.2 就本方法而言，垃圾捕获装置（TCD）是一种SCM，具有捕获和保留垃圾和/或碎屑的能力。 这可能是该装置的主要目的，也可能是主要设计为流体动力分离器（HDS）或用于捕获沉积物颗粒的过滤器的装置的次要特征。本协议不涉及此类装置的沉积物清除。 1.3 单位- 除确定和报告沉积物浓度和粒度的方法外，以英寸-磅单位表示的值应视为标准值。按照惯例，沉积物浓度以mg/L表示，颗粒大小以mm或μm表示，两者均为国际单位制。 括号中给出的国际单位制单位为数学转换，仅供参考，不视为标准单位。以英寸磅单位以外的单位报告试验结果不得视为不符合本试验方法。 1.4 根据本规范获得的测试结果的验收可能受到质量保证项目计划（QAPP）、特定验证协议或AHJ规定的特定要求的约束。建议审查上述一项或全部内容，以确保合规性 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建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 本标准与验证协议一起使用，可用于获得从雨水径流中清除垃圾和/或碎屑的认证，以满足监管和许可要求。

1.1 The scope of this standard is to provide test criteria for the evaluation of Stormwater Control Measures (SCM), especially Manufactured stormwater Treatment Devices (MTDs), for the removal of trash and/or debris greater than 5 mm in at least two dimensions in a laboratory setting. The use of this standard in conjunction with an appropriate verification program allows for the publication of verified reporting for use in gaining certification by Authorities Having Jurisdiction (AHJs). 1.2 For the purpose of this method, a Trash Capture Device (TCD) is an SCM that has the capacity to capture and retain trash and or debris. This may be the primary objective of the device or it may be a secondary feature of a device designed primarily as a Hydrodynamic Separator (HDS) or a filter for capturing sediment particles. This protocol does not address the sediment removal of such devices. 1.3 Units— The values stated in inch-pound units are to be regarded as standard, except for methods to establish and report sediment concentration and particle size. It is convention to exclusively describe sediment concentration in mg/L and particle size in mm or μm, both of which are SI units. The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard. Reporting of test results in units other than inch-pound units shall not be regarded as non-conformance with this test method. 1.4 Acceptance of test results attained according to this specification may be subject to specific requirements set by a Quality Assurance Project Plan (QAPP), a specific verification protocol, or AHJ. It is advised to review one or all of the above to ensure compliance 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. 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 ====== 5.1 This standard, used in conjunction with a verification protocol can be used to gain certification for the purposes of the removal of trash and/or debris from stormwater runoff in order to meet regulatory and permit needs.
