Standard Test Method for Scour of Hydrodynamic Separators and Settling Devices 流体动力分离器和沉降装置冲刷的标准试验方法
发布日期: 2024-01-01
1.1 该试验方法包括水动力雨水分离器和地下沉降装置的试验,因为它与先前捕获的沉积物的再悬浮和冲刷(冲刷)的测量有关。 1.2 测试的单元应具有通常制造和可供购买的尺寸。为了便于测试,如果操作部件是全尺寸的,具有相同的尺寸、配置和商用材料,则允许用替代材料代替测试单元的外壳和结构部件。不允许使用比例模型。 1.3 该试验方法提供了一种评估先前用制造的处理装置(MTD)捕获的悬浮固体的截留率的方法,该处理装置作为离线或在线处理装置沿着雨水排放管道放置。 它提供了评估MTD是否适合在离线或在线条件下安装的标准。 1.4 该试验方法提供了评估离线和在线条件下冲刷潜力的方法。 1.5 单位-- 以英寸磅为单位的数值应视为标准,但建立和报告沉积物浓度和颗粒尺寸的方法除外。按照惯例,仅以mg/L为单位描述沉积物浓度,以mm或μm为单位描述颗粒尺寸,这两种单位均为国际单位制。括号中给出的国际单位制是数学转换,仅供参考,不被视为标准单位。以英寸磅单位以外的单位报告试验结果不应视为非- 符合此测试方法。 1.6 该测试方法可能受到质量保证项目计划、特定验证协议或具有管辖权的机构(AHJ)设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 1.7 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、特定验证协议或具有管辖权的机构(AHJ)设定的特定要求的约束。建议对上述一项或全部内容进行审查,以确保合规性。 1.8 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。 1.9 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 该测试方法提供了测试结果,用于评估在线和离线配置下MTD内捕获的沉积物的冲刷潜力。 5.2 该试验方法将确定MTD是否能满足相关验证协议或当地AHJ要求规定的冲刷性能要求。
1.1 This test method covers the testing of hydrodynamic stormwater separators and underground settling devices as it relates to the measurement of the resuspension and washout (scour) of previously captured sediment. 1.2 Units tested shall be of a size commonly manufactured and available for purchase. In order to facilitate testing it is permissible to substitute alternate materials for the housing and structural components of the test units if operational components are at full size, with identical dimensions, configurations and materials specified for commercial use. Scale models are not permissible. 1.3 The test method provides a means of evaluating retention of suspended solids previously captured with a manufactured treatment device (MTD) that is placed as an offline or online treatment device along storm drain pipe lines. It provides criteria in which to evaluate whether the MTD is appropriate for installation in offline or online conditions. 1.4 This test method provides the means for evaluating the scour potential for both offline and online conditions. 1.5 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. 1.6 This test method may be subject to specific requirements set by a Quality Assurance Project Plan, a specific verification protocol, or Authority Having Jurisdiction (AHJ). It is advised to review one or all of the above to ensure compliance 1.7 Acceptance of test results attained according to this specification may be subject to specific requirements set by a Quality Assurance Project Plan, a specific verification protocol, or Authority Having Jurisdiction (AHJ). It is advised to review one or all of the above to ensure compliance. 1.8 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. 1.9 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 provides test results for evaluating the potential for scour of sediment captured within a MTD in online and offline configurations. 5.2 This test method will determine if an MTD can meet the scour performance requirements prescribed by an associated verification protocol or local AHJ requirements.
