1.1 本试验方法包括测定有机液体危险废物（OLHW）中不溶性悬浮固体物质的近似量。 1.2 本试验方法旨在用于在确定OLHW的材料处理特性和燃料质量时近似计算不溶性悬浮固体的量。其目的不是取代测定总固体的更复杂程序。 1.3 单位- 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。 1.4 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。 1.5 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 高百分比的不溶性悬浮固体物质会在散装OLHW卸载过程中造成泵送、过滤或研磨困难，并可能导致加工设备过度磨损。高固体分还会降低储罐中搅拌的有效性，从而降低混合溶液的质量和稠度。除了提议将废物用作燃料的活动外，回收行业（大量处理的溶剂、油漆和其他材料）也关注这些问题。

1.1 This test method covers the determination of the approximate amount of insoluble, suspended solid material in organic liquid hazardous waste (OLHW). 1.2 This test method is intended to be used in approximating the amount of insoluble, suspended solids in determining the material-handling characteristics and fuel quality of OLHW. It is not intended to replace more sophisticated procedures for the determination of total solids. 1.3 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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. 1.5 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 A high percentage of insoluble, suspended solid material can create pumping, filtering, or grinding difficulties in the off-loading of bulk shipments of OLHW and can contribute to excessive wear on processing equipment. High solids can also decrease the quality and consistency of commingled solutions by decreasing the effectiveness of agitation in storage tanks. These issues are of concern to the recycling industries (solvents, paints, and other materials handled in significant quantities) in addition to those activities that propose to use the waste as a fuel.
