Standard Test Method for Finite Flash Point Determination of Liquid Wastes by Small-Scale Closed Cup Tester 用小型闭杯试验仪测定液体废物的有限闪点的标准试验方法
发布日期: 2018-03-15
1.1 本试验方法涵盖了-20至70范围内的闪点试验程序 °C,使用小型闭杯测试仪测量液体废物。 注1: 有些仪器不是为亚环境温度测试而设计的,因此测试范围将在20℃之间 °C和70 °C。 注2: 本试验方法不适用于形成表面膜的废液(见试验方法 D8175 用于通过彭斯基-马丁斯闭杯测试仪测定废物的有限闪点)。 1.2 单位- 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.3 本标准测量了液体废物(可能是任何废弃材料)的可燃性,其中可能包括二次材料- 规范产品和含有应急响应行动期间回收的游离液体的材料。本试验方法的结果可作为材料火灾风险评估的一部分,但用户有责任根据现行法规进行确定储存、运输、处理或处置所需的任何其他表征。 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。 警告语句贯穿始终。有关本试验方法中可能使用的认证标准物质(CRM)或二级工作标准(SWS)的信息,请参阅适用的安全数据表(SDS)。如果已知废物样品的某些成分,十二烷基硫酸钠也可能有用。 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 本程序旨在评估液体废物的可燃性。 5.2 闪点测量受控实验室条件下子样本对热量和点火源的响应。这只是在评估液体废物的整体易燃性危险时应考虑的众多特性之一。 5.3 闪点可以表示在相对不挥发或不易燃的材料中可能存在高挥发性和易燃材料。 5.4 本试验方法使用小样本体积(2 mL)和短测试时间(1 最小值)。
1.1 This test method covers the procedure for a flash point test, within the range of –20 to 70 °C, of liquid wastes using a small-scale closed cup tester. Note 1: Some apparatus are not designed for subambient temperature tests, so the testing range would be between 20 °C and 70 °C. Note 2: This test method is not applicable for liquid waste that forms a surface film (see Test Method D8175 for Finite Flash Point Determination of Wastes by Pensky-Martens Closed Cup Tester). 1.2 Units— The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.3 This standard measures the ignitability properties of liquid wastes (which may be any discarded material), which may include secondary materials, off-specification products, and materials containing free liquids recovered during emergency response actions. Results from this test method may be used as part of a fire risk assessment of the material, but it is the responsibility of the user to perform any additional characterization needed for determination of storage, transport, treatment, or disposal per current regulations. 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. Warning statements appear throughout. See applicable Safety Data Sheets (SDS) for information about certified reference materials (CRMs) or secondary working standards (SWSs) that may be used in this test method. SDS may also be useful if some components of the waste sample are known. 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 This procedure is intended to be used to evaluate the ignitability of liquid wastes. 5.2 Flash point measures the response of the subsample to heat and an ignition source under controlled laboratory conditions. It is only one of a number of properties that shall be considered in assessing the overall flammability hazard of a liquid waste material. 5.3 Flash point can indicate the possible presence of highly volatile and flammable materials in a relatively nonvolatile or nonflammable material. 5.4 This test method uses a small sample volume (2 mL) and short test time (1 min).
