1.1 这些试验方法适用于使用以下方法筛选废物、液体、污泥、半固体和固体中的活性硫化物: 小节 试验方法A-醋酸铅纸 9 – 14 试验方法B-气体检测管 15 – 19 1.2 这些试验方法不适用于确定活性硫化物的类型和浓度。 1.3 这些试验方法旨在作为初步试验，以补充可用于测定硫化物浓度的更复杂定量分析技术。这些测试方法为用户提供了在复杂技术不可用且废物总成分未知时筛选废物中潜在危险水平的活性硫化物的选项和能力。 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和健康实践，并确定监管限制的适用性。 第节给出了具体的危险信息 7. 和 11.3 . ====意义和用途====== 5.1 这些测试方法旨在用于废物处理、储存、处置和补救设施，以显示潜在危险硫化物的存在。 5.2 方法B:气体检测管- 该拟议的测试方法旨在测量从10个单位平方（例如100英尺）的接收或混合坑迁移到高度为10个单位（例如10英尺）的空气空间的气体 2. ). 本质上，大气总体积约为样品和测试溶液表面积的10倍。

1.1 These test methods are applicable to the screening of reactive sulfides in wastes, liquids, sludges, semisolids, and solids by using the following methods: Sections Test Method A—Lead Acetate Paper 9 – 14 Test Method B—Gas Detector Tube 15 – 19 1.2 These test methods are not applicable in determining the type and concentration of reactive sulfides. 1.3 These test methods are designed and intended as a preliminary test to complement the more sophisticated quantitative analytical techniques that may be used to determine sulfide concentration. These test methods offer, to the user, the option and the ability to screen waste for potentially hazardous levels of reactive sulfide when the sophisticated techniques are not available and the total waste composition is unknown. 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard information is given in Section 7 and 11.3 . ====== Significance And Use ====== 5.1 These test methods are intended for use by waste treatment, storage, disposal, and remedial facilities, in order to show the presence of potentially hazardous sulfide. 5.2 Method B: Gas Detector Tube— This proposed test method was designed to measure gases migrating into an air space at a height of 10 units (for example, 10 ft) from a receiving or mixing pit of 10 units square (for example, 100 ft 2 ). In essence, the total volume of the atmosphere is approximately 10 times the surface area of the sample and test solution.
