1.1 本规程涵盖了几类工业化学品的取样程序。它还包括确定此类样本数量和位置的建议，以确保其根据公认的概率抽样原则代表批次。 1.2 尽管本规程描述了散装或包装中各种液体、固体和泥浆的采样具体程序，但这些建议仅概述了应遵守的原则。它们不应优先于其他ASTM产品或方法标准中包含的具体采样说明。 1.3 这些程序包括以下内容: 小节 统计注意事项 7 – 11 简单液体 12 – 27 固体 28 – 35 泥浆 36 – 41 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。 第节给出了具体的预防说明 6. , 19 , 20 , 30 , 34 和 37 . 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 需要工业化学品的代表性样品来确定化学和物理性质，这些化学和物理性质用于确定标准体积、价格以及是否符合商业和监管规范。 5.2 取样的目的是从容器内的选定区域获得一小部分（点样）材料，该区域代表该区域的材料，或者在连续或所有水平样品的情况下，其成分代表容器中的总材料。 可以组合一系列斑点样本以创建代表性样本。 5.3 手动和自动采样注意事项- 选择手动或自动取样装置是建立适用于本实施规程范围内所有条件下的取样计划的一部分，前提是遵循了正确的取样程序。这两种类型的取样通常用于液体、固体和泥浆取样，需要遵守以下要求: 5.3.1 必须选择适当的采样频率。 5.3.2 支持手动或自动取样系统的设备可以从商业上获得，根据本规程中提出的设计制造，或根据需要进行制造，以满足工艺设计或其他特定要求。 5.3.3 必须定期维护采样设备，并严格遵守所采用的采样计划。

1.1 This practice covers procedures for sampling several classes of industrial chemicals. It also includes recommendations for determining the number and location of such samples, to ensure their being representative of the lot in accordance with accepted probability sampling principles. 1.2 Although this practice describes specific procedures for sampling various liquids, solids, and slurries, in bulk or in packages, these recommendations only outline the principles to be observed. They should not take precedence over specific sampling instructions contained in other ASTM product or method standards. 1.3 These procedures are covered as follows: Sections Statistical Considerations 7 – 11 Simple Liquids 12 – 27 Solids 28 – 35 Slurries 36 – 41 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. Specific precautionary statements are given in Sections 6 , 19 , 20 , 30 , 34 and 37 . 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 Representative samples of industrial chemicals are required for the determination of chemical and physical properties which are used to establish standard volumes, prices, and compliance with commercial and regulatory specifications. 5.2 The objective of sampling is to obtain a small portion (spot sample) of material from a selected area within a container which is representative of the material in the area or, in the case of running or all-level samples, a sample whose composition is representative of the total material in the container. A series of spot samples may be combined to create a representative sample. 5.3 Manual and Automatic Sampling Considerations— The selection of manual or automatic sampling devices is part of establishing a sampling plan applied under all conditions within the scope of this practice provided that the proper sampling procedures are followed. Both types of sampling are commonly used for liquid, solid, and slurry sampling and require adherence to the following: 5.3.1 An adequate frequency of sampling must be selected. 5.3.2 The equipment to support manual or automatic sampling systems may be obtained commercially, fabricated from the designs presented in this practice, or constructed as needed to satisfy process design or other specific requirements. 5.3.3 The sampling equipment must be maintained on a regular basis, and the sampling plan adopted must be strictly followed.
