1.1本试验方法包括使用总碳测定水样品中的残留污染( 总费用 )分析仪。当与规程G131和G136一起使用时，该程序可用于确定需要高清洁度的系统、部件和材料（如氧气系统）的清洁度。本程序仅适用于水基清洗和取样方法。 1.2本试验方法不适用于评估颗粒污染物，或不溶于水或不与水形成乳液的污染物。 1.3 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。 ====意义和用途====== 5.1预计本试验方法适用于定量测定用于清洁、提取或取样需要高度清洁的零件、组件、材料或系统（即氧气系统）的水中总碳。

1.1 This test method covers the determination of residual contamination in an aqueous sample by the use of a total carbon ( TC ) analyzer. When used in conjunction with Practice G131 and G136, this procedure may be used to determine the cleanliness of systems, components, and materials requiring a high level of cleanliness, such as oxygen systems. This procedure is applicable for aqueous-based cleaning and sampling methods only. 1.2 This test method is not suitable for the evaluation of particulate contamination, or contaminants that are not soluble in or that do not form an emulsion with water. 1.3 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. ====== Significance And Use ====== 5.1 It is expected that this test method will be suitable for the quantitative determination of total carbon in water that has been used to clean, extract, or sample parts, components, materials, or systems requiring a high degree of cleanliness, that is, oxygen systems.
