1.1 本试验方法包括使用总碳测定水样中的残余污染( 总费用 )分析仪。与Practice结合使用时 G131号 和 G136号 ，本程序可用于确定要求高清洁度的系统、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微粒污染，或不溶于水或不与水形成乳液的污染物。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 1.4 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 预计该试验方法将适用于定量测定用于清洁、提取或取样零件、部件、材料或要求高度清洁的系统（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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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 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.
