【国外标准】 Standard Test Method for Determination of Residual Contamination of Materials and Components by Total Carbon Analysis Using a High Temperature Combustion Analyzer

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.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.
