ASTM G144-01(2014)

1.1This 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.

1.2This 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.

1.3This 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.
