ASTM D7575-11(2017)

Standard Test Method for Solvent-Free Membrane Recoverable Oil and Grease by Infrared Determination

SIGNIFICANCE AND USE
5.1 The presence and concentration of oil and grease in domestic and industrial wastewater is of concern to the public because of its deleterious health, environmental, safety, and aesthetic effects.  
5.2 Regulations and standards have been established that require monitoring of oil and grease in water and wastewater.4
Note 1: Different oil and grease materials may have different infrared absorptivities. Certain materials, such as synthetic silicone-based or perfluorinated oils, may have absoptivities inconsistent with those of naturally occurring oil and grease materials. Caution should be taken when testing matrices suspected of containing proportions of these materials. In such cases, laboratory spike samples, laboratory check samples, equivalency testing, or combinations thereof, using these materials in question may be appropriate.
SCOPE
1.1 This test method covers the determination of oil and grease in produced and waste water samples over the concentration range outlined in Table 1 that can be extracted with an infrared-amenable membrane and measured by infrared transmission through the membrane. (A) MDL and recommended reporting range determined by 12.4, which follows the Code of Federal Regulations, 40 CFR, Part 136, Appendix B; limits should be determined by each operator.  
1.2 This test method defines oil and grease in water as that which is extractable in this test method and measured by infrared transmission.  
1.3 The method detection limit (MDL) and recommended reporting range are listed in Table 1.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 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.  
1.6 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.
