ASTM-D7575 › Standard Test Method for Solvent-Free Membrane Recoverable Oil and Grease by Infrared Determination
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the determination of oil and grease in water extracted with an infrared-amenable membrane and measured by infrared transmission through the membrane.
1.2 This method defines oil and grease in water as that which is extractable in the 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 and health practices and determine the applicability of regulatory limitations prior to use.
Significance and Use
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.
Regulations and standards have been established that require monitoring of oil and grease in water and wastewater.
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.
