1、Designation:D757511(Reapproved 2017)Standard Test Method forSolvent-Free Membrane Recoverable Oil and Grease byInfrared Determination1This standard is issued under the fixed designation D7575;the number immediately following the designation indicates the year oforiginal adoption or,in the case of re
2、vision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the determination of oil andgrease in produced and waste water samples over the
3、concen-tration range outlined in Table 1 that can be extracted with aninfrared-amenable membrane and measured by infrared trans-mission through the membrane.1.2 This test method defines oil and grease in water as thatwhich is extractable in this test method and measured byinfrared transmission.1.3 T
4、he method detection limit(MDL)and recommendedreporting range are listed in Table 1.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with
