1.1 This test method provides a means for the identification of waterborne oil samples by the comparison of their infrared spectra with those of potential source oils.
1.2 This test method is applicable to weathered or unweathered samples, as well as to samples subjected to simulated weathering.
1.3 This test method is written primarily for petroleum oils.
1.4 This test method is written for linear transmission, but could be readily adapted for linear absorbance outputs.
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.
