ASTM D3525-04
Historical Standard: ASTM D3525-04 Standard Test Method for Gasoline Diluent in Used Gasoline Engine Oils by Gas Chromatography
SUPERSEDED (see Active link, below)
ASTM D3525
1. Scope
1.1 This test method covers the use of gas chromatography to determine the amount of gasoline in used lubricating oils arising from their use in gasoline engines.
1.2 There is no limitation for the determination of the dilution range, provided that the amount of sample plus internal standard is within the linear range of the gas chromatograph detector.
1.3 This test method is limited to gas chromatographs equipped with flame ionization detectors and programmable ovens.
Note 1The use of other detectors and instrumentation has been reported. However, the precision statement applies only when the instrumentation specified is employed.
1.4 The applicability of this method to gelled used engine oils has not been adequately investigated in order to ensure compliance with the indicated repeatability and reproducibility. Gelled oils are defined as oils that develop structure on standing, but that return to their original fluidity with light agitation.
1.5 The values stated in SI units are to be regarded as the standard.
1.6 This standard does not purport to address all of the safety problems, 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.
