ASTM D3607-97

1.1 This test method describes a standardized procedure for removing volatile materials such as gasoline and water from used engine oils prior to further oil analysis. It also provides an estimate of the amount of such volatiles present in used engine oils.

1.1.1 Another estimate of the amount of volatile materials in used engine oils can be obtained by Test Method D3525, which determines the weight percent of the used oil sample boiling below the boiling point of n-tetradecene. In any case of dispute, the amount of volatiles as determined by Test Method D3525 shall be considered the referee value.

1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.

1.3 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 consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
