Standard Test Method for Evaporation Loss of Lubricating Oils by the Noack Method

SCOPE
1.1 This test method covers three procedures for determining the evaporation loss of lubricating oils (particularly engine oils). Procedure A uses the Noack evaporative tester equipment; Procedure B uses the automated non-Wood's metal Noack evaporative apparatus, and Procedure C uses Selby-Noack volatility test equipment. The test method relates to one set of operating conditions but may be readily adapted to other conditions when required.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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.  See Sections 8 and 18 and 6.1.1, 7.1, 7.5, 9.1, 10.3, and 17.1 for specific precautionary statements.
