ASTM D6136-97

Standard Test Method for Kerosene Number of Unsaturated (Dry) Felt by the Vacuum Method

SCOPE
1.1 This test method covers the determination of the relative saturating capacity of unsaturated (dry) felt papers used in roofing.
1.2 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.
