ASTM F148-95

Standard Test Method for Binder Durability of Cork Composition Gasket Materials

SCOPE
1.1 This test method covers three procedures for determination of the binder durability of cork-containing materials.  
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.
