Standard Test Method for Contact Compatibility Between Asphaltic Materials (Oliensis Test)
SCOPE
1.1 This test method provides a means for evaluating contact compatibility between asphaltic materials. It is generally used to determine compatibility between the saturant and coating used in the manufacture of prepared roofing's. Coating and saturant will be referred to, but comparable asphaltic materials may be tested where this test procedure seems applicable.
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.
