1.1 This test method covers the determination of the relative peel resistance of cohesive or adhesive bonds between two adherends when tested under specified preparation and testing conditions.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are English units provided for information purposes 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 Use this test method for acceptance and process control testing. This test method may be used as an alternative to Test Method D1876 when the bond strength is sufficiently high that failure of the pulling tabs may occur before peeling initiates. This test method extends the bond strength measurement range by limiting the bend radius of the sample to concentrate the peeling action at the bond line. The test fixture also uses a smaller specimen size than Test Method D1876.
