ASTM D1876 is used to determine the relative peel resistance of adhesive bonds between flexible adherends using a T-type sample. Manufacturers use this quality control standard in a variety of industries where relative peel resistance across individual samples or various adhesive forms is required.
Scope:
ASTM D1876 test is used to determine the relative peel resistance of adhesive bonds between flexible adherends through a T-type sample. This test measure is also known as a T-peel owing to the shape of two flexible adherends as they are taken apart. Manufacturers use this quality control standard in a variety of industries as it is mainly designed to establish relative peel resistance across individual samples or various adhesive forms.
Test Procedure:
A universal testing machine is used. Each end of the T-peel sample is clamped in separate test grips of the machine. The sample is separated at a rate of 127 mm (5.0 inch) /min for 5 inches length of the bond line as per the guidelines.
Specimen size:
Samples are cut from a T-peel panel to 25.4 mm (1.0 inch) long by 300 mm (12 inches) wide. Ten samples are tested.ASTM D882 uses 1-inch 6 inches strips are die cut from thin sheets or film.
