ASTM D1876-08 T-Peel Test for Adhesives

ASTM D1876 covers the determination of the comparative peel or stripping characteristics of adhesive bonds.  This test is referred to as a “T-peel” test, because as the two flexible adherends are pulled apart, they form the shape of a “T”.  This test can be performed on both single and dual column frames, depending on the strength of the materials being tested.  

  

The challenges of testing to this standard are:

• Reporting results in compliance with the standard
• Data rate used to capture peaks and troughs
• Eliminating slippage throughout the test

Instron Solution:

• Reporting results in compliance with the standard– Bluehill^® Universal comes with pre-configured test methods and supporting documentation to ensure that you are testing according to ASTM D1876
• Data rate used to capture peaks and troughs – Instron’s 6800 series frames enable data capture of up to 2.5 kHz to ensure that all fast changing test events are captured.  Too low of a bandwidth may “dull” the system and lead to missed peaks and troughs, resulting in lower average strength values
• Eliminating slippage throughout the test – Pneumatic grips are a great choice for T-peel testing as they are able to maintain constant gripping pressure throughout the testing.  The pneumatic grips employ a patented “quick-change” jaw face design which enables operators to easily change jaw faces to accommodate the needs of their materials

It is important to review ASTM D1876-08(2015)e1 in order to fully understand the test setup, procedure, and results requirements.
