What are the challenges of peeling off adhesive in accordance with ASTM 1876?
- Reporting results in compliance with the standard
- Data rate used to capture peaks and troughs
- Eliminating slippage throughout the test
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.
What is Instron’s solutions?
1. In order for the reporting results to comply with testing standards, Bluehill Universal software will help users to do that. The software will be installed with configuration testing methods and supporting documentation to ensure that the test takers comply with the standards.

2. 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
3. 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.
