Peel Resistance of Adhesives (T-Peel Test) ASTM D1876

Peel Resistance of Adhesives (T-Peel Test) ASTM D1876

Using a T-type specimen, the ASTM D1876 test method is designed to determine the relative peel resistance of adhesive connections between flexible adherents. The T-peel test is the most extensively used peel test since it only employs one layer of metal.

    Scope:

    The T-peel test (ASTM D1876) determines how much force is needed to gradually separate two bound, flexible adherents. Peel tests intended for flexible adhesives are designed to measure resistance to highly localized stresses. A peel test also measures a material’s adhesive strength of the adhesive bonding strength between two materials. The T-peel test is commonly used to assess adhesively bonded systems’ surface treatments and environmental endurance. 

    Variations in test specimen preparation, such as adhesive curing, adhesive thickness, adherents,  and conditioning, reveal opportunities for process and application improvement

    Procedure:

    According to ASTM D1876, the test specimen’s bent, unbonded ends are gripped in the tension testing machine’s test grips. A steady head speed of 254 mm (10 in.)/min is used to attach the load. The bond will separate at a rate of 127 mm (5 in.) per minute at this speed. During the peel test, an autographic recording of load vs head movement or load versus distance peeled is made.  After that, the peel resistance of the bond line for at least a 127-mm (5-in.) length after the initial peak is determined. 

    Specimen size:

    As per ASTM D1876, specimens are cut from a T-peel panel to 25.4 mm (1.0 in) long * 300 mm  (12 in) wide.  

    Data:

    Peel load is reported in pounds per inch of the specimen width required to separate the adherents.
