T-Peel Resistance Test Fixture for Adhesives

ASTM D1876

T-Peel Resistance Test Fixture for Adhesives is based on ASTM D1876 standard, used to measure the adhesion strength of adhesive maeterial. ASTM D1876 peel strength test method is commonly used to measure the strength of adhesive bonds between two sealed materials, especially the closure seal of a sterile barrier package, such as a pouch or tray. The test is conducted by first cutting a 1″ wide specimen from the package. The specimen is then inserted into the jaws of a test stand such as an Inston, with one half of the material in the top jaw and the lower half of the material in the bottom jaw. The test stand then automatically moves the opposing jaws apart, causing the seal between them to peel apart at a constant rate of speed. A load cell measures the force required to fully separate the seal.

General introduction

T-Peel Resistance Test Fixture for Adhesives is based on ASTM D1876 standard, used to measure the adhesion strength of adhesive maeterial. ASTM D1876 peel strength test method is commonly used to measure the strength of adhesive bonds between two sealed materials, especially the closure seal of a sterile barrier package, such as a pouch or tray. The test is conducted by first cutting a 1″ wide specimen from the package. The specimen is then inserted into the jaws of a test stand such as an Inston, with one half of the material in the top jaw and the lower half of the material in the bottom jaw. The test stand then automatically moves the opposing jaws apart, causing the seal between them to peel apart at a constant rate of speed. A load cell measures the force required to fully separate the seal.


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 attaches the load. The bond will separate at 127 mm (5 in.) per minute at this speed. The peel test records an autographic plot of load versus head movement or load versus distance peeled. Then, the peel resistance of the bond line is determined over at least 127 mm (5 inches) of length after the initial peak.

ISO 252 Conveyor belts Elements Adhesion Strength Peeling Test

ISO 252 specifies two test methods (A and B) for measuring adhesion strength between the constituent layers of conveyor belts: between top/bottom covers and carcass, and between individual plies. 

ISO 29862 Tape adhesion peeling test, Self adhesive tapes

ISO 29862 Self adhesive tapes — Determination of peel adhesion properties

ISO 29862 specifies peel adhesion force of pressure-sensitive adhesive (PSA) tapes under controlled laboratory conditions. It covers four core 180° peel test methods plus two normative annexes for low-temperature and 90° peel testing, serving as a universal quality control and material comparison benchmark for adhesive tape manufacturers, laboratories and end users worldwide.

ASTM D3330 tape peeling test, Method for Peel Adhesion of Pressure-Sensitive Tape

ASTM D3330/D3330M: Standard Test Method for Peel Adhesion of Pressure-Sensitive Tape


ASTM D3330 test methods cover the measurement of the peel adhesion of pressure-sensitive tapes.


ISO 11339 T-peel test for Adhesives

ISO 11339 Adhesives — T-peel test for flexible-to-flexible bonded assemblies.


It specifies a T‑peel test for the determination of the peel resistance of an adhesive by measuring the peeling force of a T‑shaped bonded assembly of two flexible adherends.  The ISO 11339 test method is suitable for self-adhesive tapes that are prepared under the relevant guidelines within this test standard. For a T-peel test for a flexible-to-flexible assembly, the force is applied to the unbonded ends of the specimen . The angle between the bond line and the direction of the applied force is not fixed. 

ISO 8510-2 Adhesives 180 degree peel test for flexible-bonded-to-rigid test specimen assembly

ISO 8510-2: Adhesives — Peel test for a flexible-bonded-to-rigid test specimen assembly Part 2: 180° peel.


ISO 8510-2 specifies the 180-degree peel adhesion test for evaluating the adhesive peel strength of bonded materials. This standard is essential in industries such as packaging, medical devices, electronics, and adhesives, where strong and reliable adhesion is crucial. The test provides critical insights into the performance and durability of adhesives by measuring the force required to separate a flexible adherend from a rigid adherend under controlled conditions.


Testing Procedure: 

The rigid adherend is clamped into the machine’s fixed grip.

The flexible adherend is clamped into a self-aligning grip.

The machine applies force parallel to the bonded plane, pulling the flexible adherend at a 180-degree angle.

ASTM D1876 T-Peel Resistance Test of Adhesives

ASTM D1876: Standard Test Method for Peel Resistance of Adhesives (T-Peel Test)


ASTM D1876 test method is primarily intended for determining the relative peel resistance of adhesive bonds between flexible adherends by means of a T-type specimen using a tension testing machine. The bent, unbonded ends of the test specimen shall be clamped in the test grips of the tension testing machine and a load of a constant head speed shall be applied. An autographic recording of the load versus the head movement or load versus distance peeled shall be made. The peel resistance over a specified length of the bond line after the initial peak shall be determined.
