ASTM D6862 – Standard Test Method for 90 Degree Peel Resistance of Adhesives

Peel strength testing for adhesive tapes can be performed using different test procedures.

The 90 degree peel test is one of the most common since this test generally results in the lowest peeling force.

ASTM D6862 – 90 Degree Peel Test Fixture

 

Peel strength testing for adhesive tapes can be performed using different test procedures.

ASTM D6862 – The 90 degree peel test is one of the most common since this test generally results in the lowest peeling force.

*** Variations of this test include the 180 degree peel test, floating roller peel test, climbing drum peel test, and the T-peel test or trouser method. 

ASTM D6862 – This test is also specifically designed to measure the elasticity of the adhesives.

Elasticity can be an independent determiner of peel strength. Glues with strong adhesive properties could have weak performance if the cohesive strength of

the adhesive is low.

Low cohesive strength means that the glue has high elasticity and the stress of the pulling force is distributed over a wider cross-sectional area.

Adhesives with low elasticity are typically strong because they concentrate stess over a small cross-section as they are peeled at a 90 degree angle.


ASTM D6862 – 90 Degree Peel Setup

Solution

The fixture for this test is unique because of where the load cell must be mounted.

Since the stage must move without disrupting the load, the adapter wing arm must be attached behind the load cell.

This allows the fixture stage to move independently and maintain a 90 degree angle throughout the test.

Average peel strength during the middle of the test is the most common calculation result.

Adjustable angle stages are also available.
