Adhesive Peel Impact Test Method

Test the High Performance and Structural Integrity of the Adhesive Bonds Under Real Life Conditions

How to Perform a Adhesive Peel Impact Test Method

An adhesive peel impact test measures the resistance of of high-strength structural adhesives to cleavage fracture at defined velocity and user-defined temperatures. This test method is specified by the ISO 11343 standard. 

The specific setup for the adhesive peel impact test consists of a wedge with a defined shape and mass, being driven at a defined velocity into an adhesive bond securing two metallic surfaces. The test causes the bond to fracture and the adherents to peel apart. The adherents are made from aluminum or steel, which are the most used substrates most commonly in the automotive industry.

The adhesive peel impact test provides the data to calculate the dynamic resistance to cleavage, which is defined as the force per unit of width necessary to bring an adhesive joint to failure. This vital information can help manufacturers involved in the research and development of new adhesives. When a suitable product has been developed, both manufacturer and end-user can implement a quality control program utilizing baseline data from the impact performance tests to provide ongoing process validation and quality control.

Wedge Peel Impact Test

The specific setup for the Adhesive Peel Impact Test Method involves:

Instron 9450 Drop Weight impact testing machine equipped with thermostatic chamber and impact testing machine parts dedicated to ISO 11343, including:
  • A dedicated striker;
  • A vice equipped with a strain-gauge sensor (15 kN), a clamp for adhesive bond specimen;
  • Both symmetric and asymmetric wedges with shape according ISO requirements;
  • A Data Acquisition System with a strain-gauge channel


The Data Acquisition System with a sampling frequency up to 4MHz and Bluehill Impact software are critical for proper data collection and automatic results analysis.

The thermostatic chamber enables the user to test at low and high temperatures and experiment with different material compositions, cure conditions and climatic temperatures to optimize product performance and comply with government regulations. Real life testing scenarios can be simulated within the range from -40°C to +80°C, very typical climatic conditions for the automotive industry.
