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.

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

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.

The test continues until at least 125 mm of the bonded length has separated.

The peel force is recorded over 100 mm, excluding the first 25 mm.

The failure mode (adhesive, cohesive, or adherend failure) is noted
