ISO 8510-2

Adhesives — Peel test for a flexible-bonded-to-rigid test specimen assembly

Test Materials

ISO 8510-2 focuses on testing adhesives used to bond flexible materials (e.g., plastic films) to rigid substrates (e.g., metal or rigid plastics). These materials are prepared as test specimens with a consistent bond area to ensure accurate results.

Test Process

The standard outlines the 180-degree peel test, where the flexible material is peeled away from the rigid substrate at a constant rate. This process involves using a tensile testing machine to apply peeling forces, ensuring precise measurement of the force needed to separate the bonded materials.

Test Result Interpretation

The results are expressed as the peel strength, typically in force per unit width (e.g., N/mm). This value reflects the adhesive bond’s durability and performance under peeling forces, providing critical data for quality assurance and product development.
