What is fastening torque
Fastening torque refers to the rotational force applied to tighten a fastener, typically measured in Newton-metres (N·m) or pound-force inches (lbf·in). The correct torque value ensures adequate clamping without overstressing components.

Interpreting test results
Peel strength is typically reported in newtons per metre (N/m) or per 25 mm of bond width (N/25mm), depending on the industry standard. From the force-displacement graph, the following characteristics are analysed:
