How to Calculate UTS
This gives a value in N/mm² or MPa. During a tensile test, the material is pulled until it breaks. The highest recorded force, divided by the original cross-sectional area, gives the UTS. This value is the peak on a stress-strain curve.

ASTM D4541-09e1
This test method uses a class of apparatus known as portable pull-off adhesion testers. They are capable of applying a concentric load and counter load to a single surface so that coatings can be tested even though only one side is accessible.

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.
