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.

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:
