How do you measure Elongation of adhesive tape?

 

Elongation

This is measured at the same time of measuring tensile strength. Percentage of elongation, when adhesive tape is to be pulled from both ends until break, is measured.

If the value is 50%, it means 100mm tape is able to elongate to 150mm.
