March 1999
SCOPE
This method is intended to determine the endurance of a material to repeated flexing. The method is applicable to most types of semi-rigid sheet material and in particular fibreboards.
PRINCIPLE
A specimen is held in tension and repeatedly flexed through 180° until failure occurs. The base 10 logarithm of the number of flexing cycles to failure is calculated to give the flexing index of the material.
