This standard specifies the test methods for longitudinal flexural stiffness of steel shanks of leather shoes.
This standard is applicable to the measurement of longitudinal flexural stiffness of steel shanks, unishanks and shankboards of leather shoes.
2 Principle
The shank is clamped at its heel end and bent as a cantilever beam by masses added to its forward end. The amount of bending is measured and used to calculate the flexural rigidity of the shank (unishank and shankboard).
