Test Method: SATRA TM10

Longitudinal stiffness - three point bending test

October 1996

SCOPE

This method is intended to determine the stiffness and the modulus of elasticity of a material. The method is mainly applicable to soling and insole materials used in footwear construction but can be used with any type of semi-rigid sheet material.

PRINCIPLE

A rectangular test specimen is supported across its width at two points. The force, applied midway between the points, required to bend the test specimen by a known amount, is measured and its stiffness modulus and stiffness calculated.

REFERENCES

This Test Method does not reference any additional Standards or Test Methods.
