Test Method: SATRA TM59

Longitudinal stiffness of insole backparts

September 2000

SCOPE

This test method is intended to determine the stiffness in the longitudinal direction of insole backparts used in footwear. The method is applicable to all insole backparts for all types of footwear, including plastic backparts with or without a shank, and fibreboard backparts reinforced with a shank.

PRINCIPLE

The test specimen is clamped at its rear end, in a moulded resin block, and bent as a cantilever beam by adding weights to the free end. The extent of the bending is measured and used to calculate the flexural rigidity of the backpart.
