SATRA STD 155 Heel impact tester

STD 155 Heel impact tester image

This device is used for determining the resistance of heels to sudden impact loads in wear caused by abnormal stresses.

STD 155 has been extensively used for heel development and quality control.

The heel under test is held rigidly at the seat in a fusible alloy clamp (supplies available from SATRA Ref: 303976) in a position which allows the falling pendulum/striker to strike the heel in a forward direction approximately perpendicular to the stem and 6mm from the tip of the heel.

The complete clamp is fully adjustable to accommodate any normal heel design. The normal method of testing is to subject the heel stem to successive impacts starting at 0.5 joules and in increments to a maximum of 19 joules.
