Test Method: SATRA TM2

Tensile properties of insole materials

December 2021

SCOPE

This method is intended to determine the tensile properties of insole materials using one of two procedures. The first determines the tensile strength and the second the force required to break the material, its extension at break and its modulus of elasticity. The first method is applicable to all types of semi-rigid insole material. The second method is applicable to flexible materials such as those used for sewn-in sock constructions.

PRINCIPLE

Method 1 - Tensile strength (Semi-rigid materials)

A dumb-bell shaped test specimen is gradually stretched, by a tensile testing machine, until it fails. The tensile strength of the specimen is determined. The test can be carried out with either dry and/or wet specimens as required.

Method 2 - Breaking strength, extension at break, and modulus (Flexibles)

A rectangular test specimen is gradually stretched, by a tensile testing machine, until it fails. The breaking strength, the extension at break and the modulus of elasticity at 5 % extension, of the specimen are all determined. The test is normally only carried out on dry specimens.
