Torsional Stiffness Apparatus 108

Measure the relative stiffness of leather and other flexible materials.

ASTM D2821

Torsional Stiffness Apparatus 108

Stiffness Tester Model 108 is based on the torsion apparatus described in test method ASTM D2821 Standard Test Method for Measuring the Relative Stiffness of Leather by Means of a Torsional Wire Apparatus. It is used to measure the flexibility and stiffness of a leather or other bendable specimen and has been shown to be a reliable method of evaluating the relative stiffness of leather used in gloves.

Simple to use, rugged design provides repeatable test results.

Mounted to a rigid stand, the instrument consists of a torsion head, fixed torsional wire and specimen clamping system. A specimen is affixed to a weighted clamp secured at the bottom of a torsion wire. A torsion head equipped with a dial protractor is turned in a plane normal to the torsion wire until the specimen has been twisted 90°. Torsion values are obtained by measuring the applied angular twist required to reorient the sample 90° or some other specified setting.
