FABRIC STIFFNESS TESTERS ASTM

The Fabric Stiffness Tester is a simple to use, rugged instrument based on a design described in internationally recognized test standards such as ASTM D1388. Employing the principle of cantilever bending, a rectangular specimen is supported on a smooth low-fiction horizontal platform with a 41.5” (0.724 rad) or 45” (0.785 rad) adjustable bend angle indicator below the plane of the platform surface. A weighted slide is placed over the specimen and is advanced at a constant rate.
