The Stiffness Tester (Taber Type) is designed to evaluate the stiffness and resilience of paper, plastics, cardboard, light metallic sheets, foil, and other flexible materials with comparatively high bending resistance.

In this test, a 38 mm wide specimen is clamped between a vice mounted on a balanced pendulum supported by antifriction bearings and a lower clamp fixed on a rotating disc. The specimen is bent to an angle of 15° at a constant speed. When the effective load length reaches 50 mm, the bending moment required to deflect the specimen is measured in g·cm units, and the stiffness value is determined. The disc rotates both clockwise and counterclockwise, allowing stiffness measurement in both directions.

Measuring Range: 0–5000 Stiffness Units

Optional Accessory: Triple shear cutter for accurate sample preparation

Dimensions: 10” × 11” × 16”

Ideal for paper mills, packaging industries, and material testing laboratories requiring precise stiffness evaluation.
