Bending Stiffness Tester TABER® STIFFNESS TESTER 362 T

Description

The Original TABER® Stiffness Tester 362 T remains the standard for stiffness testing and is referenced in the specifications of many standards organizations. Pioneered by Taber in 1937, the Stiffness Tester has been continuously enhanced to meet modern testing requirements and specifications. It is used for tests on flexible materials such as thin plastic plates, paperboard, paper, metal foils, felt, leather etc.

Precise determination of the bending stiffness of a wide variety of materials

A bi-directional pendulum weighing system provides an accurate and responsive method for measuring small load increments to evaluate the resistance to bending.

Force is applied to the lower end of the specimen by rollers attached to the driving disc. Located directly behind the pendulum, the driving disc pushes the rollers at a constant rate against the specimen which deflects it from its vertical position. The pendulum applies increasing torque to the specimen as it deflects further from the vertical. The test point reading occurs when the pendulum mark aligns with the appropriate driving disc mark (7.5° or 15°) which points to the stiffness reading on the fixed annular disc.

The TABER® STIFFNESS TESTER 362 T (150-T) can test paper and paperboard along with other sheet materials or wire.

Recognized in international test standards

The TABER® STIFFNESS TESTER 362 T (150-T) is used to determine the bending moment required to deflect the free end of a vertically clamped specimen 15° to the left and to the right when a load is applied at a constant bending length. Readings taken in the two directions are averaged to give the stiffness of the test piece. The resistance to bending is calculated from the bending moment.

Tappi T489 or ISO 2493 is intended for most paper or paperboard. Tappi T566 is intended for papers of low grammage or are highly flexible and exhibit bending stiffness in the range of 0 to 10 Taber Stiffness Units.

Test a wide range of materials

Nine (9) distinct testing ranges permit testing materials that are extremely lightweight and flexible to materials that are very rigid. Each range has a specific roller position and pendulum load which is adjustable through supplemental weights. The TABER® STIFFNESS TESTER 362 T (150-T) can test materials including paper, paperboard, plastics, metals, nonwovens, textiles, rubber, felt and many others. Wire and cable stiffness characteristics may also be evaluated.
