Taber Stiffness Testers

The Taber Stiffness Tester utilizes a two directional pendulum-type weighing system to evaluate material stiffness, flexural strength, resiliency and elasticity properties. Predetermined sample length, deflection angle and rate of loading provide accurate and reproducible test results. Force is applied to the lower end of the specimen by a pair of rollers attached to the driving disc.

The resulting torque tilts the pendulum from its vertical position and a Taber Stiffness Unit reading (gcm) is taken when the pendulum mark aligns with the appropriate driving disc mark (7-1/2” or 15°). Nine distinct setups permit the testing of very delicate to extremely rigid materials up to 5.5 mm (0.219 inches) thick.

Based on the original Taber Stiffness Tester, Model 150-B requires the user to record stiffness testing data, average the readings and multiply results by a scaling factor.

The user manually operates the pendulum deflection by a lever control switch. A dynamic brake holds the pendulum in position enabling the operator to capture the unit scale reading. Mounted on tripod legs, this instrument is lightweight for easy portability.

• Size 9” x 11” x 16”
  
• Weight Normal, 15 lbs. Shipping Weight, 26 lbs.

The High Sensitivity Attachment (also referred to as Sensitivity Range Attachment) is used to test the stiffness of extremely lightweight materials.

A 1-1/2” x 1-1/2” specimen is mounted between a set of pin holders, which replace the rollers.
