Scratch/Shear Tester

Introduction:

The Taber scratch/hardness testers for plastic and the textile scratch test is suitable for the scratch-resistant test of the decorative wood-based panels, with the rotation of the specimen under a certain load of the diamond needle, the test piece surface finishing layer scratch ability.

 Application:

Scratch tester used for a variety of automotive interior materials, such as plastics, rubber, leather, fabric, coating materials, coating materials and other non-composite materials such as scratch resistance detection.

Standards:

ASTM C217, L-T-751, EN 438, EN 13310, ISO 4586-2, and TERRAZZO 90322-9E-1

Operation process:

Before loading For the sample, you need to adjust the Weighing bar to the appropriate height firstly according to the sample thickness. The precision cutting tool is installed on the Weighing bar and placed on the sample. After the start of the instrument, the turntable was rotated at a constant speed to ensure accurate measurement results. By changing the load on the cutting tool, you can evaluate the shear-resistant or scratch-resistant performance of the material.

The instrument's Weighing pole design allows it to level with the sample and turntable and can be raised or lowered according to the actual needs. In addition, the Weighing pole can also be lifted in the air to facilitate the operator to remove the sample. By changing the position of the sliding balancing weight, the total load on the sample can be adjusted in the range of 0-1000 g. Cutting tools can be chosen using tungsten carbide tools or a circle conical diamond head. Visually judging the test results with the randomly-equipped 10 times magnifier, the user can also use a high-precision optical microscope to observe.
