Taber oscillation and wear instrument
Application
The Taber Oscillation and Wear Instrument is designed to evaluate the abrasion resistance and transparency of various materials and coatings. It is widely used for:
Transparent materials, including glass and optical lenses
Organic coatings on plastics, metals, and other substrates
Comparison of reference lenses via the Bayer wear test
Simulating wear and tear under daily-use conditions using solid or liquid abrasive media
This instrument allows testing with a range of abrasives, such as quartz sand, alumina, emery, or glass beads. Liquid abrasive slurries can also be used for combined wear and corrosion tests. Adjustable oscillation stroke and speed provide flexibility for different test scenarios.
Standards
ASTM F735 – Standard Test Method for Abrasion Resistance of Transparent Plastics
ARCA AR-C STP 5.2.5 – Bayer Wear Test
