Specimen Notcher for Plastic Materials

Easily and precisely notch test specimens for izod and charpy testing of plastic materials to ASTM and ISO specifications.

• Conforms to ASTM D256 & D6110; ISO 179 & 180
• Variable cutter speed, Variable speed table feed rate.
• Air cooled notching area
• Replaceable diamond- tipped cutter

The Tinius Olsen Model 899 Impact Specimen Notcher for Plastics is designed to machine a notch in a plastic specimen in accordance with ISO 179, ISO 180, ASTM D256 and ASTM 6110.

Prior to performing tests, the specimens must be notched in order to create a stress riser and to predict the point of fracture. The Tinius Olsen Model 899 Impact Specimen Notcher for Plastics can accurately machine up to 28 3.2 mm (1/8") thick specimens at one time.

The Model 899 Specimen Notcher features an air cooling system that directs air flow at the cutting area to reduce the risk of thermal.degradation of the specimens. A clear safety cover over the cutting area protects the operator, while doubling as an attachment for a vacuum system (not supplied) to remove chips from the cutting area.

Routine operation of the Model 899 Impact Specimen Notcher for Plastics is automated and requires a minimum of operator super- vision. After samples are loaded, the operator initiates the automatic notching cycle by simply pressing a button.

After the notching process is completed, the notch depth can be verified by using the Model 799 Notch Depth Verification Device.
