Complying with The International Cutting Test Standard for:
KITCHEN KNIVES | HUNTING, POCKET & FOLDING KNIVES | MACHINE BLADES | AGRICULTURAL BLADES | BOX CUTTERS & TOOL KNIVES | LARGE MEDICAL BLADES | WOOD CHISELS
The SAET answers the questions “How sharp is the blade?” and “How long will the sharpness last?”
- Measures the edge sharpness and durability of a large range of blades and knives for quality control, research and development, and competitor product evaluation.
- Quickly and accurately measures important cutting performance data.
- Conforms fully to the International Cutting Test Standard BS EN ISO 8442-5 : 2004.
- Semi-automatic test machine is ideal for smaller research projects and low volume quality control use.
How it works:
The cutting-edge to be tested is mounted vertically and a pack of specially developed synthetic card is lowered on to it. By moving the blade back and forth repeatedly, the blade cuts into the paper; the depth of the cut being the measurement of sharpness. The test card is loaded with 5% silica, which has a mild wearing effect on the blade edge. The measurement of cut depth at each subsequent stroke can then be plotted to produce a wear curve for each blade tested.
