Before being launched on the market, each batch of superabrasive is carefully submitted to a battery of tests in the laboratory which is certified ISO 9002.
The following physical properties are carefully tested and analyzed:
- size distribution average
- size standard deviation
- shape factor
- shape standard deviation
- eccentricity (computed optical analysis)
- strength (Toughness Index)
- microshipping resistance
- wear resistance
- strength after heat treatment (Thermal Toughness Index)
- microchipping resistance after heat treatment
- thermal stability (based on the weight loss and the TTI/TI ratio)
For each batch, all test results of the above characteristics are computed and, through a mathematical model, a Performance Index is defined.
