| 11. | Currently some watch companies are improving the crystal watch glass by testing the strength using the Vickers hardness test.
|
| 12. | The Janka Hardness test results tabulated below were done in accordance with ASTM D 1037-12 testing methods.
|
| 13. | A "'nanoindenter "'is the main component for indentation hardness tests used in nanoindentation.
|
| 14. | The everyday consumer is now being made aware of crystal strength in their watches due to the Vickers hardness test.
|
| 15. | However, it has been experimentally determined through " strainless hardness tests " that the effect is minimal with smaller indentations.
|
| 16. | The "'Janka hardness test "'measures the resistance of a sample of wood to denting and wear.
|
| 17. | This is a more fundamental measurement of hardness than other hardness tests which are based on the surface area of an indentation.
|
| 18. | The "'Meyer hardness test "'is a rarely used hardness test based upon projected area of an impression.
|
| 19. | The "'Meyer hardness test "'is a rarely used hardness test based upon projected area of an impression.
|
| 20. | The "'Leeb rebound hardness test "'is one of the four most used methods for testing metal hardness.
