LABORATORY: CNR ISPC Stone LAB
NAME OF THE INSTRUMENT
Instrumentation for surface hardness testing (Erichsen hardness tester mod.413, EQUOTIP 550 Portable Hardness Tester, OS-120PM pendulum Sclerometer, "Schmidt LIVE" Sclerometers)
GENERAL DESCRIPTION
Instrumentation includes:
- Sclerometers for testing natural stone elements, concrete, and mortar joints at different impact energies to accommodate specimens of different sizes and surface hardnesses
- Durometro portatile a rimbalzo con tecnologia Leeb
- Durometro per prove di resistenza al graffio
TECHNICAL DESCRIPTION: Sclerometers
- Original "Schmidt LIVE" N-type sclerometer with an impact energy of 2.207 Nm, equipped with graphic display, battery life of not less than 5000 impacts, and interface for data export to PC;
- Original "Schmidt LIVE" L-type sclerometer with an impact energy of 0.735 Nm, equipped with graphic display, battery life of not less than 5000 impacts, and interface for data export to PC
- OS-120PM PENDulum Sclerometer for mortars with impact energy of 0.833 Nm and a maximum diameter of impacting mass 1cm
TECHNICAL DESCRIPTION: Durometers
- Portable rebound hardness tester with Leeb technology for hardness measurements on stone materials, EQUOTIP 550 Portable Hardness Tester with "Complete Type "D" strike tool"
- Hardness tester for scratch resistance tests to determine hardness, adhesion, and scratch resistance of finishes on painted, enameled, or coated surfaces; Erichsen Universal Apparatus mod.413.
The different instruments measure the surface hardness of materials. The choice of instrument to be used depends on the physical/mechanical characteristics of the materials, sample size, and surface finish.
