Labeling
The following information is put onto the side surface of the hardness test block:
- Manufacturer's logo (Centre "МЕТ");
- Verification month;
- Test block serial number assigned by the National Metrological Institute of Russia, which performed the calibration;
- Hardness value with an indication of the hardness scale.
The state mark of verification belonging to VNIIFTRI is put onto the working area (right lower angle).
Advantages
- Minimum dispersion of hardness readings along the surface;
- Long-term stability;
- Manufacturing according to individual orders (on all hardness scales and ranges);
- Delivery by piece and in sets.

Calibration, verification, certification
First and second category standard hardness measures are hardness measuring instruments subject to mandatory verification. Initial and periodic verification of measures is carried out by state metrological service bodies accredited for the right to verify hardness measuring instruments. The verification interval is 2 years.
In accordance with the current state verification schemes, first category measures are calibrated only on state hardness standards of Russia (the custodian of hardness standards is FSUE "VNIIFTRI"). Working hardness measuring instruments (stationary, portable and handheld hardness testers) are verified according to second category measures.
