Block size: 60mm | round

Block material thickness: 10mm

Standard hardness values: 40 / 70 /  100 / 150 / 200 / 250 / 300 / 350 / 400 / 450 / 500 / 550 / 600 / 650 / 700 / 750 / 800

Calibration details: INNOVATEST Macro Vickers hardness calibration blocks are calibrated & DUAL-certified by UPI Laboratories, accredited by the Dutch National Board of Accreditation and are traceable to National/International standards according to ISO 6507/3 & ASTM-E92 A4.

Calibration environment:  (23 ± 2) °C, < 70 %rh

Validity: This reference block is valid for the scale for which it was calibrated. It is recommended to replace reference hardness test blocks every 5 years. Blocks manufactured of Al-alloys and Cu-alloy, should be replaced within 2 to 3 years.

Uncertainty: The expanded uncertainty is based on a standard uncertainty multiplied by a factor (k=2), providing  a confidence level of approximately 95%. The evaluation of the uncertainty is carried out in accordance to International requirements.

Traceability: All measurements involved will be traceable to international applicable standards.
