HR15N Rockwell Reference Blocks 65mm Ø x 15mm

Description

• HR15N Reference blocks are calibrated with a Standardizing Diamond Indenter.
• Major Force applied is 15kg with a pre-load of 3kg.
• All blocks are supplied with a UKAS or EURO certificate.
• Nominal values selected are supplied within ± 2 points. (For example if you select 85 HR15N, we will supply anything from 83 to 87 HR15N. We will always try our hardest to get as close to the nominal value as possible.)
• Uniformity of Hardness Calibration Guarantee for the following values:
  •  69 HR15N to 88 HR15N  ≤ 0.5 HR15N
  •  89 HR15N to 94 HR15N  ≤ 0.3 HR15N
• Uncertainty of Measurement : 40 to 80 HR15N is 0.39 HR15N, 80 to 95 HR15N is 0.18 HR15N.
