HR30N Rockwell Reference Blocks 65mm Ø x 15mm

Description

• HR30N Reference blocks are calibrated with a Standardizing Diamond Indenter.
• Major Force applied is 30kg 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 73 HR30N, we will supply anything from 71 to 75 HR30N. 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:
  •  41 HR30N to 75 HR30N   ≤ 0.5 HR30N
  •  76 HR30N to 86 HR30N  ≤ 0.3 HR30N
• Uncertainty of Measurement : 40 to 60 HR30N is 0.55 HR30N, 80 to 87 HR30N is 0.27 HR30N.
