HR15N Carbide Rockwell Reference Blocks 25mm x 25mm x 6mm

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 ± 1 points. (For example if you select 95 HR15N, we will supply anything from 94 to 96 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 96 HR15N  ≤ 0.3 HR15N
• Uncertainty of Measurement : 40 to 80 HR15N is 0.39 HR15N, 80 to 96 HR15N is 0.18 HR15N.
