Webb2.2. Certification of a Secondary Batch of Charpy V-notch test pieces The certified absorbed energy of a SB of Charpy V-notch reference test pieces (KV CRM) is calculated from the mean KV-value of a set of SB-samples (X SB) tested on a single pendulum. This value X SB has to be corrected for the bias of this particular pendulum. WebbThe standard Charpy-V notch specimen is 55mm long, 10mm square and has a 2mm deep notch with a tip radius of 0.25mm machined on one face. In some circumstances, sub-size Charpy specimens can be tested with thickness less than 10mm. The specimen is supported at its two ends on an anvil and struck on the opposite face to the notch by the …
