摘要：

The Small Punch (SP) test technique is used for the evaluation of actual tensile, fracture and creep characteristics of materials exposed for a long period in operating plant components in order to provide data needed for plant life and integrity assessment. In the present paper the results of SP tests in the temperature range from -193 degrees C to +20 degrees C, carried out in two laboratories on low alloy steel of type 14MoV6-3 in as received state and after long term operation at 540 degrees C were compared. SP transition temperatures T-SP determined from the temperature dependences of the fracture energy were correlated with the FATT temperatures obtained using standardized Charpy V notch test specimens.
