1 Scope This national standard specifies the method to measure the absorbed energy of metallic material in Charpy impact test (V-nick and U-nick samples). The standard does not refer to the instrumented compact test method. The instrumented compact test method is specified in GB/T 19748-2005 "Steel - Charpy V-notch Pendulum Impact Test - Instrumented Test Method". 2 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this standard. For dated reference, subsequent revisions (excluding error amendment) to, or revised edition of, any of these publications do not apply. However, parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards below. For undated references, the latest edition of the normative document is applicable to this national standard. GB/T 3808 Verification of Pendulum-type Impact Testing Machines (GB/T 3808-2002, ISO l48-2: 1998, MOD) GB/T 2975 Mechanical Test Sampling Location and Sample Preparation for Steel and Steel Products (GB/T 2975-1998 eqv ISO 377: l997) GB/T 8170 Rules for Rounding-off of Numerical Values JJG 145 Verification Regulation of Pendulum Impact Testing Machines 3 Terms and Definitions For the purposes of this national standard, the following terms and definitions apply. 3.1 Energy 3.1.1 Actual initial potential energy (potential energy) Kp It is referred to the value that directly tested with testing machine. 3.1.2 Absorbed Energy K It is referred to the energy value indicated by the pointer or other indicating devices. Note: letters "V" and "U" express the geometric shapes of the nicks. The suffixed number like 2 or 8 expresses the radius of pendulum edge, like KV2. 3.2 Sample The following terms (see Figure 1) will be used acco rding to the test position of the samples on the pedestal of testing machine: 3 2.1 Height h It is referred to the distance from the nick surface to the opposite surface hereof. 3.2.2 Width w It is referred to the length that is parallel with the axial line of the nick and perpendicular to the height direction. 3.2.3 Length l It is referred to the maximum size perpendicular to the nick direction. Note: the nick direction is the direction of the notch depth.
