This International Standard specifies frequency and methods for the verification of pendulum impacttestingmachines used for the Charpy impact test, Izod impact test, and tensile impact test describedin ISO 179-1, ISO 180, and ISO 8256, respectively. Verification of instrumented impact machines iscovered insofar as the geometrical and physical properties of instrumented machines are identical tonon instrumented machines. The force/work verification of instrumented machines is not covered inthis International Standard.This International Standard is applicable to pendulum-type impact-testing machines, of differentcapacities and/or designs, with the geometrical and physical properties defined in Clause 5.Methods are described for verification of the geometrical and physical properties of the differentparts of the test machine. The verification of some geometrical properties is difficult to perform on theassembled instrument. It is, therefore, assumed that the manufacturer is responsible for the verificationof such properties and for providing reference planes on the instrument that enable proper verificationin accordance with this International Standard.These methods are for use when the machine is being installed, has been repaired, has been moved, oris undergoing periodic checking.A pendulum impact-testing machine verified in accordance with this International Standard, andassessed as satisfactory, is considered suitable for impact testing with unnotched and notched testspecimens of different types.Annex A details design requirements for Charpy testing machines.Annex B details design requirements for Izod testing machines.Annex C details design requirements for tensile impact machines.Annex D explains how to calculate the ratio of frame mass to pendulum mass required to avoid errorsin the impact energy.Annex E explains deceleration of pendulum during impact.Annex F details design requirements for one type of gauge used to verify striker and anvil/supportalignment for Charpy testing machine.
