25、 (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical com

26、mittee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrot

27、echnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was draft

28、ed in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

33、or the Charpy impact test, Izod impact test, and tensile impact test described in ISO 179-1, ISO 180, and ISO 8256, respectively. Verification of instrumented impact machines is covered insofar as the geometrical and physical properties of instrumented machines are identical to non instrumented mach

34、ines. The force/work verification of instrumented machines is not covered in this International Standard.This International Standard is applicable to pendulum-type impact-testing machines, of different capacities and/or designs, with the geometrical and physical properties defined in Clause 5.Method

35、s are described for verification of the geometrical and physical properties of the different parts of the test machine. The verification of some geometrical properties is difficult to perform on the assembled instrument. It is, therefore, assumed that the manufacturer is responsible for the verifica

36、tion of such properties and for providing reference planes on the instrument that enable proper verification in accordance with this International Standard.These methods are for use when the machine is being installed, has been repaired, has been moved, or is undergoing periodic checking.A pendulum

37、impact-testing machine verified in accordance with this International Standard, and assessed as satisfactory, is considered suitable for impact testing with unnotched and notched test specimens of different types.Annex A details design requirements for Charpy testing machines.Annex B details design

38、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 errors in the impact energy.Annex E explains deceleration of pendulum during impact.Annex F details desi
