Foreword

This standard was drafted in accordance with the rules of GB/T 1.1-2009 and GB/T 20000.2-2009 given. This standard replaces GB/T 14123-1993 "shock machine characterization", compared with the GB/T 14123-1993, the main content as follows. --- Modify the standard name from "shock machine characterization" to "mechanical impact test machine performance characteristics"; --- Modify the standard structure, the original 6 into seven chapters. Each chapter adds the content; --- Increasing the introductory phrase normative references and some reference standards, and the effectiveness of the standard was confirmed; --- To increase the content of "impact testing machines" (see Chapter 7); --- Added Appendix C, Appendix D, Annex E and Annex NA. This standard uses the translation method identical with ISO 8568.2007 "Mechanical impact test characteristics and performance." Consistency correspondence between this standard international standard documents and normative references of our document Appendix NA. This standard makes the following editorial changes. --- Supplementary Fig C.4 image omission.

This standard replaces the standards previously issued as follows. --- GB/T 14123-1993. Mechanical impact test machine performance characteristics

1 Scope

This standard specifies the mechanical impact testing machine (hereinafter referred to as impact machine) performance parameters and test methods, and gives a description of the impactor Guidelines characteristics. This standard is intended to provide a detailed account of the impact of machine characteristics for potential customers, but also gives the impact machine selection guide. This standard applies to verify and assess the relevant part of IEC 60068 specified operating environment impact conditions typical effects which impact Machine, also for the diagnosis of the impact test machine. Impact test purpose is to find the weak links in the mechanical and (or) to find the prescriptive You can decline. This standard can also be used to determine the structure of a solid test sample or as a method of quality control. This standard does not apply to simulate earthquakes, sonic booms, explosion and implosion, rupture tests, as well as metal processing, forming and other types of punch Hit device. The standard for a variety of techniques to produce the desired impact exercise were discussed. Whether single or composite impulse transients Application of these technologies are able to achieve. By using a predetermined shock response spectrum test control enables the transient impact processes simulation. Note 1. Appendix A describes the shock pulse forming apparatus. Appendix B provides shock response spectrum method is applied. Appendix C discusses the possible vibration generator Evaluation method generates the impulse. Appendix D and Appendix E dealt with the detection of certain characteristics in shock machine test method (or program). Note 2. Characteristics of vibration test equipment in ISO 5344, ISO 6070 and ISO 8626 are to be specified.
