Introduction

The preparation of samples for mechanical properties testing involves many standards and regulations, such as testing standards, product standards, sample preparation equipment, sample preparation Process, sample processing method, etc. In order to regulate the correlation between the relevant regulations and standards for sample preparation, and to adapt to the development of sample preparation equipment and technology In accordance with the requirements of the national standardization reform, this guidance technical document was prepared. In order to increase the usefulness of this document, four appendices have been set up in this document. Appendix A describes the standard tests for commonly used mechanical properties tests. Sample, Appendix B introduces the common CNC equipment and special CNC equipment for mechanical sample processing, and Appendix C introduces the CNC equipment for some sample processing. Cases of equipment and different technological processes, Appendix D introduces the case of machining mechanical samples of medium and thick steel plates using different equipment. This document is available for each The mechanics laboratory is used as a reference when planning and designing, preparing sample processing procedures, and selecting processing equipment. Guidelines for preparing test specimens for testing mechanical properties of metallic materials
