本文件的目的是记录在空载或准静态条件下运行的用于测试机床几何精度的精密测量仪器的特性。 必要时，可参考适当的国际标准。 本文件不包括用于机床运行测试的测量仪器[振动（ISO/TR 230-8）、噪音（ISO 230-5）、部件的粘滑运动等]以及用于检查机床其他特性（速度、进给、温度）的仪器。用于检查工件几何形状（尺寸、形状等）的测量仪器。 )也不在本文件的涵盖范围内。 本文件采用列表式结构，便于搜索和识别每种仪器的特征。 本文件描述了仪器和测量不确定度的来源，以便于更准确的测量程序。

The aim of this document is to document the characteristics of precision measuring instruments for testing the geometric accuracy of machine tools, operating either under no-load or under quasi-static conditions. Where necessary, reference is made to the appropriate International Standards. The measuring instruments for operational testing of machine tools [vibrations (ISO/TR 230？8), noise (ISO 230？5), stick-slip motion of components, etc.] as well as instruments for checking of other characteristics of machine tools (speeds, feeds, temperature) are not covered in this document. The measuring instruments for checking of workpiece geometry (size, form, etc.) are not covered by this document either. This document has list style construction for ease of search and identification of each instrument's characteristics. Sources of uncertainty of instruments and measurements are described in this document for more accurate measurement procedures.
