本技术报告规定了规定和测试三坐标测量机（CMM）性能的要求和方法，该三坐标测量机有三个相互垂直的线性轴，且最多有一个旋转轴相对于这些线性轴任意定位。除了澄清CMMs的性能评估外，本技术报告还试图通过统一术语、一般机器分类和环境影响处理，促进机器之间的性能比较。这是B89的重新设计和更新。4.1-1997. 它的创建是为了协调B89。4.1通过将整个10360.2文件并入ISO 10360.2标准，并添加可在整个技术报告文本框中找到的附加要求。

This Technical Report establishes requirements and methods for specifying and testing the performance of coordinate measuring machines (CMMs) having three linear axes perpendicular to each other and up to one rotary axis positioned arbitrarily with respect to these linear axes. In addition to clarifying the performance evaluation of CMMs, this Technical Report seeks to facilitate performance comparisons among machines by unifying terminology, general machine classification, and the treatment of environmental effects. This is a redesignation and update of B89.4.1-1997. It was created to harmonize the B89.4.1 standard with ISO 10360.2 by incorporating the entire 10360.2 document into it and adding additional requirements that can be found in text boxes throughout the technical report.
