本标准适用于关节臂坐标测量机（AACMMs）的性能评估。虽然可以对任意数量的旋转接头进行评估，但该标准侧重于目前市面上更常见的配置，且仅限于七个接头。该标准涉及纯手动机器，因此当前文档中没有涉及机动轴。虽然这类测量机的应用继续增长，但目前只考虑接触式探头，而特别排除光学非接触式探头。本标准规定了AACMMs性能规定和测试的要求和方法。除了澄清AACMMs的性能评估外，本标准还通过统一术语、一般机器分类、环境影响处理和数据分析，促进机器之间的性能比较。 本标准试图定义最简单的测试方法，能够为大多数AACMM产生足够的结果，并不打算取代可能适用于特殊应用的更完整的测试。

The scope of this Standard pertains to the performance evaluation of Articulated Arm Coordinate Measuring Machines (AACMMs). While any number of rotational joints can be evaluated, the Standard focuses on the more common configurations commercially available today and is limited to seven joints. The Standard addresses purely manual machines, so no motorized axes are addressed in the current document. While the application of this class of measuring machine continues to grow, at this point in time only contact probes are considered and optical noncontact probes are specifically excluded. This Standard establishes requirements and methods for specifying and testing the performance of AACMMs. In addition to clarifying the performance evaluation of AACMMs, this Standard seeks to facilitate performance comparisons among machines by unifying terminology, general machine classification, the treatment of environmental effects, and data analysis. This Standard attempts to define the simplest testing methods capable of yielding adequate results for most AACMMs and it is not intended to replace more complete tests that may be suitable for special applications.
