This Standard is a geometrical product specification (GPS) standard and is to be regarded a

For more detailed information of the relation of this Standard to other standards and the GPS matrix model see annex B. Coordi
20、nate measurement technology is widely used in industrial metrology to as- sess features of a workpiece. A common requirement is to fit an associated feature to a data set consisting of coordinate measurements of a real feature. This fitting is carried out by software. Software for calculating an ass
21、ociated feature provides values of parameters of the associated feature that are descriptive of the size, shape, location and orienta- tion of the feature. These parameters are useful for the purpose of carrying out cal- culations involving the feature, often in conjunction with other associated fea
22、tures and other information, and in determining the extent to which a workpiece satisfies dimensional and positional specifications. The reliability of information about features that is determined from associated features is influenced by the quality of the software for computing these features. Th
23、e tests defined in this Standard are concerned with assessing the correctness of the parameters of computed associated features as measured by a coordinate measuring machine (CMM) or other coordinate measuring system. Although differ- ent criteria may be used to compute associated features (for exam
24、ple, by minimizing the Euclidean or Chebyshev norm of residuals), this test is applicable for software designed for unconstrained Gaussian (least-squares) features. In the case of reverification tests of CMMs, the software test of this Standard usually does not provide new or different information i
