24、ance, radius, angle, form, orientation, location, run-out and datums in the general GPS matrix.The ISO/GPS masterplan given in ISO/TR 14638 gives an overview of the ISO/GPS system of which this document is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this document and the defa

25、ult decision rules given in ISO 14253-1 apply to specifications made in accordance with this document, unless otherwise indicated.For more detailed information on the relation of this part of ISO 15530 to other standards and the GPS matrix model, see Annex C.It is the purpose of the ISO 15530 series

26、 to provide terminology, techniques and guidelines for estimating task-specific measurement uncertainty when using coordinate measuring machines (CMMs). These techniques allow for the evaluation of sources of uncertainty that affect a stated measurement, including the influence of the coordinate mea

27、suring system, the sampling strategy, environmental effects, operator variability and any other factors affecting the actual measurement result.CMMs are considered to be complex GPS measuring equipment, and the estimation of the uncertainty of CMM measurements often involves more advanced techniques

28、 than those described in ISO 14253-2. The techniques presented in the ISO 15530 series are compliant with both ISO 14253-2 and ISO/IEC Guide 98-3 (GUM). The techniques are developed specifically for CMMs but could be applied to other GPS measuring equipment.CMMs are specified by acceptance tests in

29、the ISO 10360 series, which typically involve their ability to measure calibrated lengths (e.g. volumetric tests using calibrated gauge blocks or step gauges) and form (e.g. probing tests using a calibrated sphere). It is recognized that although these test results may be used to determine an uncert

30、ainty for the specific types of length and form measurements involved in these procedures, without further analysis or testing, these results are insufficient to determine the task-specific measurement uncertainty of most workpiece measurements.The goal of determining the measurement uncertainty can

31、 be achieved through many different techniques; however, all methods must be consistent with ISO/IEC Guide 98-3, which yields a combined standard uncertainty. The expanded uncertainty is connected to the combined standard uncertainty via the coverage factor, which is selected to produce the desired

32、level of confidence. The default value for the coverage factor is two, i.e. k = 2, which yields a level of confidence of approximately 95 % if the uncertainty is associated with a Gaussian distribution. It is the purpose of this document to provide guidance on recognized techniques for the estimatio

The influence of the individual metrological characteristics on the uncertainty of measurement is dependent on the measurement process.
