ISO/TS 15530-4:2008规定了（基于仿真的）不确定度评估软件（UES）应用于坐标测量机（CMM）测量的要求（针对制造商和用户），并给出了用于评估特定任务测量不确定度的仿真技术的信息性描述。 ISO/TS 15530-4:2008描述了此类模拟软件的测试方法，以及各种测试方法的优缺点。 ISO/TS 15530-4:2008还描述了通过模拟CMMs上执行的特定测量任务来评估任务特定不确定度测定的各种测试程序，考虑到测量设备、环境、测量策略和对象。 本文件描述了一般程序，但不限制技术实现的可能性。包括验证和评估模拟包的指南。

ISO/TS 15530-4:2008 specifies requirements (for the manufacturer and the user) for the application of (simulation-based) uncertainty evaluating software (UES) to measurements made with coordinate measuring machines (CMMs), and gives informative descriptions of simulation techniques used for evaluating task-specific measurement uncertainty. ISO/TS 15530-4:2008 describes methods of testing such simulation software, along with advantages and disadvantages of various testing methods. ISO/TS 15530-4:2008 also describes various testing procedures for the evaluation of task specific uncertainty determination by simulation for specific measurement tasks carried out on CMMs, taking into account the measuring device, the environment, the measurement strategy and the object. This document describes the general procedures without restricting the possibilities of the technical realization. Guidelines for verification and evaluation of the simulation package are included.
