《产品几何技术规范（GPS）一般概念第2部分：基本原则、规范、操作符和不确定度》（ISO/TS 17450-2：2002）是由ISO TC 213《尺寸和几何产品规范和验证》（Dimensional and geometric product specifications and verification）最近发布的。该文件定义了许多新概念，为新一代几何产品规范标准提供了基础，并有可能彻底改变我们对规范和验证的看法。它通过将规范定义为有序的操作集来增强规范语言，这是一种比简单的公差带概念更丰富的语言。此外，它扩展了不确定性的概念，从与量化需求、规范和验证中的模糊性有关的通用货币。这些新概念为计量学家和计量仪器供应商带来了新的机遇和新的挑战。本文探讨了其中的一些机遇和挑战。
“Geometrical product specifications (GPS)—General Concepts—Part 2: Basic tenets, specifications, operators and uncertainties” (ISO/TS 17450-2:2002) was recently published by ISO TC 213 “Dimensional and geometrical product specifications and verification”. This document defines a number of new concepts that provide the underpinnings for a new generation of standards for geometrical product specifications and have the potential of revolutionizing how we think about specification and verification. It enhances the specification language by defining specifications as ordered sets of operations, a much richer language than the simplistic notion of tolerance zones. Additionally, it expands the concept of uncertainty from being something measurement related to being the universal currency for quantifying ambiguity in requirements, specifications and verifications. These new concepts present new opportunities and new challenges both to metrologists and to providers of metrology instrumentation. This paper explores some of these opportunities and challenges.
