If a measurement falls within the range where uncertainty overlaps the tolerance limit, a clear decision of conformity or nonconformity cannot be made without further analysis or customer-supplier agreement. Key Terminology and Zones
在供应商/客户关系中，ISO 14253-1建立了完整的争议处理机制。配合ISO 14253-3标准提供的指南，双方可以就争议的测量不确定度声明达成协议，有效避免成本和时间的浪费。处理不确定度预算过程中的争议时，应按以下顺序评估和达成一致：测量任务、不确定度模型、不确定度贡献因子列表、可能的修正、不确定度贡献因子大小、因子之间的相关性以及k值/置信度水平。
值得注意的是，ISO 14253-1的新版本ISO/FDIS 14253-1已进入最终国际标准草案（FDIS）阶段，意味着新一轮的修订工作正在稳步推进。虽然2025年版尚未正式颁布，但技术委员会仍在不断优化标准的适用性和可操作性，相关的研究与应用已经全面展开。 international standard iso 14253 1pdf exclusive
