真空技术.真空计.通过与参考量表直接比较对校准结果的不确定度进行的评定

[中文适用范围]： 本国际标准提供了在根据 ISO/TS 3567 进行真空规校准（通过与参考规直接比较）过程中，测量不确定度的确定和报告指南。本国际标准描述了在真空规证书中统一报告不确定度的方法。按照本国际标准指南报告的不确定度具有可传递性，即对一个结果评估的不确定度可用作另一个测量或校准（其中使用了第一个结果）的不确定度评估的一个分量。本国际标准定义了两个测量模型，足以涵盖大多数实际案例。然而，给定的模型可能无法应用于新开发的真空规。证书中最终报告的不确定度是根据输入量和影响量的不确定度评估得出的。描述了可能影响真空校准结果的主要量；然而，可能影响最终结果的所有可能量的完整列表超出了本国际标准的范围。注：预计未来的技术规范将解决特定类型真空规的校准问题。 [外文原描述]： ISO 27893:2011 gives guidelines for the determination and reporting of measurement uncertainties arising during vacuum gauge calibration by direct comparison with a reference gauge carried out in accordance with ISO/TS 3567. ISO 27893:2011 describes methods for uniform reporting of uncertainties in vacuum gauge certificates. Uncertainties reported in accordance with the guidelines given in ISO 27893:2011 are transferable in the sense that the uncertainty evaluated for one result can be used as a component in the uncertainty evaluation of another measurement or calibration in which the first result is used. ISO 27893:2011 defines two measurement models that are sufficient to cover most practical cases. However, it is possible that the models given cannot be applied to newly developed vacuum gauges.
