标准范围

ISO 17123的本部分规定了在确定和评估测量精度时应采用的现场程序水平仪（酒精水平仪、补偿水平仪、数字水平仪）及其辅助设备（用于建筑和测量。这些测试主要是为了现场验证特定产品的适用性用于当前任务并满足其他标准要求的仪器。他们没有被提议作为更全面的验收或性能评估测试。本国际标准可被视为评估测量不确定度过程中的第一步测量（更具体地说是被测量）。测量结果的不确定度取决于许多因素。其中包括:重复性、再现性（日间重复性）和根据ISO《不确定度表示指南》的规定，对所有可能的误差源进行彻底评估在测量（口香糖）。这些现场程序是专门为现场应用而开发的，无需特殊的辅助设备设备和设备的设计旨在将大气影响降至最低。

This part of ISO 17123 specifies field procedures to be adopted when determining and evaluating the precision oflevels (spirit levels, compensator levels, digital levels) and their ancillary equipment when used in building andsurveying measurements. Primarily, these tests are intended to be field verifications of the suitability of a particularinstrument for the immediate task at hand and to satisfy the requirements of other standards. They are not proposedas tests for acceptance or performance evaluations that are more comprehensive in nature.This International Standard can be thought of as one of the first steps in the process of evaluating the uncertainty ofa measurement (more specifically a measurand). The uncertainty of a result of a measurement is dependent on anumber of factors. These include among others: repeatability, reproducibility (between day repeatability) and athorough assessment of all possible error sources, as prescribed by the ISO Guide to the expression of uncertaintyin measurement (GUM).These field procedures have been developed specifically for in situ applications without the need for special ancillaryequipment and are purposely designed to minimize atmospheric influences.
