标准摘要
[中文适用范围]： ISO 17123 的这一部分规定了在确定和评估用于建筑和测量测量的光电测距仪（EDM 仪器）及其辅助设备的精度（可重复性）时要采用的现场程序。 ISO 17123 的这一部分仅适用于反射镜型 EDM 仪器，并非旨在确定无棱镜型 EDM 类型的精度。 这些测试主要是为了现场验证特定仪器对于当前任务的适用性，并满足其他标准的要求。 它们并不建议作为本质上更全面的验收测试或性能评估。 ISO 17123 的这一部分可以被视为评估测量（更具体地说是被测量）不确定度过程的第一步。 测量结果的不确定性取决于许多参数。 因此，我们在测试中区分不同的准确性测量和目标，例如重复性、再现性（例如日间重复性），当然还有对所有可能的误差源的全面评估，如 ISO/IEC 指南 98-3 和 ISO 17123 所规定-1。 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，并且经过专门设计，以最大限度地减少大气影响。 [外文原描述]： This part of ISO 17123 specifies field procedures to be adopted when determining and evaluating the precision (repeatability) of electro-optical distance meters (EDM instruments) and their ancillary equipment when used in building and surveying measurements. This part of ISO 17123 is applicable to reflector-type EDM instruments only and is not designed to determine the precision of non-prism EDM types. Primarily, these tests are intended to be field verifications of the suitability of a particular instrument for the immediate task at hand and to satisfy the requirements of other standards. They are not proposed as tests for acceptance or performance evaluations that are more comprehensive in nature. This part of ISO 17123 can be thought of as one of the first steps in the process of evaluating the uncertainty of a measurement (more specifically a measurand). The uncertainty of a result of a measurement is dependent on a number of parameters. Therefore we differentiate between different measures of accuracy and objectives in testing, like repeatability, reproducibility (e.g. between day repeatability), and of course a thorough assessment of all possible error sources, as prescribed by ISO/IEC Guide 98-3 and by ISO 17123-1. These field procedures have been developed specifically for in situ applications without the need for special ancillary equipment and are purposefully designed to minimize atmospheric influences.
