标准范围

ISO 6789-2:20 17规定了手动扭矩工具的校准方法，并描述了校准测量不确定度的计算方法。ISO 6789-2:20 17规定了扭矩测量装置校准的最低要求，其中相对测量不确定度区间W’md尚未由可追溯的校准证书提供。ISO 6789适用于扭矩测量装置的逐步（静态）和连续（准静态）校准，扭矩测量装置的扭矩通过测量可变形体的弹性形式变化或与扭矩成比例的测量变量来定义。ISO 6789-2:20 17适用于手动扭矩工具，分为指示扭矩工具（I型）和设定扭矩工具（II型）。注:本文件涵盖的手动扭矩工具是ISO 1703:2005中通过参考号6 1 00 11 0、6 1 00 11 1和6 1 00 12 0、6 1 00 12 1和6 1 00 14 0、6 1 00 15 0标识的手动扭矩工具。ISO 1703目前正在修订中。在下一个版本中，扭矩工具将被移到自己的条款中，随着这一变化，参考号也将发生变化，并将添加额外的参考号。

ISO 6789-2:2017 specifies the method for the calibration of hand torque tools and describes the method of calculation of measurement uncertainties for the calibration.ISO 6789-2:2017 specifies the minimum requirements for the calibration of the torque measurement device where the relative measurement uncertainty interval, W′_md, is not already provided by a traceable calibration certificate.ISO 6789 is applicable for the step by step (static) and continuous (quasi-static) calibration of torque measurement devices, the torque of which is defined by measuring of the elastic form change of a deformable body or a measured variable which is in proportion to the torque.ISO 6789-2:2017 applies to hand torque tools which are classified as indicating torque tools (Type I) and setting torque tools (Type II).NOTE Hand torque tools covered by this document are the ones identified in ISO 1703:2005 by reference numbers 6 1 00 11 0, 6 1 00 11 1 and 6 1 00 12 0, 6 1 00 12 1 and 6 1 00 14 0, 6 1 00 15 0. ISO 1703 is currently under revision. In the next edition, torque tools will be moved to an own clause, and with this change the reference numbers will also change and additional reference numbers will be added.
