1 Scope

The order applies to standard torque wrench initial verification, use and subsequent verification check.

2 Terms and Definitions

2.1 standard torque wrench standardtorquewrench It refers to the high level of accuracy and torque wrench to the torque wrench Calibrator value transfer. 2.2 Maximum arm length maximumarmlength Standard torque wrench with square Falcon center point of application of the maximum distance, usually 90% of the standard torque wrench's length about. 2.3 Minimum arm length minimumarmlength The minimum standard torque wrench from the force application point and the center of the square Falcon, typically 60% of the standard torque wrench's length about.

3 Overview

Standard torque wrench is a high accuracy in torque measurement means different arm positions Shi twist, the standard torque Wrench normally applied by the torque arm, indicating instrument and sensor components, mainly used for torque wrench Calibrator for examination.
