Introduction

The procedure according to the rules JJF1002 "national verification procedures write rules" provisions of the preparation. This procedure separates JJG 734-2001 "force standard machine" section on force standard machine out single Alone developed a force standard machine verification. Up force within the relevant standards and JJG 734-2001 Edition machine parts Capacity compared to, in addition to editorial changes outside the main technical changes are as follows. --- Increasing the reference document (see 2); --- Modify the standard dynamometer technical requirements (see Table 5); --- Revised and increased the initial verification before the force standard machine should have the technical information (see 6.1.2); --- Modify the force standard machine accuracy class (see Table 2); --- Delete on the drop-down head concentricity requirements; --- Increasing the azimuth error indicators (see Table 2) and azimuth error test method (see 6.2.2.5); --- For the return superimposed machine, increase the return force Repeatability error and force requirements (see Table 2), Increase the return of the test method (see 6.2.2.5); --- When performed force error and azimuth error test, recommended use azimuth angle 0 °, 120 °, 240 ° azimuth position Home. If you can not achieve the above-described angular position, it allows the use of 0 °, 90 °, 180 °, 270 ° azimuthal position (see 6.2.2.5); --- Increased discrimination initial load is calculated (see equation 7); --- Modify the description and the method of calculation of load fluctuations, increase the calculation formula (see 6.2.2.7). The regulations previously issued as follows. --- JJG 734-2001 "force standard machine" --- JJG 753-91 "force standard machine" Force standard machine test procedures

3 Overview

Force standard machine (hereinafter referred to as the superposition machine) is a (or group) ratio is verification and calibration of the dynamometer Associate Really high standard dynamometer as the reference standard, to be detected force gauge (or force sensor) series, hydraulic or mechanical Applying a force standard machine force value approach. Force standard machine is mainly used for a variety of dynamometer, force sensors and load cells Test and calibration.
