3.1 When using this standard, reference should be made to the relevant provisions of GB.T17421.1. In particular, the installation before inspection, the high torque of the spindle and other components, the inspection method and the accuracy of the inspection process. 3.7 Adjustment according to the provisions of 3.1 in GB 17421.1-1998 The installation should be level, and the reading of the spirit level in the longitudinal and transverse directions should not exceed 00
3.3 Before inspection - the variable assembly and disassembly tools and inspection are convenient, and the actual inspection order should be arranged according to the requirements of the thermal inspection items. 3.4 When the measured length is different from the length specified in this standard, the tolerance should be sieved according to the measurable length according to the current provisions of JP/T17421.1-1998 2.3.1.1. When the conversion is less than 0005 mm, it is still calculated as 005 mm. 3.5 When testing the working sugar content, the test piece should be inspected after fine grinding. 3.6 According to the agreement between the user and the manufacturer, the inspection items can be increased or decreased: approved by the State Administration of Industry and Commerce on May 20, 1999
