3.3 Before inspection, the actual inspection sequence can generally be arranged according to the requirements of installation and disassembly tools, inspection convenience, and thermal inspection items. 3.4 When the measured length is different from the length specified in this standard, the allowance should be converted according to the measurable length according to the provisions of 2.3.1.1 of GB/T17421.1-1998. When the conversion result is less than 0.001mm, it is still calculated as 0.001mm. 3.5 During the working accuracy inspection, the test piece should be inspected after finishing. 3.6 According to the agreement between the user and the manufacturer, the inspection items can be increased or decreased.
