Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 6313-2004 "pointed micrometer". This standard is compared with GB/T 6313-2004, except for editorial modifications. In addition, the main technical changes are as follows. --- Removed the maximum allowable error value of the micrometer and its definition (see 3.3, 5.10 of.2004 edition); --- Modified the basic parameters of the measurement range (see 4.2.1, 4.2.2, 4.2 of the.2004 version); --- Increased the taper angle of the measuring end by 15° (see Table 2 in 5.4, Table 2 in Table 5.4 of.2004); --- Revised the spherical or planar diameter of the measuring end from 0.2mm to 0.3mm to 0.5mm~0.8mm (see Table 2 in 5.4). Table 2 of the.2004 edition of 5.4); --- Increase the diameter of the micrometer screw and the cylindrical part of the anvil to 6.35mm (see Table 2 in 5.4, Table 2 in Table 5.4 of.2004); --- Increased the test method for the change of the distance between the two measuring surfaces before and after locking (see 6.5). This standard was proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Standardization Technical Committee for Measuring Instruments (SAC/TC132). This standard is drafted by. Chengdu Chengquan Tools Group Co., Ltd.
