JJF 1071-2010 "National Calibration Specifications writing rules", JJF 1001-2011 "common terminology and measurement Definitions ", JJF 1059.1-2012" Evaluation and Expression of Uncertainty in Measurement "constitute support calibration code revision work As a series of basic norms. JJF 1411-2013 "Measurements within micrometer calibration specification" (hereinafter referred to as "the Rules") identical with GB/T 6314-2004 "claw inside micrometer", JB/T 10006-1999 "Niece micrometer" modify the use of GB/T 22093-2008 "electronic digital inside micrometer", this specification replace JJF 1091-2002 "within Measurements Micrometer calibration specification. " Compared with JJF 1091-2002, in addition to editorial changes, the main technical specification of the changes are as follows. --- Three o'clock inside micrometer measuring range to 300mm, electronic digital Niece micrometer range increase To 200mm. --- Internal micrometer size outline configuration diagram of a larger changes, consistent with the new structure now. --- "Indication error" and other technical indicators by GB/T 22093-2008 "electronic digital inside micrometer" JB/T 10006-1999 "Niece micrometer" requirements identical with. --- "Proofreading ring diameter" size requirements and technical specifications of a larger change, tantamount to the adoption GB/T 22093-2008 "electronic digital micrometer diameter" national standards. --- Increase in the size of electronic digital micrometer "segment error" and "value drift" two technical requirements. --- Increased international recommendations 10.00 recommended amount requested block size indication error test method. --- Increased electronic digital three-point internal micrometers and electronic digital display shows error measured uncertainty micrometer assessment. --- Original specification measuring three micrometer diameter ring gauge sizes used in poor operability, the new version has been removed.

Its shape structure shown in Figure 1. Electronic digital Niece micrometer screw is rotated by a lieutenant movement into two arc-shaped measuring surfaces along the axis of rotation Linear motion parallel to the use of angle sensors, electronic and digital display technology, calculate and display two measuring surface divided Internal dimensions measuring instruments distance. Its shape structure shown in Figure 2. Three-point inside micrometer screw pair by the steering mechanism and the rotary motion into three arcuate surface along a measuring spin Linear motion perpendicular to the axis of rotation, and three arc-shaped measuring surfaces constituted within the cylinder diameter size measurement instrument readings. Its shape structure shown in Figure 3. Electronic digital three o'clock micrometer diameter by screw pair and the steering mechanism rotary motion into three arcuate measure Linear movement along a plane perpendicular to the axis of rotation, the use of an angle sensor, and an electronic digital display technology, is calculated and displayed Three arc-shaped cylindrical measuring surface constituting the inner diameter dimension measuring instruments.
