introduction
JJF1002-2010 "national verification procedures write rules", JJF1001-2011 "common terminology and measurement
Definitions ", JJF1059.1-2012" Evaluation and Expression of Uncertainty in Measurement ", JJG 22-2003" inside micrometer inspection
Setting rules "(hereinafter referred to as the original regulations) constitute the basis of technical regulations of the series metering regulations revision.
This procedure is JJG 22-2003 amendments. Compared with JJG 22-2003, in addition to editorial changes outside the main technical
Surgery changes are as follows:
--- According to GB/T 22093-2008 "electronic digital micrometer diameter" and GB/T 8177-2004 "points
Inside micrometer "newly added electronic digital display device" consistent value drift "and" digital value and differential cylinder readings
Of "verification project, while increasing technical requirements and test methods corresponding to the project.
--- According to GB/T 8177-2004 "points inside micrometer" Edit "groove width and width difference" Without
Fixed tube diameter with the same requirements.
--- Edit "change indication error indication micrometer head and locking device locking and release time" is shown in the micrometer head
Error requirements.
--- Edit "micrometer head and the ground pole combination of size" to "indication error", do not use the checking of inspection.
--- According to GB/T 8177-2004 "points inside micrometer" modified "show error" and "rigid lead
From the length of the change in size, "the technical requirements.
