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.
