introduction
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 "together constitute the support of the calibration code revision
Basic series of normative work.
The code revision, the main reference standard JB/T 10007-2012 "Great outside micrometer (measuring range
1000mm ~ 3000mm) "and GB/T 1216-2004" outside micrometer ", this specification replace JJF 1088-
2002 "outside micrometer (measuring range 500mm ~ 3000mm) calibration specification."
Compared with JJF 1088-2002, in addition to editorial changes, the main technical specification of the changes are as follows.
--- Name specification to "large outside micrometer calibration specification."
--- Large size outside micrometer overview has been modified.
--- Remove the "radial and axial movement of the micrometer screw swing" and "groove width and a width between" the two
index.
--- Increased by gantry measuring "return error indication table" approach jog.
--- Anvil surface and measuring the relative offsets micrometer screw measuring surface index has been modified.
--- Increase with large table outside micrometer anvil activity indicator measuring the force at the contact plane and spherical, and measure
Changes within their means giving provisions.
--- Surface roughness measuring surface according to the type of material, the shape of the surface can vary somewhat.
--- For measuring surface flatness index has been modified.
--- Indicators parallelism of two micrometer diameter measuring surface has been modified.
--- Indication error indicators micrometer head has been modified.
--- Large size outside micrometer indicators and calibration method error of indication has been modified.
--- Indicators proofreading amount Rod Size deviation has been modified.
--- Canceled proofing dipstick parallel index requirements.
--- Face of two parallel calibration method were refined.
--- The amount of block size micrometer indication when using error correction were perfect with GB recommended values of unity.
--- Re-measurement of Uncertainty about Indication Error assessed.
JJF 1088 of previously issued as follows.
