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. JJF 1088-2002 "outside micrometer (measuring range 500mm ~ 3000mm) calibration standard" JJG193-1987 micrometer (measuring range 500mm ~ 3000mm) (Trial) Large outside micrometer calibration specification
