Introduction

JJF 1071-2010 "National Calibration Specifications writing rules", JJF 1001-2011 "common terminology and measurement Definitions ", JJF 1130-2005" geometric measurement equipment calibration Uncertainty Evaluation Guide ", JJF 1094- 2002 "Evaluation of measuring instrument characteristics", together constitute the support of the calibration norm-setting series of basic norms. The specification for the revision, instead of JJG886-1995 "tapered roller bearing ring raceway diameter, angle measuring instrument." Compared with JJG886-1995, in addition to editorial changes, the major technical changes are as follows. --- Based JJG63-2007 "knife-shaped ruler" to cancel the 0 and level 1 requirements. --- Based JJG118-2010 "torsion spring comparator" method of verification, the original value of the change in procedures shown in "test Times the amount of no less than 10 times "to" five times the number of measurements. " --- Indication of the change of uniform requirements to 0.5μm. --- Shows the calibration value of the standard error of the device to pairing diameter gauge. --- Increased in the calibration certificate format page content. The previous versions of this specification published case. JJG886-1995. Tapered roller bearing ring raceway diameter, Angle measuring instrument calibration specification
