Never use a micrometer that has not been calibrated, if in doubt consult an appropriate authority.
External Micrometers BS The manufacturing specifications and associate accuracy requirements of this standard are complex and it may be uneconomical micrometer calibration procedure any company or institution to invest in equipment to the level required in order to calibrate micrometers fully in accordance with the standard.
It is highly recommended that an appropriate authority such as a UKAS approved laboratory carries out a full calibration on micrometers at least once a year. In between UKAS calibrations at a frequency based on usage micrometers should be calibrated in-house.
A typical in-house calibration would include a written procedure micrometer calibration procedure an associated calibration record sheet which would contain as a minimum the following listed information: Procedure Read this entire procedure before beginning the calibration.
Calibration shall be performed in an environment that conforms to Manufacturer Specifications.
Verify that the IUT is clean. Visually examine the IUT for any condition that could cause errors in the calibration. Micrometer calibration procedure yet, calibrations are sometimes based solely on whatever auditors demand.
This approach micrometer calibration procedure companies with the cost of excessive calibration in some areas, while leaving them exposed in other areas where they "undercalibrate".
The paper presents an uncertainty budget driven technique, which determines what attributes of each standard and instrument should be calibrated and to what uncertainty. The technique provides clear, data based documentation of the real calibration needs to management and auditors.
