Used Gauge Block Calibration
To ensure compliance with BS EN ISO 17025:2017 quality assurance procedures, it is essential to have gauge blocks recalibrated at regular intervals.
The Broomfield recalibration service includes:
On receipt each gauge is cleaned and inspected by a technician.
If required the gauge will be lightly lapped to remove burrs which may affect accurate measurements or wringability.
For UKAS Class 'C' recalibration, the process continues as with new gauge blocks.
Gauges calibrated to UKAS Class 'A' are checked by interferometry on both gauging faces.
Out of Tolerance Gauge Blocks
While Broomfield will always treat out-of-tolerance gauges in accordance with each customer's own quality assurance standards, it is recommended that gauges found to be out of tolerance are replaced so as to prevent the downgrading of the entire set.
