Theses standards specify the tolerances and limits for simple forms of thread gauges, such as:
Parallel thread plug gauges
Parallel thread ring gauges
It is highly recommended that an appropriate authority such as a UKAS approved laboratory carries out a full calibration on thread gauges at least once a year. In between UKAS calibrations at a frequency based on usage, thread gauges should be calibrated in-house. A typical in-house calibration would include a written procedure and an associated calibration record sheet, which would contain as a minimum, the following listed information:
(a) Serial number
(b) Location
(c) Procedure number
(d) Rate and compression correction
(e) Gauge tolerance
(f) Results
(g) Measurement uncertainty
(h) Sentence if appropriate
(i) Date and calibrators signature
(j) Traceability to National Standards
It is necessary that any person carrying out such calibration work should have received appropriate training and have shown the ability to be confident via a suitable training authority. Training records should be held and maintained.
Following are layouts for typical in-house calibrations for thread gauges:
