Abstract
The results of the comparison of parallel thread gauges
between ten European countries are presented. Three
thread plugs and three thread rings were calibrated in
one loop. Croatian National Laboratory for Length
(HMI/FSB-LPMD) acted as the coordinator and pilot
laboratory of the comparison. Thread angle, thread pitch,
simple pitch diameter and pitch diameter were measured.
Pitch diameters were calibrated within 1a, 2a, 1b and 2b
calibration categories in accordance with the EURAMET
cg-10 calibration guide. A good agreement between the
measurement results and differences due to different
calibration categories are analysed in this paper. This
comparison was a first EURAMET comparison of parallel
thread gauges based on the EURAMET ctg-10 calibration
guide, and has made a step towards the harmonization of
future comparisons with the registration of CMC values
for thread gauges.
