The phrase "accredited calibration" is correct and usable in written English.
It can be used in contexts where you are referring to calibration services or processes that have been officially recognized or certified by a relevant authority.
Example: "The laboratory offers accredited calibration services to ensure the accuracy of measurement instruments."
Alternatives: "certified calibration" or "official calibration".
The radioactivity of this source was calibrated with a Germanium-semiconductor spectrometer at an accredited calibration center (Japanese Radioisotope Association, Tokyo, Japan); the level of uncertainty in the measurement was <1.5%% (k = 2).
Irradiations were carried out by the accredited calibration laboratory VSL (Dutch national metrology institute/Delft).
A pneumatic pressure proficiency test for effective area determination of a pressure balance was performed among 4 accredited calibration laboratories in Mexico.
The paper provides comparison of the optical encoder reference technique to manufacturer's accredited primary calibration of an artifact as per ISO 16063-11.
It was calibrated at a national measurement institute and used to compare the two possible realisation schemes (i.e. radiation thermometer calibrated to ITS-90, and the same thermometer calibrated using high temperature references) to the local ITS-90 scale at an accredited industrial calibration laboratory.
As part of BUPLAS accreditation, all candidate calibration results are recorded so their performance over time is tracked and they are accredited as calibrated once they are consistently within the calibration threshold (.5 measure on BUPLAS).
Experimental measurements are carried out in an accredited laboratory for calibration of rate flow meters and a metrological validation, followed by an uncertainty evaluation, are presented.
Both the ionization chamber and the electrometer were calibrated by Accredited Dosimetry Calibration Laboratory (ADCL) at the University of Wisconsin.
All methods were fully automated with automatic calibration and accredited laboratory facilities [ 12].
The laboratory is fully accredited (Clinical Pathology Accreditation), performs daily calibration, internal quality control and participates in External Quality Assessment.
Many measurements were performed in collaboration with the Radionuclide Metrology Laboratory (RML) from IFIN-HH, RENAR accredited and CNCAN notified for calibration and for testing in the field of radioactivity measurement.
