Interlaboratory comparison on the calibration of masses targets accredited calibration laboratories (according to ISO 17025) but also testing and analysis laboratories carrying out their own calibrations and / or controls of their own masses. This proficiency testing is COFRAC accredited, according to No. 1-7127 (scope available on www.cofrac.fr).
Mass calibration PT
The nominal masses of the entities to be calibrated in this inter-laboratory comparison are:
5mg, 50mg, 500mg, 5g, 50g, 500g et 5kg
Calibration by comparison
The most appropriate calibration method is the comparison of the mass to be calibrated with a standard mass of equivalent nominal value, using a comparator or a balance. Numbers of repetitions and calibration cycles are left to the participant's choice. His own procedure must be used as well as his own calibration means (standards, comparators/balances).
Participants may register for one or more masses; it is not mandatory to calibrate all the proposed entities. In addition, any laboratory may participate, regardless of its uncertainty.
A detailed protocol will be provided to each participant at the beginning of the campaign.
Each participant must calibrate the masses within one or two weeks. All the masses will circulate successively from one participant to the other.
