Περίληψη:	During the EURAMET TC Flow meeting, held in Scotland in March 2010, it was agreed to start a comparison with a 1000 L proving tank in order to compare results, uncertainties and calibration methods. Both the gravimetric method and the volumetric method were used by several laboratories. Within EURAMET it is the first time that a comparison is organised in the large volume capacity range. So far there have been only EURAMET comparisons in the μL range, and volumes of 100 mL, 5 L and 20 L. Compared to small volume standards, the calibration of large proving tanks involves a number of circumstances that may vary considerably between the laboratories (type and preparation of water and its actual temperature, control of surrounding air temperature and humidity, practical handling, different surface conditions inside, techniques to read the scale, use of balance or volumetric standards etc.). The Portuguese and Dutch Metrology Institutes, IPQ and VSL, were the coordinators of this comparison. VSL, acting as the pilot laboratory, performed the initial and final measurements on the 1000 L proving tank. The project protocol was sent to all the EURAMET TC Flow members and 11 NMIs agreed to participate. During the comparison two other NMIs joined and one withdrew due to customs problems. The circulation of the 1000 L proving tank started in September 2010 and ended in June 2012. Each NMI had one month to perform the calibration of the 1000 L proving tank.
