CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn order to validate a new pressure balance based on the piston gauge principle with piston-cylinder unit having large effective area, INRIM decided to partecipate at EURAMET 1047 comparison in the pressure ranges from 1 Pa to 15 kPa. The non-rotating digital piston gauge DHI FPG 8601 serves as the transfer standard in the range (1 Pa - 15 kPa), both gauge and absolute. The transfer standard (of CMI property) and its staff visited INRIM laboratories in the week from 25 to 29 October for the bilateral comparison resulting in a star comparison. A CDG serves as a separator and zero indicator. INRIM participation to the comparison was limited in gauge mode. The present report describes the INRIM results by using DHI FPG 8601 digital piston gauge including the evaluation of the uncertainties
