National Metrology InstituteUME is the National Metrology Institute (NMI) of Turkey and operates under the auspices of TUBITAK (Scientific and Technological Research Council of Turkey).

Efforts to establish a modern metrology institute in Turkey began in 1983. The National Metrology Institute was officially founded in August 1986.

Main Problems on Pressure Metrology

Let’s turn back to main tasks

Development and maintenance of an effective metrological infrastructure as required for Turkey’s

accession to the European Union in the field of pressure metrology

What kind of problems

we have been met???

QuestionsWhere is the uncertainty of repeatability

on the certificate? Ask the UME..

Assessor from country A

Certificate does not have to give the unc. of rep.Why do you ask?

You have to calculate the unc. of rep. Assessor from country B

Assessor from country CThere is no need to unc. of rep. for secondary

DWT.One cycle is enough…

CUSTOMERS ARE CONFUSED…
