The National Metrology Institute of Turkey (UME) has it roots in calibration and measurement standards laboratories that began operations in 1982 within a larger research institute, and

was formally established as a separate institute tied to the Scientific and Technological Research Council of Turkey (TÜBITAK) in 1986 for the purposes of facilitating the development

of the high-technology production capacity of our country’s industrial sector, and to build and develop the national measurement and metrology infrastructure. UME was established to be a primary level measurement center to meet the

needs of the Turkish Armed Forces in addition to both private and public sector entities. UME, which has strived to meet the demands of the defence industry through the supply of calibration, testing, repair/maintenance services, as well as training and consulting

in the field of metrology, has also aimed at making a contribution to the development of new technologies through the adoption of the newest

techniques in measurement and calibration. With 25 years of accumulated knowhow, an expert team of researchers and experienced staff, UME not only supports Turkish industry but has also

become a well-accepted institute in the

world of metrology by becoming a leader in its region through sharing its experience and expertise with neighboring countries. UME has adopted an important role since its establishment both on the national and international scenes, and successfully fulfills the duties that necessarily follow from this role:

• To establish and maintain national measurement reference standards in accordance with the internationally accepted definitions of basic

and derivative International

System of Units (SI Units).

• To engage in R&D activities in the areas of measurement technologies and metrology in line with scientific developments and national needs for the purposes of supporting our industry and making a contribution to the world of metrology.

• To ensure the integration of the national measurement system with the international system and to promote its recognition.

• To support the development of Turkey’s quality and metrology infrastructure to increase the competitive strength of domestic products

on the international market.

• To promote societal awareness of metrology with the aim of improving quality of life.

• To represent Turkey internationally in the area of metrology. Within the framework of its duties, UME has expended considerable effort

to ensure that our industrial products are domestically and internationally competitive by supporting industrial establishments. The institute, which has built measurement systems and devices in addition to establishing

measurement reference standards, also directly transfers know-how to industrial establishments through setting up collaborative arrangements at

the stage of product development. UME maintains a multi-disciplinary working area. UME possesses a total of 40 laboratories within an enclosed

area of 28,000 square meters that carry out work in the areas of chemical, mechanical, physical, and electrical metrology. These laboratories are as follows:

The Chemistry Group:

• Organic Analytical Methods


• Inorganic Analytical Methods


• Classical Analytical Methods


• Gas Metrology

The Electrical Group:

• Electromagnetic Metrology

• Voltage Group Laboratories

• Impedance Group Laboratories

The Mechanics Group:

• Force Group Laboratories

• Mass Group Laboratories

• Pressure Group Laboratories

• Dimensional Group Laboratories

• Fluid Mechanics Laboratory

• Acoustics Group Laboratories

The Physics Group:

• Contact Thermometry Laboratory

• Radiation Thermometry


- Humidity Laboratory

- Magnetism Group Laboratories

- Optics Group Laboratories

UME laboratories employ experienced researchers with expertise in chemistry, physics, mechanical and electrical engineering that constitute 52% of

the total workforce. UME, which has kept pace with developing technologies since its inception

and now possesses a well evelopedinfrastructure, takes an active role in defence industry projects and product development processes of civil industry by making use of its multi-disciplinary workforce and laboratories. The institute employs its infrastructure to perform more than 4000 calibrations, publish more than 25 scientific articles in respected nternational journals, and participate in over 25 ternational

measurement intercomparisons every year.

UME maintains an active customer base of over 500 establishments, memberships in 71 national and international technical committees, and 105

primary level measurement standards. Of UME’s primary level standards, its atomic clocks contribute to the determination of World Time. Time production is realized at an accuracy of 1x10- 14, and is disseminated nationally at

an accuracy under 5 ms (using NTP protocol over the Internet at http://time.ume.tubitak.gov.tr)


The need for the redefinition of the basic and derived units in the SI system has arisen in parallel with developments in technology. For example, while a century ago the unit of length

was linked to the distance between two lines on the meter prototype made of a platinum-iridium alloy, it is now defined in relation to the wavelength of light, upon which the accuracy and

reliability of units derived from the meter are defined. UME participates in international key

comparisons to ensure the international validity of the measurement reference standards it produces. Furthermore, UME, which builds systems

and measurement standards that are accepted worldwide, participates in related research and maintains close contact with technological developments, also takes place in the development

processes of new technologies. For this purpose, UME actively participates in metrology research projects sponsored by the European Union, and

with its young and dynamic workforce, has become an indispensable part of the effort to achieve uniformity in measurements among European

Union and Southeastern Asian institutes

of metrology. aking advantage of its relatively

recent foundation and its use of new echnologies in providing its services,UME has positioned itself as an irreplaceable partner for countries that support the development of metrology services in neighboring countries. In this context, UME provides training for the personnel of institutes of metrology in the Southeastern

European region. UME’S PLACE IN THE WORLD

OF METROLOGY UME works in close cooperation with

leading institutes of metrology on the international recognition of the measurement

standards and systems, which it has developed since its foundation. For this purpose, it participates in international comparisons for all of the national standards it has established.

Furthermore, by signing the CIPM Mutual Recognition Agreement, UME has secured the recognition of its measurements and services in 65 countries that are party to the agreement.

Thus, all of the institutions, establishments and companies whose measurements are traceable to UME have been integrated into the international metrology system.

UME, which has adopted a quality system based on ISO/IEC 17025, has certified itsompliance with this standard through accreditation by the tional accreditation body of Turkey, TÜRKAK, and has received its 17025 compliance certificate.

UME provides technical experts to participate in TÜRKAK’s accreditation work within the framework of a cooperation protocol signed by both parties.

NEW RESEARCH AREAS AND PROJECTS UME has reached beyond its borders to demonstrate a presence in research that covers not only metrology but also

other areas that in some way are related to the science of measurement. Some of the research that is underway or planned for the future involves the following subjects:

• Chemical Metrology – Biological


• Legal Metrology – Measurement

systems in compliance with directives

on measurement devices

• New Temperature Reference


• New Mobile He-Ne/I1272

Stabilized Laser

• Development of the National “g”


• Optic Measurement Systems

• Sensor Technologies

Following are examples of projects

developed at UME:




UME’s Acoustics Group Laboratories will provide the certification for prototype transducers that are to be produced as part of the National Sonar

Marine Units Production and Integration Project that was developed for the National Defence Ministry of Turkey. UME’s established infrastructure in the area of acoustics constitutes a suitable platform for the project, and work is continuing at full pace towards

its successful completion.


The environmental tests for the sonobuoy that was developed and produced within the context of the National Sonobuoy Development and Production Project are being conducted by UME’s Acoustic Group Laboratories.



A significant contribution has been made to the national budget through this project that aims to prevent the circulation of smuggled petroleum

derivative liquid fuels in Turkey, to improve the quality of fuels on the market, and to reduce foreign dependence by developing the necessary infrastructure for producing and administrating the national marker through domestic resources. Frequent reformulation

of the marker has nullified the risk of chemical copying, and has made the project continuous.

DOLUNAY PROJECT This project was developed in cooperation with the private sector for the purpose of developing quick and reliable testing methods for the analyses of biological fluids for diagnostic purposes. The project has resulted in the development of new techniques and infrastructure that allows for greater speed

in biological tests.


Feasibility studies were conducted for the improvement of the Ministry of Industry and Trade’s Regional Testing Laboratories, and infrastructural work was carried out in the name of the Ministry to de elop new measurement instruments in compliance with relevant directives.


The national measurement reference standards for length, torque, AC and DC resistance, impedance, mass measurement systems, and temperature are

among the primary measurement standards that were developed with the resources and know-how available at UME. These standards allow the measurement of six of the seven fundamental SI units and 65 easurement quantities that are derived of these. The fact that services provided with measurement standards developed at UME are recognized internationally has lead to a demand for these services from other countries. These demands that rise every year are met within the bounds of available capacity. UME also develops projects to produce special surement systems that defence and civilian industries demand based on the know-how and xperience it has accumulated through the velopment of primary level measurement standars.
