METROLOGY Modern metrology is a result of: the development of the industrial type of products manufacturing the increased circulation of goods and commodities

NATIONAL INSTITUTE OF METROLOGY Bucharest June 2005 WORKSHOP IWIRAD 2005 Key conditions to get a high quality in measurements 3 HISTORICAL BACKGROUND A functioning system of weights and measures is a prerequisite for all trade and manufacturing. Until the 19 th century weights and measures were at best harmonised on a national level but quite often local systems prevailed. Industrialisation, mass production of technical goods and increasing cross-border trade called for the creation of a consistent internationally applied system of measuring units. Result: In 1875, the leading industrial nations of those days signed the “Meter Convention”, a diplomatic treaty whereby they agreed to use and promote the Metric system of units, which is now called the “International system of units (SI)”.

NATIONAL INSTITUTE OF METROLOGY Bucharest June 2005 WORKSHOP IWIRAD 2005 Key conditions to get a high quality in measurements 4 By the end of the 19 th century it became obvious that the traditional dissemination of units through “National Offices for Weights and Measures” was no longer sufficient to meet the demand of industry for advanced measuring techniques in particular in the field of mechanics, electricity and optics. METROLOGY INFRASTRUCTURE In 1887, in Germany, a new type of institute was founded, the “Physikalisch-Technische Reichsanstalt” which was dedicated to research and development in the field of metrology to support industry and government. TODAY: Practically all nations operate National Metrology Institutes (NMIs)

NATIONAL INSTITUTE OF METROLOGY Bucharest June 2005 WORKSHOP IWIRAD 2005 Key conditions to get a high quality in measurements 5 National Metrology Institutes (NMIs) have the responsibility to: THE ROLE OF THE NATIONAL METROLOGY INSTITUTE -realise and disseminate the SI system of units to industry and society -conduct research and development for improving the realisation of the SI, in order to meet the needs of industry and society -develop and validate measuring procedures in support of industrial and societal needs and for government directives -give advice to government, society and industry regarding metrological issues

The globalisation of trade and industry, the increased movement of goods and services across state borders or regional limits generates an increasing interest for accurate and reliable measurement results to underpin social and economical development. A global measurement system is needed in which a metrological task is solved world-wide according to the same criteria, i.e. the same physical units, the same product standards, the same calibration procedures and the same calculation of the measurement uncertainties.

This requires harmonisation and mutual confidence ONE-STOP MEASUREMENT Harmonisation Mutual confidence One-stop testing World-wide acceptance of certificates Removal of metrological barriers to trade

In the meantime all the countries have officially introduced the SI metric system, some of them with transition periods. A crucial task of an National Metrology Institute is to realise and disseminate the SI system of units to industry and society providing traceability routes to the SI units with stated measurement uncertainties

The Mars Climate Orbiter mission failed in September 1999: instead of being launched into a stable orbit, the satellite burnt out in the atmosphere of Mars. One reason for the failure was that the control centres in Denver and Pasadena had used different units of measurement, i.e. one team had used the meter and the kilogram, the other the foot and the pound.

NATIONAL INSTITUTE OF METROLOGY Bucharest June 2005 WORKSHOP IWIRAD 2005 Key conditions to get a high quality in measurements 11 In 1999, representatives of 38 national metrology institutes (including INM) and two international organisations signed the “Mutual recognition of national measurement standards and of calibration and measurement certificates issued by national metrology institutes“. Essential points of the MRA are regulations for world-wide key comparisons. The key comparisons are to show the degree of equivalence of national standards and measurement capabilities. Besides the results of key comparisons, a database maintained by BIPM contains information on the calibration and measurement capabilities notified by the NMIs through their regional metrology organisations (RMOs) and reviewed by a Joint Committee of the RMOs and the BIPM. Operation of an efficient QM system is indispensable to ensure that equivalent working methods are always applied and that the confidence is kept up in the intervals between regular comparison measurements. This QM system must fully satisfy the requirements of ISO/IEC THE MUTUAL RECOGNITION ARRANGEMENT (MRA)

NATIONAL INSTITUTE OF METROLOGY Bucharest June 2005 WORKSHOP IWIRAD 2005 Key conditions to get a high quality in measurements 14 CONCLUSIONS Europe spends more than €83 billion per year, or nearly 1% of EU GDP, on measurement activity from directly quantifiable sources alone. Adding in social spending on health, environmental regulation, safety testing, anti- fraud projects and normal day-to-day activity raises this figure considerably. For example each year more than €13 billion is spent on measurement and testing across European health services and a further €5 billion on safety and emissions tests in the 160 million vehicles used by drivers every day in Europe. By comparing these costs with estimates of the benefits of measurement, we can see that this money is well spent. Our econometric estimates of the economic impact of measurement activity show that this spending generates almost €230 billion of directly estimable benefits through application and from the impact measurement knowledge has on technology driven growth. This is equivalent to 2.7% of EU GDP.
