NoBoMet is a European platform of Notified Bodies working in legal Metrology. These bodies can be governmental agencies, but also private commercial organisations. Also the range of activities can vary from single verification to Type Approval and Quality System Approval.
Bodies designated by their national authority for conformity assessment of measuring instruments, establish in this platform interagency communication to optimize the circumstances and conditions under which the Notified Bodies operate and to make this transparent for the manufacturers of measuring instruments for which conformity assessment is regulated.
Governmental Authorities, National Accreditation Bodies, OIML and WELMEC have well established interoperability capabilities and mutual agreements in place. While these agreements formally extend beyond conformity assessment, they tend to remain governmental controlled and nationally oriented in practice. Today’s reality highlighted the need for a prompt communication platform on topics encountered by Notified Bodies performing conformity assessment of measuring instruments.
To improve mutual confidence between the bodies and countries in conformity assessment, the bodies have worked cooperatively on a communication platform for this branch. This platform establishes a common communication channel from and to the members on topics that are encountered in practice. This platform strives for international acknowledgement and recognition by governing organisations, public officials and public authorities. In this way, this platform will take care of general interests of the members.
Frequently asked questions
The International Organization of Legal Metrology (OIML) is an intergovernmental treaty organization whose membership includes Member States, countries which participate actively in technical activities, and Corresponding Members, countries which join the OIML as observers. On voluntary basis notified bodies can be authorized as Issuing Authority for Type Examination of measuring instruments within the OIML certification system.OIML certificates of conformity may be accepted by national authorities to establish national approval.
To establish harmonized and consistent approaches on the conformity assessment in legal metrology, the European cooperation of national authorities “WELMEC” provide guidance to the notified bodies and inspection bodies. In some cases notfied bodies participate in WELMEC meetings or technical committees as being the national authority. In other cases the notified body participate on behalf of the national authority, or do not participate at all.
At present two European directives are in force for measuring instruments; DIRECTIVE 2014/31/EU of the European Parliament and of the Council of 26 February 2014 on Non-Automatic Weighing Instruments and DIRECTIVE 2014/32/EU of the European Parliament and of the Council of 26 February 2014 on Measuring Instruments. The latter covers water meters, gas meters and volume conversion devices, active electrical energy meters, heat meters, measuring systems for continuous and dynamic measurement of quantities of liquids other then water, automatic weighing instruments, taximeters, material measures, dimensional measuring instruments and exhaust gas analysers. In general the directives are called the NAWI and MID directives.
Conformity assessment is any activity to determine that a process, product, or service meets relevant technical standards and fulfills relevant requirements. Conformity assessment activities may include testing, inspection, auditing and certification.
Notification is an act whereby a Member State informs the Commission and the other Member States that a body, which fulfills the relevant requirements, has been designated to carry out conformity assessment according to a directive. A list of notified bodies, including the designated tasks, is available on the Nando website of the European Commission.
Legal metrology comprises all activities for which national legal requirements are prescribed on measuring instruments and methods of measurement. These activities are in Europe performed by designated and notified bodies on behalf of governmental authorities, in order to ensure an appropriate level of credibility of measurement results within Europe. The requirements and method of measuring are for number of measuring instruments harmonised by European directives.
