The “Directive 2004/22/EC of the European Parliament and the Council of 31 March 2004 on measuring instruments“ was published on 30 April 2004 in the Official Journal of the European Union and came into force on the same day. Its application by the member states of the European Union and the European Economic Area became effective by 30 October 2006.
The member states of the European Union issue and publish legal and administrative regulations, in order to implement this directive into national law. In Austria this was effected by the ordinance BGBl. (Federal gazette) II No. 274/2006 of the Federal ministry of economy, family and youth (BMWFJ) and the respective verification regulations of the Federal office of metrology and surveying (Bundesamtes für Eich- und Vermessungswesen – BEV) in the Official Bulletin of the Metrology Service No. 3/2006 (special issue).
For the following 10 types of measuring instruments the initial placing on the market and putting into service is regulated by the same requirements Europe-wide:
