Law 3/1985, of March 18, of Metrology, establishes the legal regime of the metrological activity in Spain, to which they must submit in defense of the safety, the protection of the health and the economic interests of the consumers and users, the measuring instruments under the conditions which they are determined to determine. This Law was subsequently developed by various norms of metrological content, among which is the Royal Decree 1616/1985, of 11 September, establishing the metrological control carried out by the State Administration.

Council Directive 92/55/EEC of 22 June 1992 amending Directive 77 /143/EEC on the approximation of the laws of the Member States relating to the technical control of motor vehicles and motor vehicles its trailers (exhaust emissions), determines emission limits for exhaust gases of vehicles equipped with spark-ignition engines, with or without a catalyst. In addition, the Directive lays down the requirement to use equipment capable of accurately controlling the limits of the pollution of gases emitted by vehicles of the prescribed, prescribed operating characteristics. by the builders. This Directive was incorporated into national law by the Order of the Ministry of Industry, Commerce and Tourism of 24 July 1992.

For its part, the text of the Law on Traffic, Circulation of Vehicles to Motor and Road Safety, approved by Royal Decree 339/1990 of 2 March, expressly prohibits in its article 10.5 the issuance of Gas in urban and inter-urban roads above the established limits.

It follows from all of the above the need for, from a metrological point of view, to regulate the requirements that these instruments must meet to overcome the State's metrological control and to be able to be used to measure emissions of exhaust gases from vehicles equipped with spark-ignition engines (petrol).

The processing of this Order has been followed by the procedure for information on technical standards and regulations laid down in Directive 83 /189/EEC of 28 March of the European Parliament and of the Council and of the European Parliament. Decree 1168/1995 of 7 July.
