Law 3/1985, of 18 March, of Metrology, establishes the legal regime of the metrological activity in Spain, regime to which they must submit in defense of the safety, the protection of the health and the economic interests of consumers and users, the measuring instruments, under the conditions to be determined. This Law was subsequently developed by various norms of metrological content, among which is the Royal Decree 889/2006, of July 21, which regulates the metrological control of the State on measuring instruments.

This royal decree transposing into national law Directive 2004 /22/EC of the European Parliament and of the Council of 31 March 2004 on measuring instruments, while adapting the metrological control phases concerning the approval of a primitive model and verification, in the instruments subject to national specific regulations, to the system of conformity assessment which is regulated in the said Directive, and also to the development of the the metrological control phases corresponding to the periodic verification and after repair, stages which are not covered by Community legislation.

According to all this, this order is intended to regulate the metrological control of the State on manometers partially equipped with electronic components, intended to measure the pressure of the tires of the vehicles motor, known as electronic tyre gauges, in all the stages covered by the said Royal Decree 889/2006 of 21 July 2006, that is to say, both that which corresponds to the placing on the market and put into service and those relating to verification after repair or modification and periodic verification.

For the elaboration of the order, the autonomous communities have been consulted and the mandatory hearing has been carried out for the interested parties. He has also favourably reported the Metrology Board.

This provision has been submitted to the procedure for information on technical standards and regulations, provided for in Directive 98 /34/EC of the European Parliament and of the Council of 22 June, as amended by the Directive 98 /48/EC of 20 July, as well as Royal Decree 1337/1999 of 31 July, which incorporates both directives into the Spanish legal order.

By virtue,

DISPONGO:

ANNEX IV

Requirements for registration in the Metrological Control Register of persons or entities to repair manometers

Persons or entities that intend to repair or modify the manometers referred to in this order must be registered as authorized repairers in the Metrological Control Registry, as provided by the Royal Decree 889/2006 of 21 July 2006 regulating the metrological control of the State on measuring instruments.

The registration in the Metrological Control Registry will require, on the part of the applicant, the availability of the necessary technical and human requirements to be able to carry out his work and the technical means that allow him carry out the verification of the instrument once repaired and ensure the goodness of the instrument. To do this, you must have at least the following equipment:
