Key Benefits:
By Royal Decree 472/1988 of 30 March 1988, the detailed rules for the application of Council Directive 75 /324/EEC of 20 May 1975 on the approximation of the laws of the Member States relating to the Aerosol generators, with all these regulations being integrated into the complementary technical instruction MIE-AP3, of the Regulation of Apparatus to Pressure, approved by Royal Decree 1244/1979, of 4 April.
Subsequently, by Royal Decree 2549/1994 of 29 December 1994, the supplementary technical instruction MIE AP3 was amended in the light of the adoption of Commission Directive 94 /1/EC of 6 January 1994 on the technical adaptation of Directive 75 /324/EEC. In this royal decree, by regulatory economy, the provisions concerning aerosol dispensers were included in a single regulatory text.
Recently, Commission Directive 2008 /47/EC of 8 April 2008 has again amended, in order to adapt it to technical progress, Directive 75 /324/EEC on aerosol dispensers.
The most important changes introduced by this Directive are the acceptance of alternative methods of inspection to the hot water bath for the conditioned aerosol dispensers and the establishment new criteria for the flammability of aerosols taking into account not only the physical and chemical properties of their contents but also the conditions of use and, where appropriate, the examination of the risk resulting from the inhalation of the normal or reasonably foreseeable conditions of use, issues which had not been as defined in the previous amendment by Directive 94 /1/EC.
Directive 97 /23/EC of the European Parliament and of the Council of 29 May 1997 on the approximation of the laws of the Member States relating to pressure equipment was incorporated into the Spanish legal order by Royal Decree 769/1999, of 7 May, which came to amend Royal Decree 1244/1979 of 4 April, which approved the previous Regulation of pressure equipment. Although the Royal Decree, 769/1999 of 7 May, refers to the design, manufacture and conformity assessment of pressure equipment with a maximum permissible pressure of more than 0,5 bar, with the exception of its scope to the generators of aerosols. This Directive has led to the need to revise national legislation on pressure equipment to modify, inter alia, its scope, which is defined only for installation, periodic reviews, modifications and repairs. Therefore, it could not be included in the pressure equipment regulation, which was recently approved by Royal Decree 2060/2008 of 12 December, a complementary technical instruction (ITC) relating to manufacturing requirements. Hence the need to establish an independent regulation for aerosol dispensers outside the new pressure equipment regulation.
By regulatory economy, it is considered appropriate to include in a single regulatory text the provisions relating to aerosol dispensers, including the provisions of Directive 75 /324/EEC, as amended for its adaptation to technical progress by Directives 94 /1/EC and 2008 /47/EC. At the same time, in accordance with Article 30 et seq. of the Treaty establishing the European Community (TEC), they shall be admitted on the Spanish market, in addition to aerosols manufactured in accordance with this provision, those other which may be manufactured and controlled in accordance with the technical regulations of the Member States, provided that they guarantee and are recognised at least the same level of protection and security as the one reached with the legislation that is now set.
In the project phase, this royal decree has been submitted to the hearing procedure prescribed in article 24.1.c) of Law 50/1997 of 27 November, of the Government and the autonomous communities have been consulted. It has also issued a favourable report on the royal decree of the Industrial Security Coordination Council.
This provision is dictated by the provisions of Article 149.1.13. of the Spanish Constitution, which attributes to the State the competence to determine the bases and coordination of the general planning of the activity. Article 149.1.10. of the Constitution, which attributes exclusive competence to the State in matters of foreign trade, without prejudice to the powers of the autonomous communities in matters of industry.
This regulation is of a basic regulation and contains forecasts of an exclusive and markedly technical nature, and the law is therefore not the ideal instrument for its establishment and its approval is justified. by royal decree.
