Page 12 EN 12560-4:2001 BSI 03-2001 Annex A (informative) A-deviations This European Standard is mandated under the Council Directive on the approximation of the laws of the Member States concerning pressure equipment. A-deviation: National deviation due to regulations, the
47、 alteration of which is for the time being outside the competence of the CEN/CENELEC member. NOTE (from CEN/CENELEC) IR Part 2, 3.1.9): Where standards fall under EC Directives, it is the view of the Commission of the European Communities (OJ No G 59, 9.3.1982) that the effect of the decision of the
48、 Court of Justice in case 815/79 Cremonini/Vrankovich (European Court Reports 1980, p. 3583) is that compliance with A-deviations is no longer mandatory and that the free movement of products complying with such a standard should not be restricted except under the safeguard procedure provided for in
49、 the relevant Directive. A-deviations in an EFTA country are valid instead of the relevant provisions of the European Standard in that country until they have been removed.
