25、n this European Standard and the Essential Requirements of EU Directive 93/42/EEC This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association to provide a means of conforming to the Essential Requirements of Directive 93/42
26、/EEC on medical devices. Once this standard is cited in the Official Journal of the European Union under that Directive and has been implemented as a national standard in at least one Member State, compliance with the normative clauses of this standard given in Table ZA.1 confers, within the limits
27、of the scope of this standard, a presumption of conformity with the corresponding Essential Requirements of that Directive and associated EFTA Regulations. NOTE 1 Where a reference from a clause of this standard to the risk management process is made, the risk management process needs to be in compl
28、iance with Directive 93/42/EEC, as amended by 2007/47/EC. This means that risks have to be reduced as far as possible, to a minimum, to the lowest possible level, minimized or removed, according to the wording of the corresponding essential requirement. NOTE 2 The manufacturers policy for determinin
29、g acceptable risk must be in compliance with essential requirements 1, 2, 5, 6, 7, 8, 9, 11 and 12 of the Directive. NOTE 3 This Annex ZA is based on normative references according to the table of references in the European foreword, replacing the references in the core text. NOTE 4 When an Essentia
30、l Requirement does not appear in Table ZA.1, it means that it is not addressed by this European Standard.
