17、75:2016 (E) 4 Annex ZA (informative) Relationship between this European Standard and the Essential Requirements of EU Directive 93/42/EEC OJ L 169 aimed to be covered This European standard has been prepared under a Commissions standardization request M/023 concerning the development of European sta

18、ndards related to medical devices to provide one voluntary means of conforming to essential requirements of Council Directive 93/42/EEC of 14 June 1993 concerning medical devices OJ L 169. Once this standard is cited in the Official Journal of the European Union under that Directive, compliance with

19、 the normative clauses of this standard given in Table ZA.1 confers, within the limits 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

20、to the risk management process is made, the risk management process needs to be in compliance 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

21、the corresponding essential requirement. NOTE 2 The manufacturers policy for determining acceptable risk has to 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

22、the European foreword, replacing the references in the core text. NOTE 4 When an Essential Requirement does not appear in Table ZA.1, it means that it is not addressed by this European Standard.
