Annex ZA
(informative)
Relationship between this European standard and the essential
requirements of Directive 93/42/EEC [OJ L 169] aimed to be covered
This European standard has been prepared under a Commission’s standardisation request M/023
concerning the development of European standards 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 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 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 the corresponding essential requirement.
NOTE 2 The manufacturer’s policy for determining 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 Essential Requirement does not appear in Table ZA.1, it means that it is not addressed by this
European Standard.
