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 standardization 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.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation on the meaning of ISO specific terms and expressions related to conformity

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical

Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information

The committee responsible for this document is ISO/TC 172, Optics and photonics, Subcommittee SC 7,

Ophthalmic optics and instruments.

This fourth edition cancels and replaces the third edition (ISO 12870:2012), which has been technically

revised with the following change:

— 8.8 and Annex C are now covered in more specific standards (ISO/TS 24348:2014 and EN 16128:2015,

respectively) and are now included as appropriate reference to this International Standard (see

4.2.3 and Annex C).
