Annex ZA
(informative)
Relationship between this European standard and the General Safety and
Performance Requirements of Regulation (EU) 2017/745 aimed to be
covered
This European Standard has been prepared under a Commission’s standardization request “M/575” to
provide one voluntary means of conforming to the General Safety and Performance Requirements of
Regulation (EU) 2017/745 of 5 April 2017 concerning medical devices [OJ L 117].
Once this standard is cited in the Official Journal of the European Union under that Regulation,
compliance with the normative clauses of this standard given in Table ZA.1 and application of the
edition of the normatively referenced standards as given in Table ZA.2 confers, within the limits of the
scope of this standard, a presumption of conformity with the corresponding General Safety and
Performance Requirements of that Regulation, and associated EFTA regulations.
Where a definition in this standard differs from a definition of the same term set out in Regulation (EU)
2017/745, the differences shall be indicated in this Annex Z. For the purpose of using this standard in
support of the requirements set out in Regulation (EU) 2017/745, the definitions set out in this
Regulation prevail.
Where the European standard is an adoption of an International Standard, the scope of this standard
can differ from the scope of the European Regulation that it supports. As the scope of the applicable
regulatory requirements differ from nation to nation and region to region, the standard can only
support European regulatory requirements to the extent of the scope of the European regulation for
medical devices (EU) 2017/745).
For application of this European standard under Regulation (EU) 2017/745,
1. it is clarified that the third paragraph of the scope and the related subclause 7.2.1.2 are solely
intended to point out that additional testing not specified in this document can be required to
ensure the safety and efficacy of implants for which failure modes exist which were unknown at
the time of drafting of this document;
2. it is clarified that the fourth paragraph of the scope and related language in the first paragraphs
of Clauses 4, 5, 6 and 7 are intended to avoid unnecessary re-design or re-testing of implants
which are currently legally marketed in the European Union;
3. it is recognized that the normatively referenced ISO 7206-2:2011+Amd 1:2016 itself includes a
reference to the withdrawn ISO 4288:1996 which has been replaced by ISO 21920-3:2021 and
for application of this European standard under Regulation (EU) 2017/745 ISO 21920-3:2021
shall be used instead of ISO 4288:1996;
4. it is recognized that the normatively referenced ISO 10993-1 includes a dated reference to ISO
14971:2007 which is outdated and for application of this European standard under Regulation
(EU) 2017/745 the most recent European version EN ISO 14971:2019 + A11:2021 shall be
used;
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 Regulation (EU) 2017/745. This means that risks have to
be ‘reduced as far as possible’, ‘reduced to the lowest possible level’, ‘reduced as far as possible and appropriate’,
‘removed or reduced as far as possible’, ‘eliminated or reduced as far as possible’, ’removed or minimized as far
as possible’, or ‘minimized’, according to the wording of the corresponding General Safety and Performance
Requirement.
NOTE 2 The manufacturer’s policy for determining acceptable risk must be in compliance with General Safety
and Performance Requirements 1, 2, 3, 4, 5, 8, 9, 10, 11, 14, 16, 17, 18, 19, 20, 21 and 22 of the Regulation.
NOTE 3 When a General Safety and Performance Requirement does not appear in Table ZA.1, it means that it is
not addressed by this European Standard.
Table ZA.1 — Correspondence between this European standard and Annex I of Regulation (EU)
2017/745 [OJ L 117] and to system or process requirements including those relating to quality
management systems, risk management, post-market surveillance systems, clinical investigations,
clinical evaluation or post-market clinical follow-up
