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 standardisation request 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 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.
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 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 a General Safety and Performance Requirement does not appear in Table ZA.1, it means that it is
not addressed by this European Standard.

10.2 is only partly covered by this
standard, since the standard does not
provide requirements on design and
manufacture and does not oblige to
minimize risk.
However, this standard provides a
means of preparing samples to assess
conformity with this part of this general
10.2 (first sentence only) 4, 5, 6, 7, 8, 9, 10 and 11
health and safety requirment in
conjunction with other relevant parts of
ISO 10993 for the design and
manufacture of medical devices.
Packaging is not covered.
Risks from residues to person involved
in the transport or storage of medical
devices are not covered.
10.4.1 is only partly covered by this
standard, since the standard does not
provide requirements on design and
manufacture and does not oblige to
minimize risk.
However, this standard provides a
10.4.1 (First paragraph only) 4, 5, 6, 7, 8, 9, 10 and 11 means of preparing samples of medical
devices to assess conformity with this
part of this general health and safety
requirment in conjunction with other
relevant parts of ISO 10993.
Other forms of toxicity are not dealt
with in this standard.
WARNING 1 — Presumption of conformity stays valid only as long as a reference to this European
standard is maintained in the list published in the Official Journal of the European Union. Users of this
standard should consult frequently the latest list published in the Official Journal of the European
Union.
WARNING 2 — Other Union legislation may be applicable to the product(s) falling within the scope of
this standard.
