Annex ZA
(informative)
Relationship between this European Standard 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] 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.
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 the 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 document
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).
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

10.1 a), b) and h) 5 and 6 This standard provides requirements and
recommendations for the chemical
characterization of medical devices as part of a
risk management process, including a qualitative
characterization of the chemicals and materials
used, a quantitative characterization of the
amounts of chemicals and materials used and an
evaluation of chemical release (leachable and
extractable profile) in both the design and
manufacturing processes. This chemical
characterization can be used to define or confirm
chemical specifications [10.1 h)] and evaluate the
risk of toxicity [10.1 a) and b)] and
biocompatibility [10.1 b)]. Flammability [10.1 a)]
is not covered.
For 10.1 b), ADME (absorption, distribution,
metabolism, and excretion) is not covered. .

For 10.1 h), physical specifications are not
covered.
10.2 5 and 6 This standard provides requirements and
recommendations for the chemical
characterization of medical devices as part of a
risk management process, including an evaluation
of the release of contaminants and residues
(composition, leachable and extractable profile)
in both the design and manufacturing processes.
Packaging is not covered. Aspects of
contaminants and residues during transport and
storage are not covered.
10.4.1 (First paragraph, 5 and 6 This standard provides requirements and
first sentence) recommendations for the chemical
characterization of medical devices as part of a
risk management process, including an evaluation
of chemical substances that may be released from
the medical device (composition, leachable and
extractable profile) in both the design and
manufacturing processes.
Particles and wear debris are not covered.
