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].
This document is an adoption of an International Standard. As the scope of the applicable regulatory
requirements differ from nation to nation and region to region, the scope of this document can differ
from the scope of the European Regulations that it supports. This document supports European
regulatory requirements only to the extent of the scope of the European regulations for medical devices
((EU) 2017/745).
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.

of this EN
(EU) 2017/745
11.3 4,5,6,7,8,9 This standard addresses the
determination of bioburden in the
validation and maintenance of a
sterilization process for medical
devices. It could also be applied in the
development, validation and routine
control of a process for attainment of a
specific microbial state other than
sterility.
This relevant General Safety and
Performance Requirement is only
partly addressed in this European
Standard. Design and packaging for
maintenance of a specific microbial
state during transportation and storage
are not covered. Aspects of
manufacture other than those related
to determination of bioburden in
attainment of a specific microbial state
are not covered.
11.4 first sentence only 4,5,6,7,8,9 This standard addresses the
determination of bioburden in the
validation and maintenance of a
sterilization process for medical
devices.
This relevant General Safety and
Performance Requirement is only
partly addressed in this European
Standard. Design and packaging for
maintenance of sterility during
transportation and storage are not
covered. Aspects of manufacture other
than those related determination of
bioburden in definition, validation and
maintenance of a sterilization process
are not covered. Evidence that the
integrity of the packaging is maintained
to the point of use is not covered.
11.5 4,5,6,7,8,9 This standard addresses the
determination of bioburden in the
validation and
maintenance of a sterilization process
for medical devices.
This relevant General Safety and
Performance Requirement is only
partly addressed in this European
Standard. Packaging for maintenance of
sterility are not covered. Aspects of
manufacture other than those related
to determination of bioburden in
definition, validation and maintenance
of a sterilization process are not
covered.
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.
Annex ZB
(informative)
Relationship between this European standard and the General Safety and
Performance Requirements of Regulation (EU) 2017/746 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) 2017/746 of 5 April 2017 concerning in vitro diagnostic medical devices [OJ L 117].
This document is an adoption of an International Standard. As the scope of the applicable regulatory
requirements differ from nation to nation and region to region, the scope of this document can differ
from the scope of the European Regulations that it supports. This document supports European
regulatory requirements only to the extent of the scope of the European regulations for in vitro
diagnostic medical devices ((EU) 2017/746).
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 ZB.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) 2017/746. This means that risks have to be
