Coverage of Essential Requirements of EU Directives
This European Standard has been prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association to provide a means of conforming to the
Essential Requirements given in Annex I of the EU Directives 93/42/EEC as amended by 2007/47/EC.
General Guidance:
Once this standard will be cited in the Official Journal of the European Union under that Directive,
compliance with the clauses of this standard given in Table ZZ.1 confers, within the limits of the scope
of this standard, a presumption of conformity with the corresponding Essential Requirements (ERs) of
that Directive and associated EFTA regulations.
NOTE 1 This standard is intended to be applied in its entirety only. Selected clauses or
subclauses may be not applicable due to the specific type of equipment under consideration. It is
necessary to understand and apply Clauses 1 to 5. It is also recommended to understand and apply
those clauses which contain general requirements related to a specific subclause. Elements of the
standard that are not cited in Table ZZ.1 may be relevant for the appropriate fulfilment of certain
essential requirements through indirect reference, and for safety and performance aspects of the
device, that are not addressed through essential requirements.
NOTE 2 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 to the MDD (Directive 93/42/EEC
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 3 With respect to Note 4 of 4.2.2 General requirement for risk management, 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 4 References in the Clauses 3 to 17 or in the Annexes of this standard specify whether
the normative references listed in Clause 2 as cited in Annex ZA are to be applied in whole or in part.
NOTE 5 This Annex ZZ is based on Normative References according to Annex ZA, replacing
the references in the core text.
NOTE 6 According to the scope of this standard the coverage in Table ZZ.1 only applies to the
design and construction of HEARING INSTRUMENTS or HEARING INSTRUMENT SYSTEMS. This
European Standard lists in Table ZZ.1 only the essential requirements covered.
WARNING: Other requirements and other EU Directives and Regulations may be applicable to the
product(s) falling within the scope of this standard.
