Annex ZA
(informative)
Relationship between this European Standard and the Essential
Requirements of EU Directive 2013/53/EU
This European standard has been prepared under a mandate given to CEN by the European Commission
to provide one means of conforming to Essential Requirements of the New Approach Directive
2013/53/EU.
Once this standard is cited in the Official Journal of the European Union under that Directive and has been
implemented as a national standard in at least one member state, 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 relevant Essential Requirements of that Directive and associated EFTA
regulations.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the
work. IS0 collaborates closely with the international Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an lnter-
national Standard requires approval by at least 75 % of the member
bodies casting a vote.
International Standard IS0 8848 was prepared by Technical Committee
ISO/TC 188, Small craft.
NOTE 1 This International Standard specifies requirements and test methods
for remote steering systems as cited in clause 1. More specialized requirements
for such steering systems to be applied to simple outboard motors of 15 kW to
40 kW power are given in a parallel document, IS0 9775, Small craft - Remote
steering systems for single outboard motors of 15 kW to 40 kW power.
