identical text or by endorsement, at the latest by April 2019, and conflicting national standards shall be
withdrawn at the latest by April 2019.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN ISO 12215-9:2012.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive 2013/53/EU.
For relationship with EU Directive 2013/53/EU, see informative Annex ZA, which is an integral part of
this document.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,

Endorsement notice
The text of ISO 12215-9:2012 has been approved by CEN as EN ISO 12215-9:2018 without any
modification.
Annex ZA
(informative)
Relationship between this European Standard and the Essential
Requirements of Directive 2013/53/EU aimed to be covered
This European standard has been prepared under a Commission’s standardization request M/542
C(2015) 8736 final to provide one voluntary means of conforming to Essential Requirements of Directive
2013/53/EU.
Once this standard is cited in the Official Journal of the European Union under that Directive, 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 Essential Requirements of that
Directive and associated EFTA regulations.
Table ZA.1 — Correspondence between this European Standard and Annex I of Directive
2013/53/EU
Essential Clause(s)/sub- Remarks/Notes
Requirements of clause(s) of
Directive this EN
2013/53/EU
Annex I, Part A, 2.5 – 7.7.1, D.3.4, F.2.4.2 These clauses specify warnings and information to be
Owner’s manual included in the owner’s manual, if relevant.

Annex I, Part A, 3.1 - All clauses This part of ISO 12215 provides requirements for the
Structure strength of monohull sailing boat appendages with

conventional keel configurations. It deals with the design
stresses and structural efficiency of the keel and its
connections.
The load cases correspond to those for most
conventional keel configurations; however they may not
be appropriate in all cases and designers or builders still
need to ensure the suitability of their designs.
Scantlings derived from this standard are primarily
intended to apply to recreational sailing craft.
Dimensioning is regarded as reflecting current practice
provided the craft is correctly handled and operated at
speeds appropriate to the prevailing sea state.
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.

ISO 12215-9:2012(E)
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
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, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 12215-9 was prepared by Technical Committee ISO/TC 188, Small craft.
ISO 12215 consists of the following parts, under the general title Small craft — Hull construction and
scantlings:
 Part 1: Materials: Thermosetting resins, glass-fibre reinforcement, reference laminate
 Part 2: Materials: Core materials for sandwich
