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 14509-2 was prepared by Technical Committee ISO/TC 188, Small craft.
ISO 14509 consists of the following parts, under the general title Small craft — Airborne sound emitted by
powered recreational craft:
⎯ Part 1: Pass-by measurement procedures
⎯ Part 2: Sound assessment using reference craft
The following part is under preparation:
⎯ Part 3: Sound assessment using calculation and measurement procedures

ISO 14509-2:2006(E)
Introduction
The development of this part of ISO 14509 became necessary in order to provide an assessment procedure
which would satisfy the needs of the European Union Directive 2003/44/EC (Amendment to Directive
94/25/EC). The reason for the inclusion of this type of assessment procedure in the Directive is to try to
minimize the economic impact of the Directive on the boating industry, in particular small European boat
builders, while still providing an environmental benefit to the community through lower sound levels.

INTERNATIONAL STANDARD ISO 14509-2:2006(E)

Small craft — Airborne sound emitted by powered recreational
craft —
Part 2:
Sound assessment using reference craft
1 Scope
This part of ISO 14509 specifies the procedures to assess the maximum sound emission of powered
mono-hull recreational craft of up to 24 m length according to one of the two alternative methods defined in
Annex A and Annex B.
This part of ISO 14509 is not applicable for the type testing of outboard motors and of stern drives with
integral exhaust systems.
