ISO 12215-2:2002(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 3.
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 part of ISO 12215 may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 12215-2 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 construction, embedded materials
 Part 3: Materials: Steel, aluminium alloys, wood, other materials
 Part 4: Workshop and manufacturing
 Part 5: Design pressures, design stresses, scantling determination
 Part 6: Structural arrangements and details
Annex A forms a normative part of this part of ISO 12215.

INTERNATIONAL STANDARD ISO 12215-2:2002(E)

Small craft — Hull construction and scantlings —
Part 2:
Materials: Core materials for sandwich construction, embedded
materials
1 Scope
This part of ISO 12215 specifies requirements for core materials for structural use and materials that are embedded
in sandwich construction. It is applicable to small craft with a hull length (L ) according to ISO 8666 of up to 24 m.
H
NOTE The underlying reason for preparing this part of ISO 12215 is that sandwich structures of small craft require careful
selection of core materials from a multitude of choices, and that the manufacturing has to follow certain procedures to achieve
the intended long-term durability under the expected loads and environmental conditions.
2 Normative references
