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.
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
In the field of information technology, ISO and IEC have established a joint technical committee. ISO/IEC JTC 1.
Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75% of the national bodies casting a vote.
International Standard ISO 12215 was prepared by Technical Committee ISO/TC 188, Small craft.
Beside this second part, ISO 12215 consists of
Part 1: Materials - Thermosetting resins, glass fibre reinforcement, reference laminate
Part 3: Materials - Steel, aluminium, wood, other materials
Part 4: Workshop and construction
Part 5: Design pressures, allowable stresses, scantling determination
Part 6: Details of design and construction
Introduction
The reason underlying the preparation of this International Standard is that sandwich structures of recreational 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.
