Small craft - Hull construction and scantlings - Part 9: Sailing craft appendages (ISO/DIS 12215-9:2024)

ISO 12215-9:2011 defines the loads and specifies the scantlings of sailing craft appendages on monohull sailing craft with a length of hull of up to 24 m, measured according to ISO 8666. It gives design stresses, the structural components to be assessed, load cases and design loads for keel, centreboard and their attachments, computational methods and modelling guidance, and the means for compliance with its provisions.

Petits navires - Construction de coques et échantillons - Partie 9: Appendices des bateaux à voiles (ISO/DIS 12215-9:2024)

L'ISO 12215-9:2011 définit les chargements et spécifie l'échantillonnage des appendices des bateaux à voiles d'une longueur de coque, LH, mesurée conformément à l'ISO 8666, inférieure ou égale à 24 m. Elle fournit: les contraintes de conception, les éléments structurels à évaluer, les cas de chargement et les charges de conception pour la quille, la dérive et leurs éléments de liaison, les méthodes de calcul et des instructions de modélisation et les moyens de se conformer à ses dispositions.

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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
