EN ISO 12215-5:2008

Small craft - Hull construction and scantlings - Part 5: Design pressures for monohulls, design stresses, scantlings determination (ISO 12215-5:2008)

ISO 12215-5:2008 applies to the determination of design pressures and stresses, and to the determination of the scantlings, including internal structural members of monohull small craft constructed from fibre reinforced plastics, aluminium or steel alloys, glued wood or other suitable boat building material, with a length of hull in accordance with ISO 8666, between 2,5 m and 24 m.
It only applies to boats in the intact condition and to craft with a maximum speed equal to or less than 50 knots in fully loaded, ready for use conditions.

Kleine Wasserfahrzeuge - Rumpfbauweise und Dimensionierung - Teil 5: Entwurfsdrücke für Einrumpffahrzeuge, Entwurfsspannungen, Ermittlung der Dimensionierung (ISO 12215-5:2008)

Dieser Teil von ISO 12215 betrifft die Bestimmung von Drücken und Spannungen und Bestimmung der
Dimensionierung für den Entwurf, einschließlich interner tragender Bauteile von kleinen Einrumpf-
Wasserfahrzeugen, die aus glasfaserverstärkten Kunststoffen, Aluminium- oder Stahllegierungen, verleimtem
Holz oder anderen geeigneten Bootsbauwerkstoffen gebaut sind, mit einer Rumpflänge, LH, zwischen 2,5 m
und 24 m nach ISO 8666. Dies betrifft nur intakte Boote.
Dies bezieht sich lediglich auf Wasserfahrzeuge mit einer Höchstgeschwindigkeit ≤ 50 Knoten in voll
beladenem Zustand, mLDC.
Im Allgemeinen muss die Beurteilung alle Teile des Wasserfahrzeuges einschließen, bei denen vorausgesetzt
wird, dass sie wasserdicht oder wetterfest sind. Dies trifft bei der Beurteilung von Stabilität, Freibord und
Auftrieb nach ISO 12217 zu und bezieht sich auf alle Teile, die unentbehrlich für die Sicherheit des
Wasserfahrzeugs und Personen an Bord sind.
Für die vollständige Dimensionierung des Wasserfahrzeugs wird dieser Teil von ISO 12215 in Verbindung mit
Teil 6 für Details angewendet. Teil 7 für Mehrrumpfwasserfahrzeuge, Teil 8 für Ruder und Teil 9 für Anhänge
und Takelagezubehör müssen ebenfalls angewendet werden.
Die Bestimmung der Dimensionierung für Fenster, Bullaugen, Blenden, Luken und Türen müssen nach
ISO 12216 erfolgen. Die Konstruktion, die diese Bauteile stützt, muss nach diesem Teil von ISO 12215
erfolgen.
ANMERKUNG 1 Dimensionierungen, die sich aus diesem Teil von ISO 12215 ableiten, sind in erster Linie für
Sportboote einschließlich gecharterter Sportboote gedacht und sind vielleicht nicht für Leistungsrennboote geeignet.
ANMERKUNG 2 Dieser Teil von ISO 12215 basiert auf der Annahme, dass die Dimensionierung ausschließlich von
den lokalen Lasten abhängt.

Petits navires - Construction de la coque et échantillonnage - Partie 5: Pressions de conception pour monocoques, contraintes de conception, détermination de l'échantillonnage (ISO 12215-5:2008)

La présente partie de l'ISO 12215 s'applique pour la détermination des pressions et contraintes de conception, et pour la détermination de l'échantillonnage, y compris les raidisseurs de la structure intérieure, des bateaux monocoques construits en plastique renforcé, alliages d'aluminium et d'acier, bois collé, ou autres matériaux convenant à la construction des bateaux d'une longueur de coque de 2,5 m à 24 m, déterminée conformément à l'ISO 8666.
Elle ne s'applique qu'aux bateaux à l'état intact et qu'aux bateaux d'une vitesse maximale de 50 nœuds en conditions.
