Small craft - Stability and buoyancy assessment and categorization - Part 2: Sailing boats of hull length greater than or equal to 6 m (ISO 12217-2:2015)

ISO 12217-2:2015 specifies methods for evaluating the stability and buoyancy of intact (i.e. undamaged) boats. The flotation characteristics of boats susceptible to swamping are also encompassed.
The evaluation of stability and buoyancy properties using ISO 12217-2:2015 will enable the boat to be assigned to a design category (A, B, C or D) appropriate to its design and maximum load.
ISO 12217-2:2015 is principally applicable to boats propelled primarily by sail (even if fitted with an auxiliary engine) of 6 m up to and including 24 m hull length. However, it can also be applied to boats less than 6 m if they are habitable multihulls or may be applied if they do not attain the desired design category specified in ISO 12217‑3 and they are decked and have quick-draining recesses which comply with ISO 11812.
In relation to habitable multihulls, ISO 12217-2:2015 includes assessment of susceptibility to inversion, definition of viable means of escape and requirements for inverted flotation.
ISO 12217-2:2015 excludes:
       inflatable and rigid-inflatable boats covered by ISO 6185, except for references made in ISO 6185 to specific clauses of ISO 12217;
       gondolas and pedalos;
       surfboards including sailing surfboards; and
       hydrofoils and foil stabilized boats when not operating in the displacement mode.
ISO 12217-2:2015 does not include or evaluate the effects on stability of towing, fishing, dredging or lifting operations, which need to be separately considered if appropriate.

Petits navires - Évaluation et catégorisation de la stabilité et de la flottabilité - Partie 2: Bateaux à voiles d'une longueur de coque supérieure ou égale à 6 m (ISO 12217-2:2015)

L'ISO 12217-2:2015 spécifie les méthodes d'évaluation de la stabilité et de la flottabilité des bateaux à l'état intact (c'est à dire non endommagés). Les caractéristiques de flottabilité des bateaux  susceptibles d'envahissement sont également considérées.
L'évaluation des propriétés de stabilité et de flottabilité effectuée à l'aide de l'ISO 12217-2:2015 permettra d'attribuer à un bateau une catégorie de conception (A, B, C ou D) appropriée à sa conception et à sa charge maximale.
L'ISO 12217-2:2015 est principalement applicable aux bateaux propulsés majoritairement par des voiles (même s'ils sont équipés d'un moteur auxiliaire), d'une longueur de coque de 6 m à 24 m inclus. Elle peut cependant être appliquée aux bateaux de moins de 6 m, s'ils sont des multicoques habitables ou s'ils n'atteignent pas la catégorie de conception désirée spécifiée par l'ISO 12217‑3 et s'ils sont pontés et munis de cavités rapidement autovideuses conformes à l'ISO 11812.
Pour ce qui concerne les multicoques habitables, l'ISO 12217-2:2015 comprend l'évaluation de la susceptibilité d'inversion, la définition d'un moyen d'échappée viable et les exigences de flottabilité à l'état inversé.
L'ISO 12217-2:2015 exclut:
       les bateaux pneumatiques et semi-rigides couverts par l'ISO 6185, excepté lorsque l'ISO 6185 fait référence à des articles spécifiques de l'ISO 12217;
       les gondoles et pédalos;
       les planches de surf et planches à voiles; et
       les hydrofoils et les bateaux stabilisés par des plans porteurs lorsqu'ils ne sont pas en mode à déplacement.
L'ISO 12217-2:2015 n'inclut ni n'évalue les effets sur la stabilité provenant du remorquage, de la pêche, du dragage ou d'opérations de levage, qu'il est nécessaire de considérer séparément.

Mala plovila - Stabilnost in ocena vzgona ter kategorizacija - 2. del: Jadrnice s trupom, večjim ali enakim 6 m (ISO 12217-2:2015)

Standard ISO 12217-2:2015 določa metode za oceno stabilnosti in vzgona brezhibnih (nepoškodovanih) čolnov. Zajete so tudi značilnosti plovnosti čolnov, ki so izpostavljeni zalivanju.
Ocena stabilnosti in vzgona z uporabo standarda ISO 12217-2:2015 bo omogočila, da bo čoln vključen v konstrukcijsko kategorijo (A, B, C ali D), ki je ustrezna glede na konstrukcijo in največjo obremenitev.
Standard ISO 12217-2:2015 se uporablja predvsem za čolne na jadra (tudi če imajo nameščen pomožni motor) z dolžino trupa od 6 do vključno 24 m. Uporablja se lahko tudi za čolne, krajše od 6 m, če so večtrupna bivalna plovila, ali kadar niso razvrščeni v želeno konstrukcijsko kategorijo, določeno v standardu ISO 12217-3, in imajo krov ter žlebove za hitro odvodnjavanje, ki so v skladu s standardom ISO 11812.
V povezavi z večtrupnimi bivalnimi plovili standard ISO 12217-2:2015 vključuje oceno izpostavljenosti prevrnitvi, navedbo ustreznih možnosti umika in zahteve za plovnost v prevrnjenem stanju.
ISO 12217-2:2015 se ne uporablja za:
napihljive čolne in napihljive čolne, ki imajo v spodnjem delu trupa togo enoto, ki jih obravnava standard ISO 6185, razen pri sklicih iz standarda ISO 6185 na določene točke standarda ISO 12217;
gondole in čolne na pedala;
deske, vključno z deskami na motorni pogon; ter
hidrogliserje in čolne s stabilizacijskimi flapi, kadar ne delujejo v načinu izpodriva.
ISO 12217-2:2015 ne vključuje ali ne vrednoti vpliva na stabilnost pri vlečenju, ribolovu, črpanju ali dvigovanju, pri katerih je treba ustreznost stabilnosti obravnavati posamezno.

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).

Introduction

This part of ISO 12217 enables the determination of limiting environmental conditions for which an

individual boat has been designed.

It enables the boat to be assigned to a design category appropriate to its design and maximum load.

The design categories used align with those in the Recreational Craft Directive of the European Union,

EU Directive 2013/53/EU.
