NF EN ISO 12217-3

<p>This part of ISO 12217 specifies methods for evaluating the stability and buoyancy of intact (i.e. undamaged) boats. The flotation characteristics of craft vulnerable to swamping are also encompassed.</p> <p>The evaluation of stability and buoyancy properties using this part of ISO 12217 will enable the boat to be assigned to a design category (C or D) appropriate to its design and maximum load. </p> <p>This part of ISO 12217 is applicable to boats of hull length less than 6 m, whether propelled by human or mechanical power, except habitable sailing multihulls. Boats of hull length less than 6 m, which are fitted with a full deck and quick-draining cockpit(s) complying with ISO 11812, may alternatively be assessed using ISO 12217-1 or ISO 12217-2 (for non-sailing and sailing boats respectively), in which case higher design categories may be assigned.</p> <p>This part of ISO 12217 excludes</p> aquatic toys, canoes, kayaks, or other boats with a beam of less than 1,1 m, inflatable and rigid-inflatable boats up to 8 m covered by ISO 6185, personal watercraft covered by ISO 13590, hydrofoils and hovercraft when operating in the dynamically supported mode, and submersibles. <p>It does not include or evaluate the effects on stability of towing, fishing, dredging or lifting operations, which should be separately considered if appropriate.</p>

Le présent amendement remplace le contenu du paragraphe 6.3 "Essai de chargement désaxé" de la norme NF EN ISO 12217-3:2002.

<p>ISO 12217-3:2015 specifies methods for evaluating the stability and buoyancy of intact (i.e. undamaged) boats. The flotation characteristics of craft susceptible to swamping are also encompassed.</p> <p>The evaluation of stability and buoyancy properties using ISO 12217-3:2015 will enable the boat to be assigned to a design category (C or D) appropriate to its design and maximum load.</p> <p>ISO 12217-3:2015 is applicable to boats of hull length less than 6 m, whether propelled by human or mechanical power, except habitable sailing multihulls. Boats of hull length less than 6 m which are fitted with a full deck and quick-draining cockpit(s) complying with ISO 11812 may alternatively be assessed using ISO 12217‑1 or ISO 12217‑2 (for non-sailing and sailing boats, respectively), in which case higher design categories may be assigned.</p> <p>In relation to habitable multihulls, ISO 12217-3:2015 includes assessment of susceptibility to inversion, definition of viable means of escape and requirements for inverted flotation.</p> <p>ISO 12217-3:2015 excludes:</p> <p> inflatable and rigid-inflatable boats covered by ISO 6185, except for references made in ISO 6185 to specific clauses of ISO 12217;</p> <p> personal watercraft covered by ISO 13590 and other similar powered craft;</p> <p> aquatic toys;</p> <p> canoes and kayaks;</p> <p> gondolas and pedalos;</p> <p> sailing surfboards;</p> <p> surfboards, including powered surfboards;</p> <p> hydrofoils, foil stabilized boats and hovercraft when not operating in the displacement mode; and</p> <p> submersibles.</p> <p>NOTE Displacement mode means that the boat is only supported by hydrostatic forces.</p> <p>ISO 12217-3:2015 does not include or evaluate the effects on stability of towing, fishing, dredging or lifting operations, which need to be separately considered if appropriate.</p>
