    22、ational 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 b

    23、een 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 sta

    24、ndardization. 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 l

    25、east 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 11812 was pre

    26、pared by Technical Committee ISO/TC 188, Small craft. Annexes B, C, D and E form a normative part of this International Standard. Annex A is for information only.

    27、vi ISO 2001 All rights reserved Introduction The compliance to this International Standard may not be required to show that a boat fulfils the essential safety requirements of the Directive 94/25/EC, but it may be required by ISO 12217.

    28、proved subscription and freemailing clients of the SABS.INTERNATIONAL STANDARD ISO 11812:2001(E) ISO 2001 All rights reserved 1Small craft Watertight cockpits and quick-draining cockpits 1 Scope This International Standard specifies requirements for cockpits and recesses to be designated either as “

    29、watertight” or as “quick-draining” on small craft of hull length up to 24 m. It does not set requirements for the size and shape of a cockpit or recess, nor when or where it shall be used. It only considers draining by gravity, and not by pumping or other methods. NOTE 1 The term “quick-draining coc

    30、kpit” has been chosen to differentiate from the common understanding of “self-draining cockpit” where water may be drained overboard in certain conditions, but without specified draining speed, height of bottom or sill, etc. NOTE 2 Examples of single-plane cockpit bottoms are given in informative an

    31、nex A. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to

    32、 agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain re

    37、 to be suitable NOTE The following design categories apply: A: Ocean: Designed for extended voyages where conditions may exceed wind force 8 (Beaufort scale) and significant wave heights of 4 m and above, and vessels largely self-sufficient; but excluding abnormal conditions such as hurricanes. B: O

    38、ffshore: Designed for offshore voyages where conditions up to and including wind force 8 and significant wave heights up to and including 4 m may be experienced; C: Inshore: Designed for voyages in coastal waters, large bays, estuaries, lakes and rivers where conditions up to and including wind forc

    39、e 6 and significant wave heights up to and including 2 m may be experienced; D: Sheltered waters: Designed for voyages in close coastal waters, small bays, lakes, rivers and canals where conditions up to and including wind force 4 and maximum wave heights up to and including 0,3 m may be experienced

    40、. 3.2 length of hull L Hlength of the hull according to ISO 8666 NOTE Length of hull is expressed in metres. 3.3 maximum beam B max overall beam of monohull or multihull craft according to ISO 8666 NOTE Maximum beam is expressed in metres. 3.4 waterline WL waterline in the fully loaded ready-for-use

    41、 condition 3.5 freeboard amidships F M freeboard at mid-waterline in fully loaded ready-for-use condition according to ISO 8666 3.6 sailing boat boat designed to use sails as its primary means of propulsion, as defined in ISO 12217-2 3.7 non-sailing boat boat not designed to use sails as primary mea

    42、ns of propulsion, as defined in ISO 12217-1 3.8 cockpit and recess any area that may retain water, however briefly, due to rain, waves, boat heeling, etc. SANS 11812:2008This standard may only be used and printed by approved subscription and freemailing clients of the SABS.ISO 11812:2001(E) ISO 2001

    43、 All rights reserved 3NOTE Cockpits are normally designed for accommodation of people but, for the purpose of this International Standard, the term “cockpit” will be used either for a proper cockpit or for any recess. This means that bulwarks may create a large cockpit, open boats may effectively co

    44、mprise a cockpit which includes nearly all the boat, cockpit(s) may be situated anywhere in the boat, and a cockpit may open aft to the sea. 3.9 watertight cockpit or recess cockpit or recess which satisfies the requirements of this International Standard for watertightness and sill heights, but not

    45、 those for drainage 3.10 quick-draining cockpit or recess cockpit with characteristics and draining capacity which fulfil all the requirements of this International Standard for one or several design categories NOTE According to its characteristics, a cockpit may be considered quick-draining for one

    46、 design category, but maybe not for a higher category. 3.11 cockpit sole essentially horizontal surface(s) of the cockpit on which people normally stand 3.12 cockpit bottom lowest surface of the cockpit sole where water collects before being drained NOTE 1 Devices raising the standing level(s) from

    47、the rigid part of the cockpit sole, e.g. grating, stands, bridge decks, are not considered as part of the cockpit bottom. NOTE 2 The cockpit bottom is considered to comprise only one plane. A cockpit bottom with several levels is considered according to annex B. 3.13 bridge deck area just outside th

    48、e companionway opening and above the cockpit bottom, onto which people normally step before entering the accommodation 3.14 closing appliance device used to cover an opening in the cockpit, hull or superstructures EXAMPLE Hatch, window, door, engine cover, etc. 3.15 cockpit water-retention height h

    49、C height of the water contained in the cockpit measured between the cockpit bottom and the point of overflow outboard, the boat being upright, at rest and fully loaded NOTE 1 This height corresponds to the lowest point where the overflow area, expressed in square metres, is 0,005 L HB max , and is usually the lowest point of the cockpit coaming. NOTE 2 For assessing h C , every closing appliance, including the companionway door(s) is assumed to be closed. SANS 11812:2008This standard may
