15、on) 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 re

16、presented 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. International Standards

17、are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Internati

18、onal Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 9650-2 was

19、prepared by Technical Committee ISO/TC 188, Small craft. ISO 9650 consists of the following parts, under the general title Small craft Inflatable liferafts: Part 1: Type I Part 2 : Type II Part 3 : Material BSISO96502:2005IS-0569 O2:(5002E) I SO 5002 All irthgs ersedevr vIntroduction This part of IS

20、O 9650 is intended for inflatable liferafts for small craft used for leisure activities. It does not apply to liferafts required for ships under the International Maritime Organisation (IMO) Safety Of Life At Sea (SOLAS) Convention. A liferaft manufactured and maintained in accordance with this part

21、 of ISO 9650 should provide: a reasonably safe refuge for a shipwrecked person awaiting rescue; a reasonable service lifetime, provided a user meets a manufacturers clearly specified recommendations on stowage and maintenance. Compliance with this part of ISO 9650 does not imply that a liferaft will

22、 be suitable in all circumstances. A liferaft which complies with this part of ISO 9650 must be constructed in such a manner that maintenance is as easy and straightforward as possible. A user must be responsible for selecting a liferaft appropriate to the intended circumstances of use. Manufacturer

23、s and vendors must inform potential purchasers of the properties of the product, including possible choices (e.g. different equipment packs), limits on normal usage, and recommendations on stowage and maintenance. The tests in this part of ISO 9650 have been designed to simulate reality as closely a

24、s possible. Compliance with a test does not guarantee similar performance in service. For example, compliance with the re-righting tests does not guarantee that a liferaft can be righted at sea by an exhausted person in any circumstances.

26、applicable on small craft of hull length up to 24 m; suitable for launching overboard from a height not exceeding 4 m; designed for voyages, where moderate conditions may be met in areas such as, but not limited to, coastal water, large bays, estuaries, lakes and rivers; with a high degree of self-s

27、ufficiency. Type I liferafts are specified in ISO 9650-1. 2 Normative references The following referenced documents are indispensable for the application of this document.

Further fittings may be included, provided the tests of Clause 6 are completed. 4.2 Temperature conditions Type II liferafts shall be designed to inflate correctly at an air temperature between 0 C and + 65 C. 5 Requirements 5.1 General requirem

35、ents Type II inflatable liferafts, serviced in accordance with the manufacturers instructions, shall provide an adequate protection against the risks incurred and shall satisfy the requirements described in the this part of ISO 9650.

38、 I SO 5002 All irthgs ersedevr5.2.1.2 Properties of the painter line The painter line shall be positioned at the entrance to the liferaft. The length of the painter line shall be at least 6 m. A coloured indication shall be visible at less than 1 m from the firing point. The painter line shall be ef

39、ficient and shall be easy to handle and to pull. The breaking load of the painter line, and of its attachment system to the liferaft, shall not be less than 7,5 kN. The painter-line attachment system shall be constructed so as to not damage the liferaft on failure of the attachment system. The paint

40、er line shall withstand weathering. 5.2.2 Inflation The liferaft shall inflate within the temperature ranges according to 4.2, during the course of the launching and temperature inflation tests conducted in accordance with 6.2 and 6.3. 5.2.2.1 Initial inflation system General The initial inflation s

41、ystem shall be actuated by a pull on the painter line, thereby allowing the release of a pressurised gas. All subsequent force exerted on the painter line shall act directly on the towing point, or any other point offering strength characteristics equivalent to the values required for the painter li

42、ne (see 5.2.1.2). This inflation system may be supplemented by an automatic inflation system, i.e. inflation without pulling on the painter line (e.g. hydrostatic pressure-sensitive automatic actuation). 5.2.2.2 Actuation device The inflation-system mechanism shall attain the fully open position by

43、exerting a pulling force on the painter line, not exceeding 150 N and with a travel not exceeding 200 mm. The operating device shall be made of corrosion-resistant material capable of withstanding, without damage, a painter load of 450 N. The operating cable assembly shall not cause any wear of the

44、fabric of the buoyancy chambers by abrasion. 5.2.2.3 Inflation gas 5.2.2.3.1 Type of gas The gas, or mixture of gases, used for inflating the liferafts shall be non-toxic, for example carbon dioxide. The type and quantity shall provide a sufficient rate of inflation to allow the complete system to m

45、eet the specified inflation performance requirements for the equipment in which it is installed. If the gas used is carbon dioxide, its moisture content shall be no more than 150 parts of water per million parts of gas by mass. 5.2.2.3.2 Quantity of gas The quantity of gas shall be sufficient for th

46、e liferaft to inflate and achieve working pressure under low temperatures, as required by 6.3.4. The quantity of gas in the cylinder shall be such that the internal pressure of the cylinder, at the temperature of + 65 C, does not exceed the hydraulic test pressure of the cylinder.

47、0569 O2:(5002E) I SO 5002 All irthgs ersedevr 55.2.2.4 Gas cylinder The gas cylinder shall conform to national or international regulations. It shall be corrosion-proof in accordance with the specifications of ISO 9650-3. For an inflation system, where a liquefied gas is used, the cylinder shall be

48、fitted with a corrosion-proof bursting disc in accordance with ISO 6718, or with an equivalent safety device to prevent bursting of the cylinder. The bursting disc or the safety device shall operate prior to the internal cylinder pressure reaching the hydraulic test pressure. 5.2.2.5 High-pressure h

49、ose assembly (if fitted) Where a high-pressure hose assembly is used to convey the gas from the cylinder to the buoyancy chamber, it shall meet the following conditions: a) there shall be no leaks or any sign of deterioration after having been subjected, during at least 1 min, to a hydraulic test in accordance with ISO 1402, under a pressure of 12,5 MPa for liquef
