11、ion) 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 r
12、epresented on that committee. International organisations, 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
13、 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 Internat
14、ional 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.

17、tion The amendments of 2000 to Chapter II-2 of the 1974 International Convention for the Safety of Life at Sea (SOLAS), which entered into force 1 July 2002, made the carriage of emergency escape breathing devices (EEBD) mandatory on SOLAS ships. SOLAS and the related mandatory International Code fo
18、r Fire Safety Systems (FSS Code) prescribe basic performance requirements for EEBD. This part of ISO 23269 provides more detailed requirements to ensure an adequate level of safety for users of these devices.

19、Emergency escape breathing devices (EEBD) for shipboard use 1 Scope This part of ISO 23269 provides performance specifications for emergency escape breathing devices (EEBD) required by regulation in Part D of chapter II-2 of the 1974 International Convention for the Safety of Life at Sea (SOLAS), as
20、 amended in 2000, and chapter 3 of the IMO International Code for Fire Safety Systems (FSS Code). These devices are intended to supply air or oxygen needed to escape from accommodation and machinery spaces with a hazardous atmosphere. They are not intended for use in fighting fires, entering oxygen-
21、deficient voids or tanks, or to be worn by fire-fighters. 2 Normative references The following referenced documents are indispensable for the application of this document.

Hoods and facepieces shall be constructed of flame resistant materials and include a clear window for viewing. 4.1.3 The EEBD shall be designed so that there are no protruding parts or sharp edges
30、 likely to be caught on projections in narrow passages or that may hurt the wearer. 4.1.4 The EEBD shall be designed to ensure its full function in any orientation of the EEBD. 4.1.5 If the EEBD is equipped with a compressed air/gas cylinder, it shall be equipped with a reliable and continuous means
31、 to show that the cylinder is fully charged and ready for use, without the necessity of activating the EEBD. 4.1.6 The EEBD shall be capable of being carried hands-free. 4.1.7 A pressure indicator incorporating a suitable blow-out release shall be provided, such that in the event of an explosion or
32、fracture of the pressure indicator, the release shall be away from the wearer. The blow-out release shall be protected from dirt and mechanical damages.
