12、tandardization) is a worldwide federation of national standards bodies(ISO member bodies). The work of preparing International Standards is normally carried out through ISOtechnical committees. Each member body interested in a subject for which a technical committee has beenestablished has the right
13、 to be represented on that committee. International organizations, governmental andnon-governmental, in liaison with ISO, also take part in the work. ISO collaboratesclosely with the InternationalElectrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Stand
14、ards 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 Standardsadopted by the technical committees are circulated to the member bodies for voting. Publication as anInterna
15、tional 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 patentrights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 23269-2 was
16、prepared by Technical Committee ISO/TC 8, Ships and marine technology, SubcommitteeSC 1, Lifesaving and fire protection.ISO 23269 consists of the following parts, under the general title Ships and marine technology Breathing apparatus for ships: Part 1: Emergency escape breathing devices (EEBD) for
17、shipboard use Part 2: Self-contained breathing apparatus for shipboard firefighters Part 3: Self-contained breathing apparatus (safety equipment) required by the IMO IBC and IGC Codes Part 4: Self-contained breathing apparatus for emergency escape required by the IMO IBC and IGC CodesISO 23269-2:201
18、1(E)iv ISO 2011 All rights reservedBS ISO 23269-2:2011IntroductionChapter II-2 of the International Convention of Safety of Life at Sea 1974 (SOLAS 74), as amended, requirescarriage by ships of breathing devices for firefighting purposes. The International Maritime Organization (IMO)International Co
19、de for Fire Safety Systems (FSS Code) specifies basic performance requirements for thesedevices. However, neither SOLAS 74 nor the FSS Code provides specifications in sufficient detail to ensure anadequate level of safety for users.This part of ISO 23269 provides detailed technical specifications fo
20、r shipboard breathing apparatus, tosupplement the basic requirements in the FSS Code. It takes into account existing European standards forfirefighters outfits for use by professional firefighters, such as EN 136 and EN 137. However, it also takes intoaccount that ships crews are generally not profe
21、ssional firefighters, and require a more user-friendly ensemblethan that specified in the EN standards.ISO 23269-2:2011(E) ISO 2011 All rights reserved vBS ISO 23269-2:2011BS ISO 23269-2:2011INTERNATIONAL STANDARD ISO 23269-2:2011(E)Ships and marine technology Breathing apparatus for ships Part 2:Se

23、y of Life at Sea (SOLAS 74), as amended, and chapter 3 of the International Code for FireSafety Systems (FSS Code).Although the breathing apparatus manufactured in accordance with this part of ISO 23269 are intended for usein fighting small to medium magnitude fires before the operation of any insta
24、lled fixed firefighting systems, theyare not intended or suitable for direct entry into flames.2 Normative referencesThe following referenced documents are indispensable for the application of this document.
