The work of preparing International Standards is normally carried out

10、 through ISO technical committees. Each member body interested in a subject for which a technical committee has been 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 col

11、laborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards 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 S

12、tandards. 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 least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements

13、 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 23269-4 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 1, Lifesaving and fire protection. ISO 23269 consists of the

14、following parts, under the general title Ships and marine technology Breathing apparatus for ships: Part 1: Emergency escape breathing devices (EEBD) for shipboard use Part 2: Breathing apparatus for shipboard firefighters Part 3: Self-contained breathing apparatus (safety equipment) required by the

15、 IMO IBC and IGC Codes Part 4: Self-contained breathing apparatus for emergency escape required by the IMO IBC and IGC Codes ISO 23269-4:2010(E) ISO 2010 All rights reserved vIntroduction The International Bulk Chemical (IBC) Code and the International Gas Carrier (IGC) Code of the International Mar

16、itime Organization (IMO) require that self-contained breathing apparatus (SCBA) for emergency escape purposes be carried on board chemical tankers and gas carrier ships. However, these SCBA codes prescribe limited specifications, e.g. the prohibition of filter-type respiratory protection, a minimum

17、15-minute duration of service, and prohibition against the use of the apparatus in fire-fighting or cargo handling operations. A need was recognized for technical specifications of such apparatus to provide a sufficient level of safety for users and a consistent design and performance standard to be

18、 used on vessels subject to the IBC and IGC Codes. INTERNATIONAL STANDARD ISO 23269-4:2010(E) ISO 2010 All rights reserved 1Ships and marine technology Breathing apparatus for ships Part 4: Self-contained breathing apparatus for emergency escape required by the IMO IBC and IGC Codes 1 Scope This par

19、t of ISO 23269 provides performance specifications for the self-contained breathing apparatus (SCBA) required by paragraph 14.2.8.2 of the International Maritime Organization (IMO) International Bulk Chemical (IBC) Code and paragraph 14.4.2.2 of the IMO International Gas Carrier (IGC) Code for emerg

20、ency escape. Apparatus complying with this part of ISO 23269 are not intended for fire-fighting, cargo handling, or approach or entry into flames. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition

21、cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 23269-1:2008, Ships and marine technology Breathing apparatus for ships Part 1: Emergency escape breathing devices (EEBD) for shipboard use 3 Terms and definitions For the pur

22、poses of this document, the terms and definitions given in ISO 23269-1 apply. 4 General design requirements The apparatus shall comply with all of the requirements of Clause 4 of ISO 23269-1:2008. 5 Environmental tests The apparatus shall comply with all of the requirements of Clause 5 of ISO 23269-

23、1:2008. When conducting the temperature cycling test of 5.3 of ISO 23269-1:2008, the temperature gradient between the defined temperatures of minus 30C and plus 65C shall be less than 2C/min to prevent thermal shock. ISO 23269-4:2010(E) 2 ISO 2010 All rights reserved6 Basic performance tests and req

24、uirements 6.1 General The apparatus shall comply with all of the requirements of Clause 6 of ISO 23269-1:2008, except: a) the breathing time for the rated working duration in accordance with 6.1 of ISO 23269-1:2008 shall be 15 minutes, and b) the breathing time for overloading in accordance with 6.2

25、 of ISO 23269-1:2008 shall be 5 minutes. 6.2 Chemical resistance test of the eyepiece and transparent materials Apply the following solvents, one at a time using a suitable applicator, to the eyepiece or any transparent part: a) trichloroethylene, b) benzene, c) solvent naphtha, d) methanol, e) kero

26、sene. One droplet of each chemical shall be applied to the test specimen, so that the droplet does not rinse. Exposure time shall be until the droplet evaporates or a maximum of 15 minutes, whichever occurs first. After exposure, the test specimen shall be assessed by visual inspection. No dissoluti

27、on or deterioration to the extent that the test specimen becomes unusable should be observed, e.g. no holes, leaks, fogging, or hazing are formed. 6.3 Chemical resistance test of facepiece If an SCBA will be marked and marketed for emergency use with a specific cargo listed in the IBC or IGC Codes,

28、the facepiece shall be tested against the products to which it will be exposed. Immerse a facepiece in the chemical at a temperature of 22 2 C for 1 hour and hang in air of temperature 22 2 C and relative humidity 95% for 24 hours. There shall be no corrosion or crack to make the facepiece unusable.

29、 The test shall also be repeated for the liquids listed in Table 1. Table 1 Test liquids for chemical resistance test Test liquids Concentration Sulphuric acid solution 1% Nitric acid solution 1% Sodium hydroxide 1% 7 Additional tests and requirements 7.1 Donning test The apparatus shall be tested i
