The work of preparing International Standards is normally carri
9、ed 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 represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. I
10、SO collaborates 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 Internati
11、onal Standards. 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 el
12、ements 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 23269-3 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 1, Lifesaving and fire protection. ISO 23269 consists o
13、f the 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: Self-contained breathing apparatus for shipboard firefighters Part 3: Self-contained breathing apparatus (safety equip

15、riers) developed by the International Maritime Organization require that self-contained breathing apparatus (safety equipment) be carried on board chemical tankers and gas carrier ships. However, these Codes do not technically specify the details of such apparatus; such a specification is necessary
16、to provide a sufficient safety level for users.

17、Scope This part of ISO 23269 provides performance specifications of the self-contained air-breathing apparatus (SCBA) (not using stored oxygen) required by the IMO IBC Code (for bulk chemicals) and the IMO IGC Code (for gas carriers) developed by the International Maritime Organization. The breathin
18、g apparatus manufactured in accordance with this part of ISO 23269 constitutes an element of the set of safety equipment which permits personnel to enter a gas-filled compartment and perform work there. The breathing apparatus is not intended for use in fighting fires or suitable for entry into flam

23、 Basic performance tests and requirements 6.1 General The apparatus shall comply with all of the requirements of Clause 6 of ISO 23269-2:, except: a) 6.9.2 on flammability; b) 6.9.3 on resistance to radiant heat. In addition, the apparatus shall be subjected to the tests specified in 6.2 to 6.4. 6.2
24、 Chemical permeation resistance test 6.2.1 The breathing apparatus shall be tested using the principles set forth in ISO 15537. Factors such as the intended user population, critical dimensions of the breathing apparatus, protective clothing likely to be worn with the breathing apparatus, and critic
25、al tasks the wearer might perform shall be determined, and shall be described in the test report. 6.2.2 A solution of water and non-toxic, coloured dye shall be prepared and placed in a spray bottle. The coloured water shall provide sufficient contrast to indicate penetration of the facepiece of the
26、 breathing apparatus by visual inspection of the interior. 6.2.3 The test subjects shall individually don a breathing apparatus along with the protective clothing and other related safety equipment. With the test subjects standing upright, the coloured water shall be sprayed on the top and the sides
27、 of the breathing apparatus. After spraying the water, there shall be no permeation of water through the facepiece of the breathing device. 6.3 Chemical resistance test of the eyepiece and transparent materials Apply the following solvents, one at a time using a suitable applicator, to the eyepiece
28、or any transparent part: a) trichloroethylene; b) benzene; c) solvent naphtha; d) methanol; e) kerosene. 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 min, whichever occur
29、s first. After exposure, the test specimen shall be assessed by visual inspection. No dissolution or deterioration to the extent that the test specimen becomes unusable should be observed, e.g. no holes, leaks, fogging, or hazing are formed.
