9、SO 2005 All rights reserved Foreword ISO (the International Organization for Standardization) 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 intereste
10、d 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 collaborates closely with the International Electrotechnical Com
11、mission (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 Standards. Draft International Standards adopted by the techni
12、cal 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 of this document may be the subject of patent rights. ISO sh
13、all not be held responsible for identifying any or all such patent rights. ISO 24408 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 1, Lifesaving and fire protection.ISO 24408:2005(E) ISO 2005 All rights reserved v Introduction This International Standard
14、is intended for use in conjunction with the International Maritime Organization (IMO) Life-Saving Appliances (LSA) Code, and related IMO instruments, to assess the conformity of the production of various types of approved position-indicating lights with the relevant IMO requirements. Some of the pro
15、visions of this International Standard exceed the IMO requirements, in that the IMO Recommendation on Testing of Life-Saving Appliances Resolution A.689(17), as amended through Res. MSC.81(70), does not provide any specific requirements for testing and inspection of production units. However, Part 2
16、 of that document does require manufacturers to institute a quality control procedure to ensure that life-saving appliances are produced to the same standard as the prototype approved by the maritime safety administration, and to keep records of any production tests carried out. This International S
17、tandard specifies procedures that meet the above requirements; thus by following these, manufacturers will be able to demonstrate compliance with the IMO recommendation vi INTERNATIONAL STANDARD ISO 24408:2005(E) ISO 2005 All rights reserved 1 Ships and marine technology Position-indicating lights f
18、or life-saving appliances Testing, inspection and marking of production units 1 Scope This International Standard specifies production tests and inspections, and marking requirements for position- indicating lights used in conjunction with various items of life-saving equipment, including survival c
19、raft interior lights. Specifically, it applies to position-indicating lights which have been type approved by or on behalf of a national maritime safety administration, to the requirements of the International Maritime Organization LSA Code, for use in ships subject to the requirements of the Intern
20、ational Convention for the Safety of Life at Sea (SOLAS), 1974 (as amended). The basic principles may also be considered suitable for position-indicating lights manufactured to other than the IMO requirements. 2 Normative references The following referenced documents are indispensable for the applic

25、 according to the same quality standards as the prototypes tested for approval by or on behalf of a national maritime safety administration. NOTE 1 Clause 4 is not intended to inhibit refinements of manufacturing processes, which do not adversely affect the end product. NOTE 2 Compliance with a qual
26、ity management system such as ISO 9001:2000 is recommended. 4.1.2 Recommended production testing and inspection procedures constituting an effective manufacturing quality control system are contained in Annex A. 4.1.3 The maximum number of production units in a production lot shall be 1 000 units or
27、 one weeks production, whichever is less. In the case that the manufacturing process/system is in accordance with ISO 9001:2000, the maximum production lot quantity may be raised to 5 000 units or one weeks production, whichever is less. 4.2 Visual appearance and craftsmanship Position-indicating li
28、ghts used as life-saving appliances shall be free from imperfections of manufacture that affect their appearance, or that may affect their serviceability. 4.3 Marking 4.3.1 General Each production unit shall be clearly and indelibly marked by the manufacturer with the following information: a) type
29、or model identification, including intended use; b) identification and relevant approval mark of approving administration(s), and any operational restrictions; c) date of manufacture; d) date of expiry; e) manufacturers name or trademark; f) lot number, or other means of identifying the production l
30、ot from which the unit was taken; g) clear operating instructions in word or diagram form; h) if the power source is a lithium battery, the words LITHIUM BATTERY in block capitals, followed by DO NOT INCINERATE / DO NOT RECHARGE / DO NOT TAMPER NOTE Lights containing lithium or other batteries that
31、have not undergone special testing for designation as “Non- Hazardous” may require additional special markings for transportation. 4.3.2 Marking of date of expiry 4.3.2.1 The date of expiry marked on the product shall be based on the service life demonstrated or documented by the manufacturer to obt
