Ships and marine technology — Position-indicating lights for life-saving appliances — Testing, inspection and marking of production units

ISO 24408:2005 specifies production tests and inspections, and marking requirements for position-indicating lights used in conjunction with various items of life-saving equipment, including survival craft 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 International Convention for the Safety of Life at Sea, 1974 (as amended). The basic principles may also be considered suitable for position-indicating lights manufactured to other than the IMO requirements.

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 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 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 International 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 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.

ISO 24408 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee

SC 1, Lifesaving and fire protection.

Introduction

This International Standard 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 provisions 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 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 Standard specifies procedures that meet the above requirements; thus by following these,

manufacturers will be able to demonstrate compliance with the IMO recommendation.

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 craft interior

lights. Specifically, it applies to position-indicating lights which have been type approved by or on behalf of a

4 General
4.1 Manufacturing standards

4.1.1 Manufacturers shall have in place a manufacturing quality control system sufficient to ensure that series

production units are manufactured according to substantially the same production methods, from the same

materials and 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 quality 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 one week’s

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 week's production,

whichever is less.
4.2 Visual appearance and craftsmanship

Position-indicating lights 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 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) manufacturer’s name or trademark;

f) lot number, or other means of identifying the production lot 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 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 obtain approval, and shall not exceed the date of expiry of the battery

installed in it. In the case of a light with a replaceable battery, the battery shall be marked with a date of expiry,

and the unit markings shall include space for a user to mark the date of expiry of the battery when installed.

4.3.2.2 The date of expiry of a battery used in a position-indicating light shall not exceed 50 % of the service

life of the battery. The service life of the battery shall be as established by the battery manufacturer, taking the

following losses into account at ambient temperature:

a) testing, as recommended by the manufacturer or as required by the regulatory authority, whichever is the

more stringent;
b) self-discharge of the battery pack;
