Ships and marine technology — Pyrotechnic life-saving appliances — Testing, inspection and marking of production units

ISO 15736:2006 specifies production tests and inspections, conformity assessment procedures, and marking requirements for life-saving appliances that utilize pyrotechnic devices in functioning. Specifically, it applies to products which have been evaluated and tested in accordance with the IMO Recommendation on testing of life-saving appliances, and type approved by maritime administrations to the requirements of the IMO Life-Saving Appliance (LSA) Code for use on ships subject to the requirements of the 1974 Safety of Life at Sea Convention (as amended). The basic principles may be considered suitable for pyrotechnic life-saving appliances manufactured to other than the IMO requirements, however ISO 15736:2006 applies directly only to products for which it contains specific 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 15736 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee

Introduction

This International Standard is intended for use in conjunction with the International Maritime Organization’s

(IMO) Life-Saving Appliance (LSA) Code and related IMO instruments to assess the conformity of production

pyrotechnic life-saving appliances with IMO requirements. Some of the provisions of this standard exceed

IMO requirements in that the IMO Recommendation on testing of life-saving appliances (IMO Resolution

A.689(17), as amended through Resolution MSC.81(70)) does not specifically address sampling, testing,

inspection, and marking of production units of pyrotechnic life-saving appliances. It is believed to accurately

reflect current best practices among manufacturers of approved pyrotechnic life-saving appliances.

INTERNATIONAL STANDARD ISO 15736:2006(E)
Ships and marine technology — Pyrotechnic life-saving
appliances — Testing, inspection and marking of production
units
1 Scope

This International Standard specifies production tests, inspections, conformity assessment procedures and

marking requirements for life-saving appliances that utilize pyrotechnic devices in functioning. Specifically, it

applies to products which have been evaluated and tested in accordance with the International Maritime

Organization (IMO) Recommendation on testing of life-saving appliances, and type approved by maritime

administrations to the requirements of the IMO Life-Saving Appliance (LSA) Code for use on ships subject to

the requirements of the 1974 Safety of Life at Sea Convention (as amended). The basic principles may be

considered suitable for pyrotechnic life-saving appliances manufactured to other than the IMO requirements,

however this International Standard applies directly only to products for which it contains specific requirements.

This International Standard does not affect the requirement in part 2, section 4 of the IMO Recommendation

on testing of life-saving appliances to periodically repeat full prototype testing of pyrotechnic life-saving

appliances. However, compliance with this International Standard may be taken into account by

administrations in prescribing the frequency of such tests.
2 Normative reference(s)

The following referenced documents are indispensable for the application of this document. For dated

references, only the edition cited applies. For undated references, the latest edition of the referenced

document (including any amendments) applies.

---------------------- Page: 6 ----------------------
ISO 15736:2006(E)
3.3
burn time
emission time

period of time measured from when a distinct sustained flame (or smoke for smoke signals) is emitted until it

ceases
3.4
lot

unit of production which, as far as is practicable, consists of items of a single type, class, size and type of

composition, manufactured under substantially the same conditions, and at substantially the same time

4 General requirements
4.1 Manufacturing standards

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

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

materials and according to the same quality standards as the prototype samples tested for approval by a

maritime administration, and are suitable for the purpose for which they are intended.

NOTE 1 This clause is not intended to inhibit refinements of manufacturing processes that do not adversely affect the

end product.

NOTE 2 Compliance with a quality management system such as the ISO 9000 series is recommended.

4.1.1 Recommended production testing and inspection procedures constituting an effective manufacturing

quality control system are contained in Annex A. The procedures in Annex A are intended to address the

requirement in Part 2 of the IMO Recommendation on testing of life-saving appliances for statistically

adequate sampling of production lots. (The term “lot” as used in this International Standard has the same

meaning as “batch” as used in Part 2 of the IMO Recommendation on testing of life-saving appliances.)

4.2 Visual appearance and craftsmanship

Pyrotechnic life-saving appliances shall be free from imperfections of manufacture affecting their appearance

or that may affect their serviceability.
4.3 Markings

Each production item produced in accordance with the procedures in this International Standard shall be

clearly and indelibly marked by the manufacturer with the following information:
a) Item type or model identification;

b) Relevant functional information (altitude, burn time, candela rating, and others as appropriate);

c) “SOLAS 96” or “IMO LSA Code”;
d) “ISO 15736”;
e) Name of manufacturer;
f) Month and year of manufacture; and

g) Approval information (as specified by the approving maritime administration(s)).
