ISO 2009 – 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 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 15371 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 1, Lifesaving and fire protection. This second edition cancels and replaces the first edition (ISO 15371:2000). Clause 5 has been technically revised along with minor editorial corrections throughout this International Standard. www.bzfxw.com BS ISO 15371:2009 ISO 15371:2009(E) © ISO 2009 – All rights reserved v Introduction While this International Standard provides the marine industry with a means for evaluating the effectiveness of fire-extinguishing systems for a variety of grease-laden cooking appliances that may be found in a galley, it is also referenced by the International Maritime Organization (IMO) International Convention for the Safety of Life at Sea (SOLAS), 1974, as amended, and provides organizations who are party to SOLAS with a means of ensuring conformance of deep-fat cooking equipment with the fire suppression requirements prescribed in SOLAS. www.bzfxw.com BS ISO 15371:2009 www.bzfxw.com BS ISO 15371:2009 INTERNATIONAL STANDARD ISO 15371:2009(E) © ISO 2009 – All rights reserved 1 Ships and marine technology — Fire-extinguishing systems for protection of galley cooking equipment 1 Scope This International Standard applies to the design, testing, and operation of pre-engineered fire extinguishing systems to protect the galley hoods, ducts, fryers and other grease-laden appliances. Pre-engineered fire-extinguishing system units are also required to comply with requirements for the construction and components performance as applicable to specific types, designs, sizes and arrangements. This International Standard also provides minimum requirements for the testing and evaluation of components. A product that contains features, characteristics, components, materials or systems that are new or different from those covered by the requirements in this International Standard and that involve a risk of fire, electric shock, or injury to persons, shall be evaluated using the appropriate additional component and end-product testing. NOTE Only deep-fat cooking equipment, among the types of galley cooking equipment covered by this International Standard, are required by SOLAS chapter II-2 Regulation 10.6.4 to have fixed fire-extinguishing systems. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 auxiliary equipment equipment used in conjunction with the extinguishing system EXAMPLE Auxiliary equipment can be used to shut down power, fuel or ventilation to the hazard area being protected or to initiate alarm or signalling devices. 2.2 cooking appliance cooking device that has, or is capable of having, a surface of liquid grease or one in which cooking with grease is involved EXAMPLE Deep fat fryer, griddle, range, chain-broiler, electric char-broiler, charcoal broiler, mesquite broiler, gas radiant char broiler, wok, tilt skillet/braising pan and similar appliances.
