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 3.
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 International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 15371 was prepared by Technical Committee ISO/TC 8, Ships and marine technology,
Subcommittee SC 1, Lifesaving and fire protection.
It is intended to supplement International Maritime Organization (IMO) requirements for fire testing galley deep-fat
cooking equipment on commercial ships complying with the 1974 Safety of Life At Sea Convention (SOLAS 74), as
amended.

INTERNATIONAL STANDARD ISO 15371:2000(E)
Ships and marine technology — Fire-extinguishing systems for
protection of galley deep-fat cooking equipment — Fire tests
1 Scope
1.1 This International Standard covers the performance during fire tests of pre-engineered fire-extinguishing
system units intended for the protection of galley deep-fat cooking equipment.
1.2 Pre-engineered fire-extinguishing system units are required to comply also with the requirements for
construction and performance as applicable to specific types, designs, sizes and arrangements, but all such
additional requirements which apply are not considered to be within the scope of these requirements for fire tests.
2 Terms and definitions
For the purposes of this International Standard, the following terms and definitions apply.
2.1
cooking grease
a vegetable shortening incorporating an antifoaming agent
2.2
cylinder/valve assembly
a container that incorporates a valve and that provides storage of the extinguishing agent and expellant gas until
the valve is actuated
NOTE For cartridge-operated units, this assembly includes the extinguishing-agent storage container and cartridge
mechanism.
2.3
deep-fat fryer
a commercially available electric cooking appliance in which cooking greases in depth are used
2.4
discharge nozzle
a device that is used to distribute the extinguishing agent over or into a specific area
2.5
discharge rate
the ratio of the quantity of extinguishing agent discharged from a nozzle to the discharge time measured to within
�1s,expressedinkg/s
2.6
discharge time
the time interval between the first appearance of extinguishing agent at the nozzle and the time at which the
discharge becomes predominantly gaseous or ceases
2.7
expellant gas
nitrogen air or other gas used to facilitate the discharge of the extinguishing agent

ISO 15371:2000(E)
2.8
extinguishing system unit
identified components that can be assembled into a system for the discharge of an extinguishing agent through
fixed piping and nozzles for the purpose of extinguishing fires
2.9
gas cartridge
a container that provides storage for an expellant gas only
2.10
manual means of actuation
a means of system actuation in which a system is discharged by manual means
2.11
multiple-vat deep-fat fryer
multiple electric fryers which are mechanically joined together
NOTE Each vat incorporates a separately controlled heating source.
2.12
operable pressure range
the pressure range corresponding to the pressures in the storage container at the specified minimum and
maximum temperatures for which the extinguishing system unit is intended to be operable
2.13
operational pressure
the pressure developed in a fully charged container conditioned at 21 °C for at least 24 h
2.14
pre-engineered system
a system that is tested in accordance with the limitations prescribed by the manufacturer for maximum and
minimum pipe lengths, accessories, number of fittings, number and types of nozzles, nozzle placement, types of
fire risk and the maximum dimensions and areas of the appliances to be protected
2.15
pressure vessel
pressure cylinder
a container that provides storage for the extinguishing agent and expellant gas
2.16
product
any fire-extinguishing system or any part thereof covered by these requirements unless specifically noted otherwise
2.17
split-vat deep-fat fryer
an electric fryer that incorporates a dividing partition which splits the fryer in sections
NOTE Each split-vat fryer incorporates a separately controlled heating source.

3 Extinguishing tests
3.1 General
3.1.1 An extinguishing system unit shall be tested with each type of deep-fat fryer with which it is intended to be
used. Specific test methods are contained in 3.2 and 3.3.
3.1.2 When fire tested, the extinguishing system unit shall cause the flame in the appliance to be completely
extinguished, and not permit re-ignition of the grease for 20 min or until the grease temperature is at least 34 °C
below its observed auto-ignition temperature, whichever is longer.
3.1.3 The fire test shall be conducted using a minimum discharge rate condition which is achieved by assembling
the extinguishing system using its maximum piping limitations with respect to number of fittings and size and length
of pipe in accordance with the manufacturer’s installation instructions.
3.1.4 The cylinder/valve assembly shall be filled to its rated capacity and the cylinder or gas cartridge
pressurized with the expellant gas to the normal operating pressure at 21 °C. The cylinder/valve assembly or gas
cartridge used for these tests sh
