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 15029-2 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants.
ISO 15029 consists of the following parts, under the general title Petroleum and related products — Determination
of spray ignition characteristics of fire-resistant fluids:
⎯ Part 1: Spray flame persistence — Hollow-cone nozzle method
⎯ Part 2: Spray test — Stabilized flame heat release method
⎯ Part 3: Spray test — Large scale method

Petroleum and related products — Determination of spray ignition
characteristics of fire-resistant fluids — Part 2: Spray test -
Stabilized flame heat release method
WARNING — The use of this part of ISO 15029 may involve hazardous materials, operations and equipment.
This part of ISO 15029 does not purport to address all of the safety problems associated with its use. It is
the responsibility of the user of this part of ISO 15029 to establish appropriate safety and health practices
and determine the applicability of regulatory limitations prior to use.
1 Scope
This part of ISO 15029 specifies a method by which the fire hazards of pressurized sprays of liquid fire-resistant
fluids can be compared. Two sizes of propane flame are used to ignite and stabilize combustion of an air-atomized
release of fluid, and measurements related to the rate of heat release, length of flame and density of smoke are
taken to give quantitative information on the fire behaviour of the fluid. A scheme for classification of the fluids is
given, but no minimum performance requirements are specified.

For the purposes of this part of ISO 15029, the following terms and definitions apply.

stabilized flame
point at which the rate of energy release, flame length and other combustion properties, are steady as a function of

3.2

distance in millimetres from the vertical centre line of the gas burner to the furthest downstream point reached by
the visible flame

3.3
flame length index
function of the flame length and propane flow rate
3.4
ignitability factor
corrected value, to the nearest integer, of a function of heat release at a specific propane flow rate
3.5
smoke density
smoke density as defined in ISO 5659, as a function of smoke opacity in the flue pipe before and after introduction
of the test fluid
4 Principle
A pre-conditioned flux of the test fluid is delivered to a test chamber through a twin-fluid atomizer. Compressed air,
supplied to the nozzle at a controlled rate, is used to produce an atomized spray, which is exposed to a defined
flame of a gas burner present throughout the test. The gas flame acts to produce, by input of heat at a steady rate,
a stabilized spray flame (3.1), so that combustion properties, such as the rate of energy release and flame length,
are sufficiently steady over time to allow time-averaged values to be measured.
Temperatures are measured both at the entry to the combustion chamber and in the exhaust, with the burner
operating first without, and then with, release of the test fluid. The flame length (3.2) and smoke opacity of the
exhaust are also measured. Calculations of functions, such as flame length index (3.3), ignitability factor (3.4) and
smoke density (3.5) are made from these measurements. Sampling of the exhaust can enable the production rate
of other combustion products to be determined. A grading system for the performance of fire-resistant fluids is
developed from these determinations and calculations.

6.1.2 Combustion chamber
This shall be fabricated from steel sheet, 8 mm thick, of square cross-section with internal dimensions of
(2 000 ± 5) mm x (490 ± 5) mm. The inner and outer surfaces shall be painted with black heat-resistant paint. A
clear window of heat-resistant glass, 8,5 mm thick, shall be located in one side of the chamber. The glass shall be
(1 920 ± 10) mm x (525 ± 10) mm providing an open area of the window of (1 880 ± 10) mm x (480 ± 10) mm. The
window may be hinged to allow access to the chamber. All joints around the window shall be sealed during use.
The combustion chamber is illustrated in Figure 2.
6.1.3 Extraction system
The combustion chamber exit shall be connected to a contraction fabricated from steel sheet 1 mm thick, providing
a transition from the square to a circular cross-section with an internal diameter of 250 mm ± 4 mm. This
contraction is connected to a horizontal section of flue pipe 1 400 mm ± 10 mm in length, which in turn may be
connected to further exhaust ducting or clearing system that shall be designed to provide stable conditions in the
combustion chamber during a test.
The air flow through the chamber is produced by a jet pump mounted in the exhaust duct, producing an air velocity
of 1,4 m/s ± 0,1 m/s measured 50 mm ± 2 mm inside the combustion chamber inlet. The temperature of the air
entering the chamber shall be sufficiently constant within the range 10 °C to 25 °C, such that the temperature
variation over a period of 30 s shall not exceed 1 °C. The relative humidity of the air shall lie between 40 % and
80 %. The combustion chamber and exhaust system are illustrated in Figure 2.
6.1.4 Spray delivery system (see Figure 3)
6.1.4.1 Test fluid. The fluid shall be contained in a steel reservoir of minimum capacity 3 l, designed for an
internal pressure of 2,5 MPa at 20 °C. The flow of fluid from the reservoir is controlled by means of pressurized
nitrogen (5.2) supplied to the upper part of the reservoir, with a valve situated in the nitrogen supply pipe. Means
shall be provided to permit complete drainage of the system. The test fluid volume flow rate shall be controlled to
90 ml/min ± 0,5 ml/min at a temperature between 10 °C and 25 °C, by means of a valve, and measured

nylon and/or steel piping with an internal diameter of 7,5 mm ± 2,5 mm, rated at 2 MPa, and the flowmeter shall be
located 350 mm ± 150 mm downstream of the valve.

a steady flow rate of 1,92 Nm /h ± 0,05 Nm /h at a pressure of at least 0,2 MPa. The flow rate shall be measured
