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.
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.
International Standard ISO 14935 was prepared by Technical Committee
ISO/TC 28, Petroleum products and lubricants.

Petroleum and related products — Determination of wick
flame persistence of fire-resistant fluids
WARNING – The use of this International Standard may involve hazardous materials, operations and
equipment. This International Standard does not purport to address all of the safety problems associated
with its use. It is the responsibility of the user of this International Standard to establish appropriate safety
and health practices and determine the applicability of regulatory limitations prior to use.
1 Scope
This International Standard specifies a method for the assessment of the persistence of a flame applied to
the edge of a wick of non-flammable material immersed in fire-resistant fluid. The test relates to the bulk
behaviour of a fluid, which may provide pertinent information for safe transportation and storage. This test
does not ascertain the behaviour of a spray of fire-resistant fluid, for which ISO 15029 should be used. This
International Standard establishes one of two basic measures of fire-resistance, and may be called up in
1)
regulations governing their use under the Luxembourg Report . This International Standard does not apply
to certain water-containing fluids or emulsions that do not adhere to the test board.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of
this International Standard. At the time of publication, the editions indicated were valid. All standards are
subject to revision, and parties to agreements based on this International Standard are encouraged to

of IEC and ISO maintain registers of currently valid International Standards.

3 Definition
For the purposes of this International Standard, the following definition applies.
3.1 flame mean persistence: The largest average flame persistence time, in seconds, of five flame
exposures carried out under the conditions specified in this International Standard, each flame exposure
being the average of six determinations.
4 Principle
A length of non-flammable aluminosilicate board is soaked in the fluid being tested and placed in a
reservoir of the fluid with one edge exposed. A small flame is applied to the exposed edge of the board, and
the persistence, in seconds, of the flame after removal of the igniting flame is measured. A total of six
determinations is carried out for each of five different periods of flame application. The persistence of these
five different periods of application of the igniting flame are calculated, and the result is the largest of these
averages.
5 Reagents and materials
5.1 Propane, of commercial quality conforming to ISO 9162.
5.2 Cleaning materials, for cleaning the reservoir, consisting of solvents appropriate to the material
being tested.
6 Apparatus
6.1 Reservoir, constructed of suitable metal, approximately 200 mm in length, 25 mm in width and 20 mm
in depth. It shall be fitted with clips or clamping devices to hold the board (6.5) at either end, with a distance
between the inner edges of these clips of 180 mm ± 2 mm. Each clip or clamp shall have a reference mark at
30 mm ± 0,5 mm above the inside bottom of the reservoir. Figure 1 illustrates a suitable reservoir.
