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.
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 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 9994 was prepared by Technical Committee ISO/TC 61, Plastics.
This third edition cancels and replaces the second edition (ISO 9994:1995). Other than editorial changes made for
purposes of clarification, and changes in format now required by ISO, there are a number of technical changes as
follows.
a) The maximum flame height for adjustable postmixing burner gas lighters has been reduced.
b) Requirements for premixing burner gas lighters have been added to the standard. This type of lighter is
sometimes referred to as a “catalytic” lighter.
c) In the elevated-temperature test, the temperature has been increased and the controlled water bath has been
deleted.
d) The direction for flame height adjustment is now required to be permanently imprinted or engraved on the
lighter.
e) In the fuel compatibility test and the elevated-temperature test, a lighter empty of fuel is considered a failure.
This International Standard reproduces the technical content of ASTM/ANSI F 400-97.
Annex A of this International Standard is for information only.

INTERNATIONAL STANDARD ISO 9994:2002(E)

Lighters — Safety specification
1 Scope
This International Standard establishes requirements for lighters to ensure a reasonable degree of safety for
normal use or reasonably foreseeable misuse of such lighters by users.
The safety specification given in this International Standard applies to all flame-producing products commonly
known as cigarette lighters, cigar lighters and pipe lighters. It does not apply to matches, nor does it apply to other
flame-producing products intended solely for igniting materials other than cigarettes, cigars, and pipes.
Lighters, being flame-producing devices, can, as do all flame sources, present a potential hazard to users. The
safety specification given in this International Standard cannot eliminate all hazards, but is intended to reduce
potential hazards to users.

For the purposes of this International Standard, the following terms and definitions apply.
2.1

manually operated flame-producing device, employing a petrochemical derivative as a fuel, normally used for
deliberately igniting cigarettes, cigars and pipes, and which may foreseeably be used to ignite materials such as
paper, wicks, candles and lanterns
NOTE Lighters are specifically not intended for use as candles or as flashlights, or for other uses requiring an extended
burn time.
2.2
fluid lighter
lighter, with an exposed wick, that employs as fuel liquid hydrocarbons such as hexane whose gauge vapour
pressure at 24 °C does not exceed 34,5 kPa
2.3

decrease or to increase the flame height when used in the normal manner. Adjustable lighters shall bear an
indication showing the direction of movement of the adjusting mechanism required to produce a higher or lower
flame.
3.3.2 On lighters whose adjusting mechanisms conform to 3.3.3 and 3.3.4, the direction of movement shall be
permanently imprinted or engraved on the lighter.
3.3.3 Gas lighters having rotary-movement flame-control actuators approximately at right-angles to the flame
shall perform as follows:
a) when the flame-control actuator is at the top of the lighter and the lighter is held so that the flame is oriented
vertically upward, and the user is facing the flame-control actuator, moving the actuator to the left shall
produce a decrease in flame height;
b) when the flame-control actuator is at the bottom of the lighter, and the lighter is held so that the user is facing
the actuator, a clockwise movement shall produce a decrease in flame height.
3.3.4 For gas lighters requiring movement of the flame-control actuator approximately parallel to the flame axis,
the flame height shall decrease or increase in accordance with the direction of the movement.
3.3.5 If the flame-control actuator protrudes from the body of the lighter, it shall require a minimum actuating

c) In the case of postmixing burner lighters that have shields, an additional 2 s afterburn (i.e. continuous burning)
is acceptable if the flame, during this additional 2 s period, does not extend above the shield.
d) Non-adjustable premixing burner lighters, at their permanently set flame heights, when tested in accordance
with 5.4, shall have any flame completely extinguished in no more than 5 s.

NOTE In the case of premixing burner gas lighters, the total afterburn time in this International Standard will be
reconsidered periodically with a view to gradual reduction in line with technological progress.
