4.2.4 Adjustable postmixing burner utility lighters
Adjustable postmixing burner utility lighters, as defined in 3.7 and 3.18, shall not be capable of producing a
flame height greater than 150 mm when the flame is directed vertically upward, when deliberately adjusted
by the user to the manufacturer’s design limit for maximum flame height and when tested in accordance
with 8.2.
4.2.5 Adjustable premixing burner utility lighters
Adjustable premixing burner utility lighters, as defined in 3.7 and 3.17, shall not be capable of producing a
flame height greater than 75 mm when the flame is directed vertically upward, when deliberately adjusted
by the user to the manufacturer’s design limit for maximum flame height and when tested in accordance
with 8.2.
4.2.6 Adjustable postmixing burner utility lighters (flame height on first ignition)
Adjustable postmixing burner utility lighters, as defined in 3.7 and 3.18, shall have the flame height adjusted
by the manufacturer in such a manner that the utility lighter, when first ignited by the user without changing
the adjustment, will not produce a flame height in excess of 100 mm when the flame is directed vertically
upward and when tested in accordance with 8.2.
4.2.7 Adjustable premixing burner utility lighters (flame height on first ignition)
Adjustable premixing burner utility lighters, as defined in 3.7 and 3.17, shall have the flame height adjusted
by the manufacturer in such a manner that the utility lighter, when first ignited by the user without changing
the adjustment, will not produce a flame height in excess of 60 mm when the flame is directed vertically
upward and when tested in accordance with 8.2.
4.2.8 Adjustable postmixing burner utility lighters (flame height at lowest setting)
Adjustable postmixing burner utility lighters, as defined in 3.7 and 3.18, shall be capable of producing a
flame not in excess of 75 mm with the flame directed vertically upward, when set at the lowest possible
flame height and tested in accordance with 8.2.
4.2.9 Adjustable premixing burner utility lighters (flame height at lowest setting)
Adjustable premixing burner utility lighters, as defined in 3.7 and 3.17, shall be capable of producing a flame
not in excess of 50 mm with the flame directed vertically upward, when set at the lowest possible flame
height and tested in accordance with 8.2.
4.2.10 Dual flame type utility lighters

shall conform to the corresponding requirement for that type of flame provided in 4.2.1 to 4.2.9.
4.2.11 Multiple flame type utility lighters
Multiple flame type utility lighters for each flame of a multiple flame type utility lighter, the flame shall
conform to the corresponding requirement for that type of flame provided in 4.2.1 to 4.2.9.

4.3 Flame-height adjustment
4.3.1 Adjustable utility lighters shall require a deliberate action on the part of the user either to decrease
or to increase the flame height when the utility lighter is used in the normal fashion.
4.3.2 If flame-height adjustment features protrude from the body of the utility lighter, it shall require a
minimum actuating force of 1 N applied over the entire range of adjustment in a tangential direction (see
Figure 2 for an example of test equipment).
Figure 2 — Block diagram showing a typical example of test equipment for measuring the flame-
height adjustment feature actuating force
4.3.3 Adjustable utility lighters having rotary movement flame-height adjustment features approximately
at right angles to the flame shall perform as follows.
a) When the flame-height adjustment feature of the utility lighter is held so the flame is oriented vertically
upward, and the user is facing the flame-height adjustment feature, moving the actuator to the left shall
produce a decrease in flame height.
b) Adjustable utility lighters requiring motion of the flame-height adjustment feature approximately
parallel to the flame axis shall decrease or increase the flame height according to the direction of the
movement.
c) When the flame control actuator is at the bottom of the utility lighter, and the utility lighter is held so
that the user is facing the actuator, a clockwise movement shall produce a decrease in flame height.
Adjustable utility lighters shall indicate the direction of movement to produce a higher or lower flame height.
On utility lighters, the direction of movement shall be permanently imprinted or engraved on the utility
lighter. Such information shall be placed on the utility lighter in the vicinity of the flame-height adjustment
feature and be readily visible and understandable.

7.5 Refilling instructions
Refillable utility lighters shall be accompanied by specific instructions and warnings as to the correct
procedure to accomplish the refill operation by inserting a prefilled fuel reservoir or by refilling with an
external container. These instructions shall indicate the fuel recommended by the manufacturer and include
the appropriate information to ensure the proper mating between the external container or the prefilled fuel
reservoir and the utility lighter.
8 Test methods
8.1 Test specimens and test sequencing
8.1.1 Test specimens
Unless otherwise specified in the test methods described hereafter, test specimens shall consist of new,
complete, normally fuelled utility lighters and shall be initially free of mechanical damage.
Refillable utility lighters that are sold empty of fuel shall be fuelled according to the method prescribed by the
manufacturer before starting any test.
8.1.2 Test sequencing
The test sequencing shall be carried out in accordance with Annex AAnnex A.
Upon receipt and before any testing commences, all samples shall be weighed to an accuracy of 0,1 mg. The
heaviest utility lighter shall be tested according to 8.128.12.
8.2 Flame height measurement
8.2.1 General
The purpose of this procedure is to define the method of measurement of utility lighter flame height.
8.2.2 Apparatus
8.2.2.1 8.2.2.1 Vertically supported non-flammable board, marked horizontally in 5 mm
increments. The board shall be fitted with a standoff at the base point that positions the utility lighter at least
25 mm from the board.
8.2.2.2 8.2.2.2 Draught-free chamber, constructed from non-flammable materials.
8.2.2.3 8.2.2.3 Stopwatch/metronome/timer or any alternative device, capable of
emitting an audible and/or visual signal at 1 s interval.
8.2.3 Test specimens
The test specimens shall consist of utility lighters that are fuelled in accordance with the manufacturer’s
specifications.
8.2.4 Procedure
8.2.4.1 8.2.4.1 Tests shall be conducted inside the draught-free chamber.
8.2.4.2 8.2.4.2 Standardize the utility lighter flame height measurements by stabilizing all
utility lighters at (23 ± 2) °C for at least 10 h prior to each flame height measurement.
8.2.4.3 8.2.4.3 Place the utility lighter against the standoff so that the flame will be directed
vertically upward.
8.2.4.4 8.2.4.4 Ignite the utility lighter, allow the flame to stabilize for approximately 1 s, then
during the next 5 s of the burn measured with a stopwatch/metronome/timer or any alternative device,
determine the flame height by naked eye, as defined in 3.33.3,, to the nearest 5 mm by determining where the
tip of the visible flame registers in relation to the scribed marks on the board
