Introduction
Lighters, being flame-producing devices, can, as do all flame sources, present a potential hazard to
users. The safety specifications given in this document cannot eliminate all hazards, but are intended
to reduce potential hazards to users.
This document is intended to be revised periodically to consider flame height reduction for the various
technologies in line with technological progress.

adjustment allows if lower than 50 mm;
2) after a 5 s burn when set at maximum flame height.
ISO 9994:2018(E)

In the event of a shield becoming detached during the drop test, it can be re-attached, if this is
practicable, and the test continued.
5.5  Resistance to elevated temperature
5.5.1  Gas lighters, and fluid lighters with a sealed compartment filled with non-absorbed fuel, shall be
capable of withstanding a temperature of 65 °C for 4 h when tested in accordance with 6.9.
5.5.2  Lighters that meet this requirement, and that are able to be ignited in the intended manner, shall
after stabilization at a temperature of (23 ± 2) °C subsequently meet all the applicable requirements of
4.1 to 4.5, inclusive. Lighters that are not able to be ignited in the intended manner do not constitute a
failure.
5.6  Resistance to internal pressure
Gas lighters shall be capable of withstanding an internal pressure of twice the vapour pressure at 55 °C
of the fuel recommended by the manufacturer, when tested in accordance with 6.10.
5.7  Burning behaviour
5.7.1  The following types of lighter shall be capable of withstanding a burning time of 5 s when held
in a position such that the top of the wick, or burner valve orifice, is at an angle 45° ± 5° below the
horizontal (see Figure 4), without evidence of any burning or distortion of components so as to cause a
hazardous condition:
— adjustable gas lighters, with the flame height set at maximum
5.7.2  The following types of lighter shall be capable of withstanding a burning time of 10 s when held
in a position such that the top of the wick, or burner valve orifice, is at an angle of 45° ± 5° below the
horizontal (see Figure 4), without evidence of any burning or distortion of components so as to cause a
hazardous condition:
— fluid lighters;
— non-a
