ISO/DIS 9994-2015 pdf free.Lighters – Safety specifications.
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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.

Note 1 to entry: Lighters are specifically not intended for use as candles or as flashlights, or for other uses requiring an extended bum time.
3.2 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.
4.1 Flame generation
In order to minimize the possibility of inadvertent ignition, or slf-ignition, lighters shall require a deliberate manual operation to produce a flame. This operation shall conform to at least one of the following requirements:
a) positive action on the part of the user shall be required to generate and maintain a flame;
b) two or more independent actions by the user shall be required to generate a flame;
c) an actuating force equal to, or greater than, 15 N shall be required to generate a flame (see Figure 1 or Figure 2).ISO/DIS 9994 pdf free download.
