BS EN ISO 9994-2015 pdf – 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. UL 1 4539, Standard for tests for sharpness of edges on equipment ISO 7941 , Method of test for petroleum and its products – Commercial propane and butane – Analysis by gas chromatography 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 Lighter manually operated flame-producing device, employing a petrochemical derivative as a fuel, normally used for deliberately igniting cigarettes, cigars and pipes, and which might foreseeably be used to ignite materials such as paper, wicks, candles and lanterns Note 1 to entry: Lighters are specifically not intended for use as candles or as flashlights, or for other uses requiring an extended burn 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
3.4 Postmixing Burner Lighter gas lighter in which fuel is supplied for combustion and air is supplied at the point of combustion 3.5 Premixing burner lighter gas lighter in which fuel and air are mixed before being supplied for combustion 3.6 Non-refillable (disposable) lighter lighter marketed with an integral supply of fuel and that is not intended to be refilled with fuel. 3.7 Refillable lighter lighter intended to be refuelled either by transferring fuel from an external container or by inserting a new prefilled fuel reservoir 3.8 Adjustable lighter lighter provided with a mechanism for the user to vary the flame height 3.9 Non-adjustable lighter lighter that is not provided with a user-accessible mechanism to adjust the flame height Note 1 to entry: The flame height is preset by the manufacturer. 3.10 Automatically adjusting pipe lighter lighter characterized by an automatic increase in flame height when tilted from an upright position, designed specifically for the purpose of lighting pipes 3.11 Self-extinguishing lighter lighter that, once ignited, requires continuous intentional and positive action to maintain a flame and that is subsequently extinguished by the termination of such positive action 3.12 Non-self-extinguishing lighter lighter that, once ignited, does not require intentional or positive action by the user to maintain a flame and requires a subsequent deliberate user action to extinguish the flame
3.17 Flaring variation of flame height from the steady-state flame condition 3.18 Sustained self-ignition propagation of a flame by other than deliberate manual operation, such as by dropping the lighter, so as to cause the ignition element to be activated and the flame to continue to burn 3.19 Spitting Sputtering flame phenomenon of a gas lighter wherein the escape of non-evaporated liquefied gas produces a shower of burning liquid droplets which separate from the main flame 3.20 Flame result of combustion of fuel that produces heat and often light which could be visible with the naked eye under normal or subdued lighting conditions 3.21 Ignite produce a flame with a lighter by activating the self-contained ignition and fuel release systems of that lighter in the intended manner 3.22 Dual flame type lighter lighter that employs a burner valve system(s) that produces more than one type of flame (premixing and postmixing), which could be produced independently and separately (one flame type at a time), or dependently and concurrently (multiple flame types at a time) 3.23 Multiple flame type lighter lighter that employs a burner valve system(s) that produces more than one flame of the same type of flame (premixing or postmixing), which could be produced independently and separately (one flame at a time), or dependently and concurrently (multiple flames at a time)
