Adjustable premixing burner lighters shall have the flame height adjusted by the manufacturer in such a manner that the lighter, when first ignited by the user一without changing the adjustment一will not produce a flame height greater than 60 mm.
Adjustable premixing burner lighters shall not be capable of producing a flame height greater than 75 mm when deliberately adjusted by the user to the manufacturer’s design limit for maximum flame height.
Adjustable postmixing and premixing burner lighters shall not be capable of producing a flame height greater than 50 mm when set at the lowest possible flame height.
Automatically adjusting pipe lighters shall not be capable, in any position, of producing a flame height greater than 100 mm.
Adjustable lighters as defined in 3.8 shall require a deliberate action on the part of the user either to 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.
On lighters whose adjusting mechanisms conform to 4.3.3 and 4.3.4, the direction of movement shall be permanently imprinted or engraved on the lighter in the vicinity of the adjusting mechanism and readily visible and understandable.
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.
Components of fluid lighters as defined in 3.2 that come into contact with the fuel recommended by the manufacturer shall not, after extended contact with that fuel, deteriorate so as to cause the lighter to fail any of the criteria contained in this specification, when tested in accordance with 6.5.
Components of gas lighters as defined in 3.3 that come into contact with the fuel recommended by the manufacturer shall not deteriorate after exposure to the fuel, so as to cause the lighter to fail any of the criteria contained in this specification or allow gas escape exceeding 15 mg/min, when tested in accordance with 6.5.BS EN ISO 9994 pdf free.
