4 Functional requirements
4.1 Flame generation
In order to minimize the possibility of inadvertent ignition, or sell-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).
4.2 Flame heights
NOTE Maximum flame heights specified in this International Standard, for both posimixing burner lighters and premixing burner lighters, will be reconsidered perio&ally with a view to gradual reduction in line with technological progress.
4.2.1 Non-adjustable lighters
4.2.1.1 Non-adjustable fluid lighters shall not be capable of producing a flame height greater than 120mm when tested in accordance with 6.2.
4.2.12 Non-adjustable, postmixing and premixing burner li9hters shall not be capable of producing a flame height greater than 50 mm when tested in accordance with 6.2.
4.2.2 Adjustable lighters
4.2.2.1 For adjustable lighters as defined in 3.8, the maximum flame height that a user will obtain under different conditions of use shall comply with the following requirements when tested in accordance with 6.2.
4.2.2.2 Adjustable (refillable or non-refillable) postmixing burner lighters shall have the flame height adjusted by the manufacturer in such a manner that the lighter, when first ignited by the user — without changing the adjustment — will not produce a flame height greater than 100 mm.
4.2.2.3 Adjustable refillable postmixing burner lighters shall not be capable of producing a flame height greater than 120 mm when deliberately adjusted by the user to the manufacturer’s design limit for maximum flame height.
4.2.2.4 Adjustable non-refillable postmixing burner lighters shall not be capable of producing a flame height greater than 100 mm when deliberately adjusted by the user to the manufacturer’s design limit for maximum flame height.BS EN ISO 9994 pdf download.
