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.
