AS ISO 6292:2015 Powered industrial trucks and tractors—Brake performance and component strength
4.6.1 For brakes applied by depressing a pedal, the required service brake performance and parking brake performance shall be attained with a pedal force not greater than 450 N.
4.6.2 For brakes applied by an upward movement of a brake pedal (releasing the brake pedal), the required service brake performance and parking brake performance specified shall be attained with the pedal fully released. The force required to release the brakes and to hold the pedal fully depressed whilst travelling shall not be greater than 200 N.
4.6.3 For parking brakes applied by means of a handlever, the required brake performance shall be attained when a force not greater than 300 N is applied to the handlever at the gripping point.
4.6.4 For service brakes applied by squeezing a handgrip, the required brake performance shall be attained when a force not greater than 150 N is applied to the handlever at the gripping point.
4.6.5 For brakes applied by means of a tiller which is biased, e.g. spring loaded, to the upright position (as on pedestrian controlled trucks), the required service brake performance shall be attained at the maximum depressed stroke position of the tiller when a force not greater than 150 N is applied at the mid-point of the handgrip.
4.7.1 For trucks having a downward movement of a brake pedal (depressing the brake pedal) to apply the service or parking brake(s), the system shall be capable of withstanding a brake pedal force of at least 1 200 N without any failure, cracking or deformation which affects the brake performance or function.
4.7.2 For trucks having an upward movement of a brake pedal (releasing the brake pedal) to apply the service or parking brake(s), the system shall be capable of withstanding a force of 200 % of the maximum possible setting of the spring which applies the brake(s), without any failure or cracking or any deformation which affects the brake performance or function.
The pedal when fully depressed, and its associated mechanical stop shall be capable of withstanding a force of 1 800 N applied at the centre of the brake pedal actuating surface without any failure, cracking or deformation which affects the brake performance or function.
