component strength.
4.5 Brake control forces
4.5.1 The control forces to meet the required brake performances for the systems, as specified in 6.2
and either 6.3.1 or 6.3.2, shall not exceed the values given in 4.5.2 to 4.5.6 and summarized in Table 1. NOTEļ¼ŒOther types of brake actuations are possible.
4.5.2 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.
4.5.3 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 while travelling shall not be greater than 200 N.
4.5.4 For parking brakes applied by means of a hand lever, the required brake performance shall be attained when a force not greater than 300 N is applied to the hand lever at the gripping point.
4.5.5 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 handgrip at the gripping point.
4.5.6 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.
4.6 Brake component strength
4.6.1 The strength of brake components shall not be lower than the values given in 4.6.2 to 4.6.6 and summarized in Table 1.
4.6.2 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.
4.6.3 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.
4.6.4 For trucks having a hand lever to apply the parking brake(s), the system shall be capable of withstanding a force of at least 600 N applied at the gripping point of the lever, without any failure, cracking or deformation which affects the brake performance or function.
4.6.5 For trucks having a handgrip which is squeezed to apply the service brake(s), the system shall be capable of withstanding a force of at least 300 N applied to the handgrip, without any failure, cracking or deformation which affects the brake performance or function.
4.6.6 For trucks having a tiller which is depressed or released to apply the service or parking brake(s), the system and associated mechanical stops shall be capable of withstanding a force of at least 900 N applied at the midpoint of the handgrip, without any failure, cracking or deformation which affects the brake performance or function.ISO 6292 pdf download.
