ISO 6292:2020 pdf download.Powered industrial trucks and tractors – Brake performance and component strength.
Industrial trucks, generally reterred to as trucks, can satisty the braking system requirements ot ISO 6292 by complying with either the stopping distance requirements or the drawbar drag requirements. Based on the requirements for brakes of rubber-tyred earthmoving machinery (ISO 3450), the stopping distance as a measurement value has been established. The brake performance is limited by consideration of the load. For further reference as to how the measurement of stopping distance and measurement of brake reaction time were derived, see ISO/TR 29944.
1 Scope
ISO 6292 specifies performance, test methods, controls, control forces and component strength for brake systems fitted to the following, as defined in Iso 5053-1:
— powered industrial trucks of all capacities;
— towing and pushing tractors up to and including 66 750 N drawbar pull (hereafter referred to as industrial tractors);
— burden carriers; and
— industrial trucks handling freight containers.
Loss of electrical power and loss of any other form of power assistance is not covered by this document. Braking systems used in emergency situations (e.g. activating the emergency switch or control system shut down) are not covered in this document.
ISO 6292 only includes requirements for newly manufactured trucks.
4.1 Required brake systems
The truck shall have the following brake systems:
— a service brake system;
— a parking brake system.
4.2 Operating means
The service and parking brakes shall be operated by means of independent systems. Both braking systems may utilize the same brakes; i.e. brake shoes, brake drums and related actuating items. Independent brake systems are not required to be fitted to stand-on and pedestrian controlled trucks as defined in ISO 3691-1.
4.3 Service braking system
All trucks shall meet the service brake requirements for:
— stopping distance (6.3fl and heat fade test (6.5.2);
— drawbar drag test (6.3.2) and heat fade test (6.5.3); or
— alternative test procedure (6.3.3), e.g. calculation, and heat fade test simulation (6.5).
4.4 Parking braking system
The parking braking system shall meet the requirements of 62.
4.5 Brake control forces
4.5.1 The control forces to meet the required brake performances for the systems, as specified in 2 and either 6.3.1 or 6.32. shall not exceed the values given in 4.5.2 to 4.5.6 and summarized in Tab1eJ..
NOTE Other 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), therequired 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.
Iso 6292:2020(E)
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.ISO-6292-2020
