ISO 6292:2020

Overview - ISO 6292:2020 in brief

ISO 6292:2020 specifies brake performance, test methods and component strength for brake systems fitted to powered industrial trucks, industrial tractors (up to 66 750 N drawbar pull), burden carriers and container-handling trucks. The standard covers requirements for newly manufactured trucks and defines performance verification using stopping distance or drawbar-drag methods and mandatory heat‑fade evaluation. It does not cover loss of electrical power or other forms of power assistance, nor braking systems used only in emergency shutdown situations.

Key topics and technical requirements

• Scope and definitions: Applies to powered industrial trucks of all capacities and industrial tractors as defined in ISO 5053-1. Important terms include stopping distance, drawbar drag, service brake, parking brake and fade test.
• Required brake systems: Trucks must have a service braking system and a parking braking system (independent operating means unless exempted for stand-on/pedestrian-controlled trucks).
• Performance tests:
  • Stopping distance test (s0) - measures distance from driver actuation to complete stop.
  • Drawbar drag test - assesses steady-state braking force applied to ground at speed.
  • Heat fade test - now compulsory for service brakes across test methods to assess performance loss with temperature.
  • Alternative methods (e.g., calculation or simulation) are allowed with heat‑fade simulation.
• Brake control forces (maximums):
  • Pedal actuation: service/parking performance must be achieved with ≤ 450 N pedal force.
  • Hand lever (parking): ≤ 300 N at gripping point.
  • Handgrip squeeze (service): ≤ 150 N.
  • Tiller (biased type): ≤ 150 N at mid‑point of grip.
• Component strength requirements:
  • Pedal systems must withstand 1 200 N (depressing) and 1 800 N applied at the pedal actuating surface for stop strength.
  • Hand lever structures: withstand 600 N at grip.
  • Handgrip: withstand 300 N.
  • Upward‑applied pedal systems: withstand 200 % of max spring setting.
• Stored energy systems: Requirements for service‑brake recovery capacity and warnings for loss of stored energy.

Applications - who uses ISO 6292:2020

• Manufacturers of forklifts, industrial tractors, burden carriers and container-handling trucks for design validation and type approval.
• Test laboratories and certification bodies conducting brake performance and component strength tests.
• Safety and compliance engineers specifying braking requirements for new truck fleets.
• OEMs and suppliers of brakes, actuators and control systems to ensure ergonomic control forces and structural robustness.
