ISO 5010:2019 PDF

Overview

ISO 5010:2019 - Earth-moving machinery - Wheeled machines - Steering requirements - specifies steering system tests and performance criteria for evaluating the steering capability of ride-on wheeled earth-moving machinery (as defined in ISO 6165:2012). The standard applies to machines equipped with wheels, one or more drums, or crawler wheel assemblies and addresses mechanical, ergonomic, maintenance, control-system and travelling-function hazards under intended use and reasonably foreseeable misuse. Functional safety of steering systems is not covered. ISO 5010:2019 replaces the 2007 edition and expands the scope to include drum and crawler wheel assemblies and machines with maximum speeds less than 20 km/h.

Key technical topics and requirements

• Steering system definitions: manual, powered, primary and secondary steering systems; steering control elements (steering wheel, joystick, levers, pedals).
• Performance criteria and tests: standardized test procedures to evaluate steering capability, including:
  • Wheel circle test (outer wheel clearance diameter)
  • Steering tests for primary and secondary steering systems
  • Tests for machines with alternative steering control elements
• Machine and test specifications: requirements for machine setup, instrumentation and test-course layout to ensure repeatable results.
• Ergonomic requirements: limits on steering effort, accessibility and operator control layout to reduce operator fatigue and improve safety.
• Hazard coverage: mechanical hazards, ergonomic hazards, hazards related to maintenance, control systems and travelling functions.
• Deliverables: required content of the test report and information-for-use instructions (instruction handbook) for operators and service personnel.
• Applicability: not retroactive - does not apply to machines manufactured prior to publication.

Practical applications and who uses this standard

ISO 5010:2019 is used to:

• Guide earth-moving machinery manufacturers in designing, testing and documenting steering systems to meet recognized safety and performance criteria.
• Support product validation teams and test laboratories performing steering capability and compliance testing.
• Inform safety/regulatory bodies, market surveillance and purchasers evaluating machine safety and operability.
• Help service providers and maintenance teams understand steering-system hazards and test requirements for repair, commissioning or after-failure assessment.
• Provide employers and fleet managers with criteria for selecting machines with proven steering performance and ergonomic suitability.
