Overview
ISO 5700:2013 - "Tractors for agriculture and forestry - Roll‑over protective structures - Static test method and acceptance conditions" defines a standardized static test program and acceptance criteria for roll‑over protective structures (ROPS) used on wheeled or tracked tractors. The standard applies to tractors with at least two axles (pneumatic tyres) or tracks, an unballasted mass ≥ 600 kg and rear wheel track width > 1 150 mm. It is not applicable where the mass ratio (maximum permissible mass / reference mass) exceeds 1.75.
Key technical topics and requirements
- Test methods
- Horizontal loading tests (rear, front and side) and static crushing tests to simulate overturn loads.
- Sequence of tests, including optional second longitudinal loading.
- Apparatus and setup
- Specifications for test fixtures and beams, test instrumentation and load application points.
- Preparation and reference positions
- Determination of the Seat Index Point (SIP), seat location and adjustment for testing.
- Definition and measurement of the clearance zone for normal and reversible driver positions.
- Acceptance conditions
- Performance criteria for permanent deflection, required resisting force, overload tests and additional conditions (e.g., cold‑temperature brittle fracture considerations).
- Components covered
- ROPS structure, attachment brackets, and related tractor parts that might be loaded during an overturn.
- Ancillary requirements
- Seatbelt anchorage performance, labelling, and content requirements for the test report.
- Extensions and administration
- Procedures for administrative and technical extension of test results to other tractor models.
- Normative and informative annexes
- Annex A: optional cold‑temperature fracture resistance requirements.
- Annex B: standardized test report template.
- Annex C: Maintenance Agency designation and harmonization with OECD Code 4.
Practical applications - who uses ISO 5700:2013
- Tractor manufacturers - design and validate ROPS (frames and cabs) to meet static strength and clearance requirements.
- Independent test laboratories - perform standardized static loading and crushing tests and issue test reports for certification.
- Certification bodies and regulators - assess compliance, approve labelling and grant type‑approvals or national certification.
- R&D and safety engineers - develop safer ROPS geometries and attachment systems, including cold‑temperature performance.
- Fleet owners and dealers - verify that retrofit or replacement ROPS meet required acceptance conditions.
