EN ISO 16231-1:2013 - Overview

EN ISO 16231-1:2013 (Self-propelled agricultural machinery - Assessment of stability - Part 1: Principles) specifies principles for assessing the stability of ride‑on, self‑propelled agricultural machines with respect to the hazards of rollover and tip‑over. It sets out the risk‑assessment framework, selection of protective measures, verification approaches and the type of information for use (operator’s manual) manufacturers must provide. The standard applies to new machines (not to machines manufactured before publication) and excludes machines under 400 kg, machines covered by other machine‑specific rollover standards (e.g. agricultural tractors), road transport hazards, free‑fall events and rollovers caused by impact collisions.

Key topics and requirements

• Risk assessment: Identify whether rollover/tip‑over hazards exist considering intended use, operating/ground conditions (slopes), machine physical properties, machine limits and operator capabilities.
• Protective measures: If risk is significant, one or more of the following must be applied:
  • Design to ensure Static Overturning Angle (SOA) ≥ Required Static Stability Angle (RSSA) with a suitable safety factor;
  • Fit Self‑Protective Devices (SPD) (attachments that improve stability);
  • Implement Automatic Protective Systems (APS) that intervene (e.g., reduce speed or change configuration) when stability limits are approached;
  • Provide a deflection limiting volume through a Self‑Protective Structure (SPS) or a Roll‑Over Protective Structure (ROPS) and ensure a compatible operator restraint (seat belt) installed per ISO 3776.
• Verification: The standard references verification procedures (see its Table 1) for checking functional measures and inspection/test methods in relevant directions (forward, rearward, lateral).
• Information for use: Required content for the operator’s manual, including safe working practices and residual risks.

Applications and users

EN ISO 16231-1:2013 is intended for:

• Manufacturers of self‑propelled agricultural machinery to design and document machine stability measures and prepare operator manuals.
• Design and safety engineers performing stability risk assessments and selecting ROPS/APS/SPD solutions.
• Test laboratories and certification bodies verifying conformance and validating protective measures.
• Compliance officers applying EU Machinery Directive (2006/42/EC) requirements; Annex ZA links this standard to Essential Requirement 3.4.3 (note: compliance with Part 2 is also required for full presumption of conformity).

Related standards

• ISO 16231‑2 (Calculations and test procedures - under preparation / used with Part 1)
• ISO 3776‑1/2/3 (seat belts - anchorage location, strength, assemblies)
• ISO 4254‑1 (Agricultural machinery - General safety requirements)

Keywords: EN ISO 16231-1:2013, self-propelled agricultural machinery, stability assessment, rollover, tip-over, ROPS, APS, SPD, operator’s manual, machinery safety.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
