For many years, EN 1525 was the European standard for AGVs. ISO 3691-4 officially succeeded it to address modern technological advancements like AMRs. EN 1525 (Old Standard) ISO 3691-4 (Current Standard) Focused primarily on traditional tracked AGVs Covers AGVs, AMRs, and vision-guided vehicles Safety Levels
: Using unverified documentation can void insurance or violate local OSHA regulations.
It does not apply to trucks guided solely by mechanical rails, remotely controlled vehicles, or operation in extreme environments like nuclear zones or public roads. Key Safety Requirements
Dynamic speed adjustments tied strictly to available clearance. Limited requirements for side-sensing during pivots. Iso 3691-4 Pdf

: Areas with restricted space where personnel are excluded.
Areas where the clearance between the truck and infrastructure is less than 0.5 meters. In these zones, personnel access must be restricted, or the vehicle’s speed must be drastically reduced. For many years, EN 1525 was the European standard for AGVs
One of the most actionable parts of an ISO 3691-4 PDF is its classification of operating zones. The standard requires facilities to map out spaces based on the clearance between the vehicle and surrounding structures:
: Sensors must monitor turning paths and reversing maneuvers. 3. Validation and Verification
To ensure compliance, Elena instituted a layered validation plan inspired by the ISO text. First, offline functional testing of control software in a simulated environment, exercising obstacle detection with mannequins and moving carts. Second, controlled on-site trials during low-traffic hours with spotters and emergency-stop redundancy. Third, a formal risk assessment report that documented hazards, severity ratings, and mitigation steps, cross-referenced to clauses from the standard. The vendor provided test logs and component certificates; the maintenance team logged torque specs and sensor calibration dates. Where evidence fell short, Elena paused rollout and demanded modifications. It does not apply to trucks guided solely
