: AGVs, AMRs, automated towing tractors, and pallet trucks. Environments : Industrial indoor and outdoor workplaces.

Do not rely on free, outdated copies floating around the internet. Invest in the official from your national standards body. Print the verification checklists. Post the stop-distance limits on your shop floor. Train your team on the 2024 amendment.

This is the heart of the standard. It mandates:

Vehicles following fixed paths, magnetic tape, or laser navigation.

When evaluating an ISO 3691-4 PDF or compliance checklist, the standard breaks down safety obligations into three core areas: the machine, the environment, and the system validation. 1. Safety Functions and Performance Levels (PL)

Tens of thousands of autonomous vehicles are now operating in industrial environments worldwide. As these machines become more capable—navigating complex environments, carrying loads that can exceed 2,000 kg, and sharing tight spaces with human workers—the potential consequences of inadequate safety measures become correspondingly severe. A 2‑tonne autonomous forklift moving through a crowded warehouse aisle at speed is a genuine hazard if its sensing, braking, and alerting systems are not rigorously engineered.

: Specific testing methods to ensure the design meets safety guidelines. Operating Zones

The safety of automated guided vehicles (AGVs) and autonomous mobile robots (AMRs) is governed by a critical international standard: ISO 3691-4. As industrial environments become increasingly automated, understanding this framework is essential for manufacturers, integrators, and site operators.
