What is ISO 3691-4?

ISO 3691-4, “Industrial trucks – Safety requirements and verification – Part 4: Driverless industrial trucks and their systems” is the most important international standard for automated guided vehicles (AGV) and vehicle systems (AGVS). It was published in 2020 and applies to manufacturers as well as operators. It defines the requirements (performance levels) of the safety functions of AGV and AGVS, such as the setup for the detection of persons, modes of operation and the braking system. It also describes the procedure for risk reduction and validation of the automated functions, to guarantee smooth and safe operation of the AGV and AGVS in their final installation environment.
