NF EN ISO 3691-4, H96-300-4 (07/2023)

This document specifies the safety requirements and the means of verifying them for driverless industrial trucks (hereinafter referred to as trucks) and their systems. Examples of driverless industrial trucks (trucks as defined in ISO 5053-1:2020) include: “self-guided vehicle”, “autonomous mobile robot”, “robot”, “self-guided trolley”, “tunnel tugger”, “under cart”, etc. This document is also applicable to driverless industrial trucks which are equipped with: — automatic modes which require operator action(s) to initiate or activate such automatic operations; — the capacity to transport one or more attendants (who are considered neither drivers nor operators); — additional manual modes that allow operators to operate the truck manually; or — a maintenance mode that allows manual operation of truck functions for maintenance purposes. This document does not apply to trucks guided solely by mechanical means (rails, guides, etc.) nor to remotely controlled trucks, which are not considered driverless trucks. For the purposes of this document, a driverless industrial truck is a motorized truck, which is designed to operate automatically. A driverless cart system includes the control system, which may be part of and/or separate from the cart, guidance devices, and a power system. Requirements for power sources are not covered by this document. The conditions of the work area have a significant effect on the safe operation of the driverless industrial truck. Work area arrangements to eliminate associated hazards are specified in Annex A. This document is applicable to all significant hazards, hazardous situations or hazardous events, during all phases of the truck's life (ISO 12100:2010, 5.4), as listed in Appendix B, relevant to covered machines when used normally or under conditions of reasonably foreseeable misuse intended by the manufacturer. In particular, this document does not apply to significant hazardous phenomena relating to: — noise; — vibrations; — ionizing and non-ionizing radiation; — laser radiation; — commercial documentation (commercial documents); — the declaration of vibrations transmitted by mobile machines. It does not apply to requirements for additional hazards that may occur: — during operation in severe conditions (e.g. extreme climates, refrigeration applications, intense magnetic fields); — during operation in nuclear environments; — for trucks intended to operate in public areas (see in particular ISO 13482:2014); — during operation on a public road; — during operation in potentially explosive environments; — during operation in military applications; — during operation with specific hygiene requirements; — during operation in environments exposed to ionizing radiation; — during the transport of one or more persons other than the intended companion(s); — when handling loads whose nature may lead to dangerous situations (e.g. molten metals, acids/bases, radiation-emitting materials); — for attendant positions with an elevation function greater than 1,200 mm from the floor/ground to the platform floor. This document does not contain safety requirements for trailers towed behind a dolly. This document does not contain safety requirements for high operator trucks. This document does not apply to trucks manufactured before the date of its publication.
