ISO 18497-3:2024

This document specifies principles for the design of agricultural machinery and tractors utilizing systems (perception, supervisory or other) to prevent unintended excursions beyond the boundary of the autonomous operating zone which are used in agricultural applications and that have partially automated, semi-autonomous and autonomous functions. Additionally, it provides guidance on the type of information to be provided by the manufacturer on safe working practices (including information about residual risks). The autonomous operating zone itself is not within the scope of this document. The autonomous operating zone can include, for example, considerations for the autonomous operating zone location, physical or virtual boundaries, physical boundary types (natural or man-made) and the associated risks with the systems (perception, supervisory or other) to prevent unintended excursions beyond the boundary of the autonomous operating zone design. The purpose of this document is to assist in the provision of more specific safety requirements, means of verification and information for use to ensure an appropriate level of safety for agricultural machinery and tractors with partially automated, semi-autonomous and autonomous functions used in a specified way. This document deals with the significant hazards relevant to agricultural machinery and tractors with partially automated, semi-autonomous and autonomous functions when used as intended and under the conditions of misuse reasonably foreseeable by the manufacturer during normal operation and service. Applicability of the design principles and any additional detailed requirements for design, verification, validation or information for use are outside the scope of this document. When risk assessment concludes that hazards are not significant hazards, the principles of this document do not apply. NOTE Safety requirements for specific non-automated functions of agricultural machinery and tractors can be available in machine-specific type-C standards. This document is not applicable to: — forestry applications; — operations on public roads including relevant requirements for braking and steering systems. This document is not applicable to agricultural machinery and tractors which are manufactured before the date of its publication, or to systems applied to agricultural machinery and tractors put into use before the date of its publication.
