This document specifies principles for the design of autonomous operating zones for agricultural machinery and tractors that 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 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 all the significant hazards, hazardous situations and events, relevant to agricultural machinery and tractors with partially automated, semi-autonomous and autonomous functions when used as intended and under the conditions of misuse foreseeable by the manufacturer during normal operation and service. NOTE 1 While this series of documents gives principles for the design, verification, validation and provision of information for use, the detailed requirements are dependent on the use case. Therefore, the design principles given in this document need to be extended and clarified by the use of relevant specific (type-C) standards, when available, or by the manufacturer of the machine using a risk assessment. Applicability of the design principles and any additional requirements, for design, verification, validation or information for use are outside the scope of this document. NOTE 2 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.
