Tractors and machinery for agriculture and forestry – Safety-related parts of control systems – Part 3: Series development, hardware and software (ISO 25119-3:2018 + Amd 1:2020); German version EN ISO 25119-3:2023 + A1:2023

Abstract

This amendment of ISO 25119 sets out general principles for the design and development of safety-related parts of control systems (SRP/CS) on tractors used in agriculture and forestry and on self-propelled ride-on machines and mounted, semi-mounted and trailed machines used in agriculture. It can also be applied to mobile municipal equipment. It specifies the characteristics and categories required of SRP/CS for carrying out their safety-related functions. It does not identify performance levels for specific applications. It is applicable to the safety-related parts of electrical/electronic/programmable electronic systems (E/E/PES), as these relate to mechatronic systems. It covers the possible hazards caused by malfunctioning behavior of safety-related systems, including interaction of these systems. It does not address hazards related to electric shock, fire, smoke, heat, radiation, toxicity, flammability, reactivity, corrosion, release of energy, and similar hazards, unless directly caused by malfunctioning behavior of safety-related systems. It also covers malfunctioning behavior of safety-related systems involved in protective measures, safeguards, or safety-related functions in response to non-E/E/PES hazards. Examples included within the scope of this document: — SRP/CS limiting current flow in electric hybrids to prevent insulation failure/shock hazards, — electromagnetic interference with the SRP/CS, — SRP/CS designed to prevent fire.
