DIN EN ISO 25119-2:2018-11

This part of ISO 25119 specifies the concept phase of the 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 may also be applied to municipal equipment (e. g. street-sweeping machines). This part of ISO 25119 specifies the characteristics and categories required of SRP/CS for carrying out their safety-related functions. This part of ISO 25119 is applicable to the safety-related parts of electrical/electronic/programmable electronic systems (E/E/PES), as these relate to mechatronic systems. It does not specify which safety-related functions or performance levels are to be used for particular machines. It covers the possible hazards caused by malfunctioning behaviour of E/E/PES 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 behaviour of E/E/PES safety-related systems.It also covers malfunctioning behaviour of E/E/PES safety-related systems involved in protection measures, safeguards, or safety-related functions in response to non-E/E/PES hazards.
