Description

This part of ISO 25119 provides general principles for the production, operation, modification and supporting processes 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 municipal equipment (e. g. street sweeping machines). This part of ISO 25119 is not applicable to: aircraft and air-cushion vehicles used in agriculture, lawn and garden equipment. 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.Examples included in scope: SRP/CS's limiting current flow in electric hybrids to prevent insulation failure/shock hazards, electromagnetic interference with the SRP/CS, andSRP/CS's designed to prevent fire.Examples not included in scope: insulation failure due to friction that leads to electric shock hazards, nominal electromagnetic radiation impacting nearby machine control systems, and corrosion causing electric cables to overheat.Machine specific standards (type-C standards) can identify performance levels and/or categories or they should be determined by the manufacturer of the machine based on risk assessment.It is not applicable to non-E/E/PES systems (e. g. hydraulic, mechanic or pneumatic).NOTE See also EN ISO 12100 for design principles related to the safety of machinery.
