Scope
This part of GB/T 38874 specifies the general principles for the design and development of safety-related components (SRP/CS) of control systems. This part is applicable to agricultural and forestry tractors, self-propelled agricultural machinery, fully and semi-trailer agricultural machinery, agricultural traction machinery, and municipal machinery (such as road sweepers).
This part is not applicable to:
——Agricultural aircraft and agricultural vehicles;
——Lawn and garden equipment.
This part specifies the characteristics and categories required for SRP/CS to perform safety-related functions. This part does not specify performance levels for specific applications.
Note 1: Mechanical-specific Class C standards may specify agricultural performance levels (AgPL) for safety-related functions within their scope. Otherwise, the specification of AgPL is the responsibility of the manufacturer.
This part is applicable to safety components of electrical/electronic/programmable electronic systems (E/E/PES) related to electromechanical systems. This part covers the hazards that may arise from the failure behavior of E/E/PES safety-related systems (including the interaction between these systems). This part does not address hazards related to electric shock, fire, smoke, high temperature, radiation, toxicity, flammability, chemical reactivity, corrosion, or energy release, unless directly caused by a failure of the E/E/PES safety system. This part also covers the failure behavior of E/E/PES safety-related systems under non-E/E/PES hazards, involving protective measures, safeguards, or safety-related functions.
This part includes examples within the following scope:
——SRP/CS limiting current in electric hybrid systems to prevent insulation failure/electric shock hazards;
——Electromagnetic interference of SRP/CS;
——Fire protection design of SRP/CS.
This part does not include examples within th
