BS EN 16590-4:2014EN 16590-4:2014 (E) 5 Introduction EN 16590 sets out an approach to the design and assessment, for all safety life cycle activities, of safety-relevant systems compris

29、ing electrical and/or electronic and/or programmable electronic systems (E/E/PES) 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 is also applicable to municipal equipment. It covers the possi

30、ble hazards caused by the functional behaviour of E/E/PES safety-related systems, as distinct from hazards arising from the E/E/PES equipment itself (electric shock, fire, nominal performance level of E/E/PES dedicated to active and passive safety, etc.). The control system parts of the machines con

31、cerned are frequently assigned to provide the critical functions of the safety-related parts of control systems (SRP/CS). These can consist of hardware or software, can be separate or integrated parts of a control system, and can either perform solely critical functions or form part of an operationa

32、l function. In general, the designer (and to some extent, the user) will combine the design and validation of these SRP/CS as part of the risk assessment. The objective is to reduce the risk associated with a given hazard (or hazardous situation) under all conditions of use of the machine. This can

33、be achieved by applying various protective measures (both SRP/CS and non-SRP/CS) with the end result of achieving a safe condition. EN 16590 allocates the ability of safety-related parts to perform a critical function under foreseeable conditions into five performance levels. The performance level o

34、f a controlled channel depends on several factors, including system structure (category), the extent of fault detection mechanisms (diagnostic coverage), the reliability of components (mean time to dangerous failure, common-cause failure), design processes, operating stress, environmental conditions

35、 and operation procedures. Three types of failures are considered: systematic, common-cause and random. In order to guide the designer during design, and to facilitate the assessment of the achieved performance level, EN 16590 defines an approach based on a classification of structures with differen

36、t design features and specific behaviour in case of a fault. The performance levels and categories can be applied to the control systems of all kinds of mobile machines: from simple systems (e.g. auxiliary valves) to complex systems (e.g. steer by wire), as well as to the control systems of protecti

37、ve equipment (e.g. interlocking devices, pressure sensitive devices). EN 16590 adopts a risk-based approach for the determination of the risks, while providing a means of specifying the required performance level for the safety-related functions to be implemented by E/E/PES safety-related channels.

38、It gives requirements for the whole safety life cycle of E/E/PES (design, validation, production, operation, maintenance, decommissioning), necessary for achieving the required functional safety for E/E/PES that are linked to the performance levels. The structure of safety standards in the field of

39、machinery is as follows. a) Type-A standards (basic safety standards) give basic concepts, principles for design and general aspects that can be applied to machinery. b) Type-B standards (generic safety standards) deal with one or more safety aspect(s), or one or more type(s) of safeguards that can

40、be used across a wide range of machinery: type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise); type-B2 standards on safeguards (e.g. two-hand controls, interlocking devices, pressure sensitive devices, guards). c) Type-C standards (machinery safety stan

41、dards) deal with detailed safety requirements for a particular machine or group of machines. BS EN 16590-4:2014EN 16590-4:2014 (E) 6 This part of EN 16590 is a type-B1 standard as stated in EN ISO 12100. For machines which are covered by the scope of a machine specific type-C standard and which have

42、 been designed and built according to the provisions of that standard, the provisions of that type-C standard take precedence over the provisions of this type-B standard. BS EN 16590-4:2014EN 16590-4:2014 (E) 7 1 Scope This part of EN 16590 provides general principles for the production, operation,

43、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. stree

44、t-sweeping machines). It specifies the characteristics and categories required of SRP/CS for carrying out their safety functions. This part of EN 16590 is applicable to the safety-related parts of electrical/electronic/programmable electronic systems (E/E/PES), as these relate to mechatronic systems

45、. It does not specify which safety functions, categories or performance levels are to be used for particular machines. 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 assessm

46、ent. It is not applicable to non-E/E/PES systems (e.g. hydraulic, mechanic or pneumatic). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
