DINEN 16590-1:2014-11EN 16590-1:2014(E)5 Introduction EN 16590 sets out an app

32、roach to the design and assessment, for all safety life cycle activities, of safety-relevant systems comprising of 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-moun

33、ted and trailed machines used in agriculture. It is also applicable to municipal equipment. It covers the possible 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 (e.g. electric shock, fire, nominal perf

34、ormance level of E/E/PES dedicated to active and passive safety). The control system parts of the machines concerned 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 integr

35、ated parts of a control system, and can either perform solely critical functions or form part of an operational 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

36、 associated with a given hazard (or hazardous situation) under all conditions of use of the machine. This can 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

37、perform a critical function under foreseeable conditions into five performance levels. The performance level of a controlled channel depends on several factors, including system structure (category), the extent of fault detection mechanisms (diagnostic coverage), the reliability of components (mean

38、time to dangerous failure, common-cause failure), design processes, operating stress, environmental conditions 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

39、achieved performance level, EN 16590 defines an approach based on a classification of structures with different 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

40、(e.g. auxiliary valves) to complex systems (e.g. steer by wire), as well as to the control systems of protective 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 requ

41、ired performance level for the safety-related functions to be implemented by E/E/PES safety-related channels. 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 sa

42、fety for E/E/PES that are linked to the performance levels. The structure of safety standards in the field of 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 (ge

43、neric safety standards) deal with one or more safety aspect(s), or one or more type(s) of safeguards that can 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 c

44、ontrols, interlocking devices, pressure sensitive devices, guards). c) Type-C standards (machinery safety standards) deal with detailed safety requirements for a particular machine or group of machines. DIN EN 16590-1:2014-11 EN 16590-1:2014 (E) 6 This part of EN 16590 is a type-B1 standard as state

45、d in EN ISO 12100. For machines which are covered by the scope of a machine specific type-C standard and which have 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. DINEN 16590-1:

46、2014-11EN 16590-1:2014 (E) 7 1 Scope This part of EN 16590 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

47、 used in agriculture. It can also be applied to municipal equipment (e.g. street-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/pr

48、ogrammable electronic systems (E/E/PES), as these relate to mechatronic systems. 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 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
