22、014EN 15811:2014 (E) 4 Introduction 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 (generic safety standards)
23、 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-hands controls, interlocking d
24、evices, pressure sensitive devices, guards); c) Type-C standards (machinery safety standards) deal with detailed safety requirements for a particular machine or group of machines. This European Standard is a type-C standard as stated in EN ISO 12100. When provisions of this type-C standard are diffe
25、rent from those which are stated in type-A or type-B standards, the provisions of this type-C standard take precedence over the provisions of the other standards for machines that have been designed and built according to the provisions of this type-C standard. BS EN 15811:2014EN 15811:2014 (E) 5 1
26、Scope This European Standard specifies the safety requirements and their verification for the design and construction of fixed guards to be opened or removed by the use of a tool and interlocking guards with or without guard locking for moving parts of the power transmission on self-propelled ride-o
27、n machines and mounted, semi-mounted or trailed machines used in agriculture. In addition, it specifies the type of information on safe working practices (including residual risks) to be provided by the manufacturer. It deals with the significant hazards (as listed in Annex A), hazardous situations
28、and events relevant for fixed guards to be opened or removed by the use of a tool and interlocking movable guards of moving parts of power transmission used as intended and under the conditions reasonably foreseeable by the manufacturer (see Clause 4 and Clause 5). It is not applicable to guards of
29、moving parts of the power transmission of: agricultural and forestry tractors, aircraft and air cushion vehicles used in agriculture, lawn and garden equipment, or PTO drive shafts between agricultural and forestry tractors and mounted or towed implements. 2 Normative references The following docume

33、 machine. Selection of appropriate measures shall take into consideration the complete strategy for risk reduction specified in EN ISO 12100:2010, Clause 5, and shall consider both normal operation and service operations as specified in the operators manual. When guarding is shown to be an appropria
34、te means for risk reduction, the selection of an appropriate guard for a particular type of machine or hazard zone, shall take into account that: BS EN 15811:2014EN 15811:2014 (E) 6 a fixed guard as specified in 5.2.1 is simple and shall be used where access of an operator to the hazard zone is not
35、or infrequently required during normal operation (operation without malfunction) of the machinery; in case of frequent access, this inevitably leads to the fixed guard not being replaced. This requires the use of alternative protective measure (e.g. interlocking guard, sensitive protective equipment
36、). The frequency of access used in the selection of the type of guard shall account for any difficult working conditions that could increase the need for access. 5 Requirements 5.1 General The design of guards shall take into consideration the risks to the operator and other persons without preventi
37、ng the proper function of the machine or generating other hazards such as preventing drainage, debris accumulation, blockages or malfunctions. Guards shall be designed and constructed in such a way that normal operation and service of the machine can be readily carried out. Guards can be formed from
38、 rigid mesh or grille. The size of openings permitted in guards depends on the distance between the guard and the hazard/hazardous area and shall be in accordance with EN ISO 13857:2008, Tables 3, 4 or 6 as applicable. The strength of guards shall comply with EN ISO 4254-1. 5.2 Additional requiremen
39、ts for fixed guards 5.2.1 Fixed guards shall be securely held in place: by permanent fixing (e.g. by welding, riveting, one-way screws); or by means of fasteners such as screws and nuts which require a common tool for opening or removal. The fixing system shall remain attached to the guard or to the
40、 machine when the guards are removed. Where possible, the guards shall be incapable of remaining in place without their fixings; or by means of hinges and a locking system, which can only be released using a tool, (in order to make opening an intentional action) and which can be automatically closed
41、 without the use of a tool. 5.2.2 In case of fixed guards which can be opened or removed in order to provide access to hazardous power transmission parts which continue to rotate or move after the power supply is disengaged, the following requirements apply: a safety sign in the immediate vicinity o
42、f the hazardous parts (e.g. on the outside of the guard) shall be provided to give a warning of the hazard; and a visible (while in the hazard area) or audible indication, starting from the moment that the power supply is disengaged until the hazardous parts stop rotating or moving. It is not requir
43、ed that the indication is given when the machine is in ground motion / travelling. 5.3 Additional requirements for interlocking guards Interlocking guards shall: as far as possible, remain attached to the machine when open, and BS EN 15811:2014EN 15811:2014 (E) 7 be designed and constructed in such
44、a way that they can be adjusted only by means of an intentional action. Interlocking guards shall have an interlocking device which: prevents the start of the hazardous transmission parts when the guard is open, and gives a command to disengage hazardous power transmission parts when the guard is op
45、ened. If the run-down time of the power transmission parts exceeds the time needed for an operator to reach them, a guard locking device shall be provided which: locks the guard when closed, and keeps the guard locked until the hazardous movement has stopped. 6 Verification of safety requirements or
46、 protective measures See Table1. Table 1 List of safety requirements and/or protective measures and their verification Clause Verification Inspection Measurement Test with reference 5 X X Shall be verified by carrying out normal operation and service of the machine as specified in the operators manu
47、al. 7 Information for use 7.1 Operators manual The manual shall include warnings about the significant residual risks and how these are to be controlled, as well as any training requirements (see 5.2). 7.2 Safety signs A safety sign in the immediate vicinity of the hazardous parts (e.g. on the outsi
48、de of the guard or access door) shall be provided to indicate the rotation of parts, if applicable (see 5.2.2). BS EN 15811:2014EN 15811:2014 (E) 8 Annex A (informative) List of significant hazards Table A.1 specifies the significant hazards, significant hazardous situations and significant hazardou
49、s events that have been identified as being significant to the guards for moving parts of power transmission covered by this European Standard and which require specific action by the designer or manufacturer to eliminate or to reduce the risk.
