In addition, machinery shall comply as appropriate with EN 2921 and EN 2922 for
23、hazards which are not covered by this standard. 1 Scope This European Standard specifies safety requirements, and their verification, for the design and construction of screw splitters with horizontal screws, designed to be used by one operator for splitting wood, irrespective of the nature of the p
24、ower source used. On a dual purpose circular saw for firewood/log splitting machine only the log splitter part of the machine is covered by this standard, for circular saws. For firewood saws see prEN 1870-6:1997. This standard describes methods for the elimination or reduction of risks arising from
25、 their use. In addition, it specifies the type of information on safe working practices to be provided by the manufacturer. The list of significant hazards dealt with is given in annex A. Annex A also indicates the hazards which have not been dealt with. This European Standard applies primarily to m
26、achines which are manufactured after the date of issue of the standard. 2 Normative References This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are l
27、isted hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

35、achine where the log is split by the action of a rotating, conical screw. To achieve splitting the log is pressed against the point of the screw (see figures 1a and 1b for an example). 4 Safety requirements 4.1 Electrical equipment The electrical equipment of electrically driven machines shall compl
36、y with EN 60204-1. The degree of protection of all electrical components shall be a minimum of IP 54 in accordance with EN 60529. See also 6.3 s) of this standard for the use of a portable residual current device (PRCD). 4.2 Safety and reliability of control systems Control systems shall be at least
37、 category 1 according to 6.2.2 of EN 954-1:1996. For the purpose of this standard, “safety related control systems“ means the system from and including the initial manual control or position detector to the point of input to the final actuator or element, e.g. motor. Safety related control systems o
38、f this machine include the following: starting; normal stopping; interlocking devices; interlocking with guard locking; initiation of the braking system. BS EN 609-2:1999+A1:2009EN 609-2:1999+A1:2009 (E) 6 For the purpose of this standard “well tried“ according to EN 954-1 means: a) for electrical c
39、omponents that they comply with the relevant standards such as: EN 60947-5-1:1991 (section 3) for control switches with positive opening operation used as mechanically actuated position detectors for interlocking guards and for relays used in auxiliary circuits; EN 60947-4-1 for electromechanical co
40、ntactors and motor starters used in main circuits; HD 22.1 S3 for rubber insulated cables; HD 21.1 S1 for polyvinyl chloride insulated cables if these cables are additionally protected against mechanical damage by positioning (e.g. inside frames); b) for electrical principles that they comply with t
41、he first four measures listed in 9.4.2.1 of EN 60204-1:1997. The circuits shall be “hardwired“. Electronic components alone do not fulfil category 1; c) for mechanical components that they comply with 3.5 of EN 292-2:1991; d) for mechanically actuated position detectors for guards that they are actu
42、ated in the positive mode and their arrangement/fastening and cam design/mounting comply with 5.2.2 and 5.3 of EN 1088:1995; e) for interlocking devices with guard locking that they are a minimum of type 3 according to table 1 of EN 1088:1995; f) for hydraulic components and systems that they comply
43、 with EN 982. 4.3 Starting and stopping 4.3.1 Electrically driven machines A control device for starting and stopping the machine shall be provided within the reach of the operator when he is in the operating position. If the machine is equipped with a mechanical brake (see 4.6.4), the control devic
44、e used for stopping shall comply at least with Category 0, in accordance with 9.2.2 of EN 60204-1:1992. If the machine is equipped with an electrical brake (see 4.6.4), the control device used for stopping shall comply at least with Category 1, in accordance with 9.2.2 of EN 60204-1:1992. If a Categ
45、ory 1 control device is provided for normal stopping, then the following disconnection sequence shall be executed : a) disconnection of the power supply to all drive mechanisms and subsequent activation of the brake ; b) disconnection of the power supply to the brake, after the braking process has b
46、een completed. NOTE: The control device meets also the requirements for emergency stop. 4.3.2 Machines not powered by electricity The machine shall be fitted with a device at the operating position capable to either stop the machine or, e.g. for PTO-driven machines, to disconnect the drive of the ma
47、chine. NOTE 1: This control device meets also the requirements for emergency stop. NOTE 2: The providing of a rope to disengage the power takeoff of the tractor does not fulfil this requirement. BS EN 609-2:1999+A1:2009EN 609-2:1999+A1:2009 (E) 7 4.4 Hydraulic equipment Hydraulic equipment (if provi
48、ded) shall comply with EN 982. Pressurised hoses, lines and components shall be located or shielded so that in the event of rupture, the fluid can not be discharged directly onto the operator when in the operating position. 4.5 Log support A support or holding device shall be provided for the log. T
49、his device shall be designed to allow the log to be split without the need for it to be held in position by the hands or feet. The device shall also prevent the log, or parts of it, falling onto the operator, when he is at the operating position before, during or after splitting. The feeding device (see 4.6.3) can perform the log supporting function. See figures 1a and 1b for an example.
