5 Safety requirements and/or measures 5.1 General Machinery shall comply with the safety requirements and/or protective measures of this clause. In addition, the machine shall be designed according to the principles of EN ISO 12100 for hazards relevant but not significant which are not dealt with by this European Standard (e.g. sharp edges of structural parts). For hazards which are reduced by application of a B-Level standard such as EN 294, !EN ISO 13850", EN 60204-1 etc., the manufacturer shall carry out a risk assessment to establish the requirements of the B-standard to be applied. This specific risk assessment shall be part of the general risk assessment of the machine. 5.2 Common requirements for all cutting and punching machines NOTE Some specific requirements in 5.3 are deviating from the following common requirements. 5.2.1 Mechanical Equipment 5.2.1.1 Safeguarding against the hazards generated by moving transmissions parts (such as pulleys, belts, gears, rack, etc.), shall be ensured by:  fixed enclosing guards in accordance with EN 953. !The fixing systems of these guards shall remain attached to these parts or to the machine when the parts are removed."  movable interlocking guards without guard locking in accordance with EN 953, EN 1088, and Annex A of this European Standard (the specific subclauses will indicate if A1, A2 or A3 of Annex A will apply). 5.2.1.2 Hazardous motion of moving machinery parts, feed systems, tools and workpieces shall be safeguarded by the following, on the basis of risk assessment in accordance with !EN ISO 14121-1" and taking into consideration the highest level of protection available:  fixed enclosing guards or covers which satisfies EN 953;
 fixed distance guards which satisfy 3.2.2 of EN 953:1997 and the distances given in the appropriate Table (1, 3 or 4) of EN 294:1992. !The fixing systems of these guards shall remain attached to these parts or to the machine when the parts are removed." Where it is impossible to provide these protective measures, devices shall be provided which will !cause" a shutdown of the hazardous motion before the danger zone is reached. Devices which will affect this are:  movable interlocking guards without guard locking which satisfy EN 953, EN 1088, and Annex A of this European Standard; NOTE For these machines, movable interlocking guards without guard locking are considered acceptable because of the short stopping time of the moving parts.  trip devices, such as: SIST EN 12044:2005+A1:2009

mechanical trip bars satisfying Annex C of this European Standard;  two-hand control devices which satisfy EN 574 and EN 999. Specific applications, if necessary, are given in the relevant subclause for each machine in 5.3. 5.2.1.3 On travelling head cutting presses or beam cutting presses with double tray feeder which may be operated alternately by two persons, one at the front and the other at the rear, front and rear safeguarding arrangements shall be identical; the design shall ensure that any motion can be actuated only by the operator engaged in the working cycle, while the safeguarding arrangement on the side of the other operator is operational. 5.2.2 Electrical equipment 5.2.2.1 Electrical systems and equipment shall be in accordance with EN 60204-1. With respect to some clauses of !EN 60204-1:2006", stated hereafter, the following shall apply:  4.3:
A.C. supplies: in accordance with 4.3.2; D.C. supplies: in accordance with 4.3.3;  6.2: Protection in accordance with 6.2.2 or 6.2.3 and, where applicable 6.2.4;  9.2.5.3/4: Stop function and emergency stop function: stop category 0 or 1;  9.4: the safety related parts of the control system shall meet the requirements of this European Standard;  !11.3": degree of protection: at least IP 54. 5.2.2.2 All operating controls requiring routine adjustment for changing the working process shall be located outside the electrical cabinet. NOTE Controls for routine electrical adjustment are for example feed, speed, time, temperature or pressure variation. 5.2.3 Noise reduction 5.2.3.1 Noise reduction at source by design Noise reduction shall be carried out by incorporating, as an integral part of the design, one or more of the following features: a) reduction of vibration through static and dynamic balancing of rotating parts; b) reduction of vibration within the machine by reducing both the mass of the moving parts and their acceleration; c) reduction of impactive overclearance of rotational bearings by application of positive preloading; d) proper choice and design of the energy-transfer components to eliminate bouncing; e) proper choice and design of transmission components (gears, pulleys, belts, bearings and so on); f) proper design of machine structures taking into account vibration damping and avoidance of structural resonance. SIST EN 12044:2005+A1:2009

5.2.3.2 Noise reduction by protective devices If it is not possible to achieve the noise reduction at the source by design methods, then the following shall be considered: a) antivibration mountings should be fitted to reduce vibration transmission to the floor; b) sound deadening of pneumatic discharges, vibration damping of hydraulic circuits. Other devices with identical or greater efficacy may be used by the manufacturers. 5.2.3.3 Noise reduction by information If consideration of noise reduction at the design stage shows that noise emission levels, after taking all possible technical measures, will be so high that further protection of the operator will be necessary, the information for use shall contain additional information !(see 7.4)". 5.2.4 High pressure fluid To prevent high pressure ejection of fluid or ejection of a part of a burst component, hydraulic and pneumatic systems shall satisfy 4.10 of EN ISO 12100-2:2003, EN 982 and EN 983. 5.2.5 Control systems 5.2.5.1 All machines shall have a start control and a stop control fitted at the working zone. The control system shall automatically adopt a safe condition if any of the energy inputs are unavailable. Hydraulic control equipment shall be in accordance with EN 982. Pneumatic control equipment shall be in accordance with EN 983. Electrical control equipment shall be in accordance with 5.2.2 and specific control requirements of individual machines (see 5.3). Design of display and control actuators shall comply with the ergonomic requirements included in EN 894-1, EN 894-2 and EN 894-3. 5.2.5.2 On machines which are equipped with electrosensitive protective devices, cycle re-start may be initiated automatically by this device under the following conditions:
 device detects the reestablishment of a safe condition;  recurring access is required for each working cycle;  it is not possible to stand inside the guarded area;  working cycle time of the machine does not exceed one minute. !The protective device shall be of type 4 in accordance with EN 61496-1 and the related parts of the control system shall comply with performance level "e" as defined in EN ISO 13849-1." SIST EN 12044:2005+A1:2009

as the safeguarding used;  !be in accordance with Annex D and comply with performance level "c" as defined in EN ISO 13849-1." 5.2.5.6 The electrical safety-related parts of control systems shall be designed in such a manner that the failure of any electrical component cannot initiate automatic closing movement, !complying as a minimum with performance level "d" as defined in EN ISO 13849-1." The use of programmable electronic systems (PES) shall not reduce any level of safety laid down in this European Standard. Safety related functions
shall not rely solely on single channel PES.  This requirement is met by the use of, for example:an
additional hardwired control system;  duplicated solid state channels (not programmable);  programmable electronic system with established safety level. 5.2.5.7 The requirements of 5.2.5.4, 5.2.5.5 and 5.2.5.6 do not apply if access to the danger zone is possible only after hazardous motion has been positively blocked by mechanical means, independent of the controls.
5.2.5.8 Machines designed for several operating modes, and which can be operated by means of various safety devices, shall be equipped with mode selection devices in accordance with 4.11.9 and 4.11.10 of
EN ISO 12100-2:2003. Operating modes are e.g. automatic operation, manual
