5 Safety requirements and/!!!!or protective measures"""" 5.1 General principles Machines conforming to this standard shall satisfy the requirements and all measures set out in this clause. For the reduction of hazards not identified in this document the principles contained in EN ISO 12100 (all parts) !shall" be applied. For hazards which are reduced by application of a B-Level standard such as !EN ISO 13850, EN ISO 13857", 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 machines within the scope 5.2.1 Mechanical equipment 5.2.1.1 Transmission and drive mechanisms !All transmission machinery and drive mechanisms shall be safeguarded by fixed enclosing guards which meet the requirements of EN 953 and A.4." 5.2.1.2 Machinery parts, tools and workpieces 5.2.1.2.1 Unless otherwise specified by 5.3 and with consideration of !usability/applicability", hazardous movements of machinery parts, tools and workpieces shall be safeguarded by the means shown in the following listing given in order of preference: !fixed enclosing guards which meet the requirements of A.4 and EN 953; or" !fencing which meets the requirements of A.3 and A.4; or" !fixed covers which meet the requirements of A.1 and A.4; or" interlocking guards which meet the requirements of B.2 of this document. 5.2.1.2.2 Where the protective measures given in 5.2.1.2.1 cannot be provided, devices shall be provided which will effect a shut down of the hazardous motion before the danger point is reached. Devices which will effect this are: trip devices which meet the requirements of Annex C of this document, such as electrosensitive protective devices or mechanical trip devices; pressure sensitive bars which meet the requirements of EN 1760-2; hold to run control devices which meet the requirements of Clause D.1 of this document, unless otherwise specified in 5.3. 5.2.1.2.3 Safety distances and gap limitations for guard shall comply at least with Tables 1, 3, 4 of
!EN ISO 13857:2008", unless otherwise specified in 5.3. 5.2.1.2.4 Safeguards at crushing, shearing, drawing-in, trapping and friction points are not required if the maximum force of moving parts is limited to 150 N and the contact pressure is limited to 50 N/cm². SIST EN 13457:2005+A1:2010

With respect to some clauses of !EN 60204-1:2006", stated hereafter, the following shall apply: 4.3: A.C. supplies: 4.3.2; D.C. supplies: 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 switching off: Category 0; 9.4: the safety related parts of the control system shall meet the requirements of 5.2.9.4 and 5.2.9.5 of this document; !!!!11.3"""": degree of protection: at least IP 54 (in case of fine dust, a higher degree than IP 54 can be necessary). 5.2.2.2 All operating control devices requiring frequent adjustment for altering process settings shall be located outside the electrical control cabinet. NOTE Controls for routine electrical adjustment are, for instance, to vary feed, speed, time, temperature or pressure. 5.2.3 Thermal protection Hot surfaces within reach shall be avoided or safeguards provided against accidental contact such that, the temperatures of burn threshold for the material concerned and a contact time of less than 1 s, given in
!EN ISO 13732-1", are not exceeded. Selected values on the basis of Figures 2, 5 and 6 of
!EN ISO 13732-1:2008" are given in Annex H. 5.2.4 Protection against fire 5.2.4.1 Machines which generate dust shall be designed and constructed such, that dust accumulation which may be ignited by a machine overheating or by sparks is prevented, according to EN 13478. 5.2.4.2 Enclosed zones of a machine where dust accumulation could cause a fire hazard shall be cleanable by the operator without the need for auxiliary means to gain access. These zones shall not contain danger points caused by mechanical hazards. Information on these zones and cleaning methods shall be included in the instructions for use, together with recommendations on disposal of the dust. 5.2.4.3 For collection, transportation and disposal of generated dust the machines shall be equipped with a provision for dust removal (e.g. dust collection bag or bin). Dust collectors shall be made out of non-flammable materials. Dust filters shall be made flame retardant. 5.2.4.4 Internal dust exhaust equipment shall be interlocked with the drive mechanism of the machine. !The parts of the control system related to the interlocking shall present at least a performance level "c" defined in accordance with EN ISO 13849-1." SIST EN 13457:2005+A1:2010
EN ISO 11688-1 and EN ISO 11688-2. Examples of noise control measures are: a) reduction of vibration through static and dynamic balancing of rotation parts; b) reduction of vibration within the machine by reducing both the mass of moving parts and their acceleration; c) reduction of impactive over-clearance of rotational bearings by application of positive preloading; d) proper choice and design of energy transfer-components to eliminate bouncing; e) proper choice and design of transmission components (gears, pulleys, belts, bearings etc.); f) proper design of machine structures taking into account vibration damping and avoidance of structural resonance; g) sound deadening of pneumatic discharges, vibration damping of hydraulic circuits. The above list is not exhaustive. Other noise control measures with the same or better efficacy can be used by a manufacturer. 5.2.6 Fumes and dust detrimental to health Reduction of risk to health from fumes and dusts shall be carried out by observing the state of the art and Clause 6 of EN 626-1:1994. The machine shall either be designed with its own filter system or designed to enable it to be fitted to a suitable capture hood. Because of the range of materials concerned in the process covered by this document, it is not possible to give more precise precautions. In recirculating systems dust filter shall meet dust class L and penetration 1 % of Annex AA of EN 60335-2-69:2003. 5.2.7 Ergonomics Machine design shall incorporate the ergonomic principles described in 4.8 of EN ISO 12100-2:2003 and EN 614-1. In particular, the design shall consider: the working height; operator posture and movement; operator physical strength especially during setting, in accordance with EN 1005-2 and
EN 1005-3; ease of access and compatibility of control actuators in accordance with EN 894-3; operator access to the working area in accordance with EN 547-1 and EN 547-2; if necessary, a suitable platform in accordance with EN ISO 14122-2 shall be provided; the platform shall be non-sloping; design of displays in accordance with EN 894-2; additional local lighting on the machine in accordance with EN 12464-1 !deleted text".
