maximum force of moving parts is limited to 150 N and the contact pressure is limited to 50 N/cm².
5.2.1.3 Operator's standing area
The surface of an area where the operator stands for recurring manual intervention shall give a good grip and steps

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

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 and prEN 12464-2.
5.2.8 Pressurized fluid systems
Equipment of hydraulic and pneumatic systems shall meet the requirements of 4.10 of EN ISO 12100-2:2003, EN
982 and EN 983.
Flexible pipes containing pressurized hydraulic or pneumatic fluids shall be protected by sufficient distances or by
guards to prevent wear caused by other machine parts.
5.2.9 Control systems
5.2.9.1 Control systems shall comply with the following general requirements:
 for electrical systems: 5.2.2 of the present standard and Clause 9 of EN 60204-1:1997;
 for pneumatic systems: the requirements of EN 983;
 for hydraulic systems: the requirements for EN 982.
5.2.9.2 Safety related parts of the control systems shall be designed in accordance with the principles of
EN 954-1. Safety related parts are for example emergency stopping systems, safety interlocking systems for
guards, safety devices, the monitoring, emergency system for the ventilation in case of explosion risk.
5.2.9.3 In general the following principles apply:
 safety related parts of pneumatic and hydraulic safety related parts of the control system shall at least comply
with category 1 of EN 954-1:1996;
 safety related parts of electrical/electronic control systems shall normally at least comply with category 3 of
EN 954-1:1996. Depending on the risk assessment, the safety related part of the control system related to the
emergency stop system shall at least comply with category 1.
This requirement includes that safety related functions shall not solely rely on normal traditional programmable
electronic systems (PES): the required safety category shall be realised by the use of, for example, an additional
hardwired circuit, a redundant solid state channel, or other provisions for redundancy.
 when using a category 2 (based on the risk assessment) the test interval shall be as short as required and not
more than 4 hours.
 the parts of the control system processing the signal of a safety device shall comply at least with the safety
category of that device.
5.2.9.4 Interlocking devices for safeguards and devices for muting of safeguards shall only be operated by
position sensors (pressure, time or programme controlled commands of interlocks alone are not permitted).
Electrical position sensors shall comply with EN 60947-5-1 and be appropriate for functioning in the positive mode
according to EN 1088. According to 5.1 of EN 1088:1995, non-positive mode actuation is only allowed in
conjunction with a detector with positive mode actuation, notably to avoid common cause failures.
5.2.9.5 Appropriate provisions shall be provided, taking into account the requirements of EN 1037,
EN 982, EN 983, EN 60204-1, against all hazards related to failure of the power supply, including irregularities,
unexpected reconnection after interruption of the power supply, or when the control circuit has been switched off.
5.2.9.6 Foot-actuated controls which actuate hazardous motion and which are not fixed to the machine, and
foot-actuated controls at standing working positions, shall be provided with a cover around the foot-actuated control
to prevent accidental operation.
5.2.9.7 The machine shall have sufficient immunity in relation with electromagnetic disturbances to enable
them to operate safety as intended and not fail to danger when exposed to the levels and types of disturbances
intended by the manufacturer.
The manufacturer shall select or design, install and wire the equipment and sub-assemblies taking account of the
recommendations of the suppliers of the sub-assemblies.
5.2.10 Additional safety devices
5.2.10.1 Emergency stop
The emergency stop shall meet the requirements of EN 418. Electrical emergency stops shall comply with
EN 60204-1:1997, 9.2.5.4.2. For other types of energy, the emergency stops shall comply with the first two
paragraphs of that clause.
5.2.10.2 Mode selection device
Machines designed for several operating modes or which can be operated by means of various safety devices
operating at different levels shall be equipped with mode selection devices which meet the requirements of 4.11.9
and 4.11.10 of EN ISO 12100-2:2003. Each position shall be secured e.g. by the use of a lock, or an access code,
etc.
Operating modes are, e.g. automatic operation, hand controlled operation, tool changing, adjustment, etc.
The act of mode selection by itself shall not initiate an operation. Separate actuation by the operator shall be
required.
5.2.11 Aids for transportation
Splitting, skiving, edge trimming, strip cutting, cementing machines, cement dryers and their auxiliary equipment
shall be constructed and equipped in such a manner that they can be safely transported.
The requirement is met by providing points for fitting the transport means and a machine frame design which allows
the use of a fork lift truck or a roller truck. Any special equipment or procedure required for safe transportation or
installation of the machine shall
