Introduction
This European Standard is a type C standard as stated in EN 1070.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this standard.
1 Scope
1.1 This European Standard specifies safety requirements for design, construction, operation, adjustment,
setting, cleaning and maintenance of a machine.
1.2 This standard covers the following machines (see annex C and Figures 1 and 2 for typical configurations):
a) horizontal rotating vessels;
b) inclined rotating vessels.
1.3 This standard does not apply to machines using substances containing solvent, that would generate fume
and/or vapour detrimental to health, or that may lead to fire or explosive atmosphere.
1.4 This standard takes account of intended use, foreseeable misuse, component and systems failure.
The machines are for fixed installation.

5 Safety requirements and/or measures
NOTE For hazards not covered by this European Standard which are to be reduced by the application of a B-standard
such as EN 292, EN 294, EN 418, EN 953, EN 60204-1 etc., a risk assessment is necessary to establish the requirements of
the B-standard to be applied. This specific risk assessment is part of the general risk assessment of the machine.
Machinery shall comply with the safety requirements and/or measures of this clause.
In addition, the machine shall be designed according to the principles of EN 292 for hazards relevant but not
significant which are not dealt with by this standard.
5.1 General
See 1.1.2 of annex A of EN 292-2:1991/A1:1995.
5.2 Common requirements concerning rotating process vessels
5.2.1 Mechanical equipment
5.2.1.1 Safeguarding against the hazards generated by moving transmission parts (such as pulleys, belts,
gears, rack, etc.) shall be ensured by:

fixed enclosing guards in accordance with EN 953 and 4.2.2.2 of EN 292-2:1991/A1:1995,
or

movable interlocking guards in accordance with EN 953, EN 1088 and 4.2.2.3 of
EN 292-2:1991/A1:1995.
5.2.1.2 Hazardous motions of moving machinery parts, shall be safeguarded by:
12

---------------------- Page: 13 ----------------------

EN 13114:2002 (E)

fixed enclosing guards or covers which satisfy EN 953 and 4.2.2.2 of EN 292-2:1991/A1:1995,
or

fixed distance guards which satisfy EN 953, 4.2.2.1 of EN 292-2:1991/A1:1995 and the distances given in the
appropriate Table (1, 3 or 4) of EN 294:1992.
5.2.1.3 All the guards mentioned in 5.3 and 5.4 shall be in accordance with clause 5 of EN 953:1997 (design
and construction) and shall be designed and manufactured in such a way as to keep all their functions during the
2
application of a force of 800 N to the central zone of the guard, distributed over an area of approximately 0,01m .
On release of the force no detectable distortion of the guard shall remain.
5.2.1.4 Where the above measures cannot be applied the following protective devices shall be provided which
will effect a shutdown of the hazardous motion before reaching the danger point.
Suitable protective devices are:

movable interlocking guards which satisfy EN 953 and EN 1088, 4.2.2.3 of
EN 292-2:1991/A1:1995 and the distances given in the appropriate Table (1 or 3) of EN 294:1992;

trip devices, such as:

electrosensitive protective devices satisfying EN 61496-1, prEN 61496-2 and EN 999;

pressure sensitive protective device satisfying prEN 1760-2 type 3.1 or 3.2.
5.2.2 High pressure fluid and burst component part ejection
If a machine is fitted with hydraulic/pneumatic equipment a loss of fluid under high pressure may arise and result in
a hazard of impact either directly or by impelled objects.
For liming and vegetable retanning drums it is necessary to provide the machine with a device to vent the inside of
the rotating body. For maintenance of the venting device see 7.1.5.d of this standard.
The risk of injury caused by escaping spurts/jets of fluid or impelled objects shall be reduced to the lowest practical
level by the provision of fixed enclosing guards or solid screens.
The requirements included in EN 982 (hydraulic equipment), EN 983 (pneumatic equipment) and 7.2.b of this
standard are applicable.
5.2.3 Electrical equipment (for all machines)
5.2.3.1 Electrical systems and equipment shall be in accordance with EN 60204-1.
Control and safety devices shall be protected to IP55 level if working in a wet process and IP54 if working in a dry
process. Specific levels of protection are defined in EN 60529.
5.2.3.2 All operating controls requiring adjustment for changing the working process shall be located on the
outside of the electrical cabinet.
NOTE Controls for routine electrical adjustment are for example time, speed.
5.2.4 Slip, trip and fall hazard
The floor and catwalk where machines used for wet processes are installed can become slippery because of water,
grease and chemical discharge from the machine.
13

---------------------- Page: 14 ----------------------

EN 13114:2002 (E)
The manufacturer shall provide a means for the intended discharges of liquids from the machine and include details
of the termination of this means in the information for use, together with information on the volume and quality of
the liquids.
The manufacturer shall also include in the information for use recommendations for the installation of means to
collect and remove unintended discharges such as gutter and canals, floor slope or use of non-skid materials.
5.2.5 Noise
5.2.5.1 Noise reduction at source and by protective measures at the design stage: noise reduction shall be
achieved as an integral part of the design by:

taking account of the measures to control noise at source given in EN ISO 11688-1,

incorporating one or more of the measures indicated in annex A as examples.
NOTE EN ISO 11688-2 is, for machine designers, a useful source of information on noise generation mechanisms.
5.2.5.2 Noise reduction by information: if it is known that, after taking possible measures to control noise at the
design stage, further protection of the operators is necessary, the instruction handbook shall give additional
information (see 7.1.1).
5.2.6 Dust, fume and vapour emission
Some working stages rotating vessels may cause emission of dust or of harmful and/or toxic vapours. These shall
