Introduction
This document is a type-C standard as stated in EN ISO 12100:2010.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
Where for clarity an example of a preventative measure is given, this should not be considered as the only
possible solution. Any other solution leading to the same risk reduction is permissible if an equivalent
level of safety is achieved.
When requirements of this type-C standard are different from those which are stated in type-A or -B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine and/or plant manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine and/or plant users/employers (small, medium and large enterprises);
— service providers, e.g. for maintenance (small, medium and large enterprises).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.

control mode(s)
single machines or groups of interlinked machines of cold flat rolling mills can be operated by different
control modes:
Note 1 to entry: This document distinguishes between control mode(s) and operating mode(s) because there is
neither a common understanding nor a definition in EN ISO 12100 and EN 60204-1. The operating modes (see 3.25)
corresponds to the “control mode” of EN ISO 12100:2010, 6.2.11.9.
3.24.1
manual control mode(s)
3.24.1.1
hold-to-run control
every function is controlled by an operator by means of a button or equivalent device according
EN ISO 12100:2010, 3.28.3
Note 1 to entry: Release of the button/device stops the function (e.g. movement) immediately.
3.24.1.2
single function
functions are started and/or stopped by an operator
3.24.2
semi-automatic control
sequence of functions released once by an operator
Note 1 to entry: The released sequence is automatically stopped at its end. For the initiation of another sequence,
a new command by the operator is required.
3.24.3
automatic control
cycles of successive or parallel sequences once initiated by the operator
Note 1 to entry: If there is no operator intervention, the repetition of the sequences takes place as long as the
running conditions are met.

operating mode(s)
state of the control system allowing to operate the cold flat rolling mill under defined conditions
Note 1 to entry: Such modes are, e.g. production, safe stop, enabling, adjustment, inspection.
Note 2 to entry: The safety level of the operating mode(s) is defined as result of the risk assessment.

operation of machine functions by using an enabling device (as per 3.22)

inching (jog) mode
operation of machine functions using a hold-to-run control device (as per 3.23)
3.25.2
safe stop mode
movement of the involved equipment is prevented through the control system
Note 1 to entry: The required safety level of the safe stop is defined as result of the risk assessment.
Note 2 to entry: Safe stop is not sufficient as a safety measure to perform reconditioning or repair work because
isolation of the equipment from the relevant energy sources is not realized.
Note 3 to entry: Residual risks, e.g. by stored energy must have been secured by other means.
Note 4 to entry: Safe stop mode may also include switching off additional devices, e.g. X-ray.
3.25.3
normal production mode
machine is ready to produce or producing as intended
Note 1 to entry: Production, material handling and activities supporting these processes are covered.
Note 2 to entry: Maintenance according 3.10 is not covered.
3.26
reduced speed
speed, reduced to minimize the hazardous potential without safety monitoring of speed
Note 1 to entry: In case of failure, an increase in speed can occur.
Note 2 to entry: Applies to linear or rotational speed.
Note 3 to entry: Speed reduced without an enabling device means that the movement is so slow that the operator
can move away from this dangerous movement in time. Based on a risk assessment, an enabling device might
therefore be required in some cases, even at a reduced speed (e.g. in narrow spaces).
Note 4 to entry: Examples of reduced speeds include speeds of less than 10 mm/s for presses, less than
250 mm/s for robots, less than 250 mm/s for all non-shearing movements and less than 33 mm/s for shearing or
crushing movements.

for making and shaping of metals - Safety requirements”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 15094:2008-10.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association and supports essential requirements of EU Directive(s).

Introduction
This European Standard is a type C standard as stated in EN ISO 12100:2010.
This document is not applicable to cold rolling mills for flat products manufactured before the date of its
publication.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
Where for clarity an example of a preventative measure is given, this should not be considered as the only
possible solution. Any other solution leading to the same risk reduction is permissible if an equivalent
level of safety is achieved.
When requirements of this type-C standard are different from those which are stated in type-A or -B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine and/or plant manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine and/or plant users/employers (small, medium and large enterprises);
— service providers, e.g. for maintenance (small, medium and large enterprises).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
