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.

measure to observe and assess the current condition as well as fault finding

Note 1 to entry: Measures, e.g. measuring, testing, diagnostics including the determination of the causes of wear

or damage and the derivation of the necessary consequences for the continued use.

Note 2 to entry: 3.10.2 does not cover "material inspection", see 3.17.
3.10.3
reconditioning
foreseeable measure(s) to return to the nominal condition

Note 1 to entry: Foreseeable measures to replace worn parts or parts having expired the foreseen lifetime (could

require dismantling/disassembling). These parts should meet manufacturers' specification.

3.10.4
functional test
checking the functionality of the exchanged or repaired parts

Note 1 to entry: It is maybe required to carry out adjustment work, e.g. test runs, verifying safety functions.

3.11
repair
not foreseeable measure(s) to return to the nominal condition

Note 1 to entry: Measure to replace damaged parts, requires in general dismantling/disassembling. These parts

should meet manufacturers' specification.

pulpit

enclosed room in which the control desk and monitoring facilities for a machine or equipment are located,

used as a permanent workstation
3.20
control stand

free standing control desk (usually situated adjacent to the machine or equipment), used as a temporary

3.21
portable control device

control device which can be used in different places (e.g. control pendant, enabling button, radio control)

3.22
enabling (control) device

additional manually actuated device used in conjunction with a start control which, when continuously

actuated, permits machine function
[EN ISO 12100:2010, 3.28.2]
3.23
hold-to-run control device

control device which initiates and maintains machine functions only as long as the control device is

actuated
[EN ISO 12100:2010, 3.28.3]
3.24
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 standard 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.
