This document (prEN 15094:2019) has been prepared by Technical Committee CEN/TC 322 “Equipment

for making and shaping of metals - Safety requirements”, the secretariat of which is held by DIN.

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).

For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this

This document is not applicable to cold rolling mills for flat products manufactured before the date of its

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

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

This document is of relevance, in particular, for the following stakeholder groups representing the market

— 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

The above-mentioned stakeholder groups have been given the possibility to participate at the drafting

This document specifies the general safety requirements for cold rolling mills for flat products as defined

This document is applicable to: Plant (machinery, equipment, devices according Annex D) used for the

manufacturing of metal cold rolled flat products from the material supply from entry (1), via the mill

stand(s) (2) with roll changing devices (4), to the material removal (3) (see Figure 1).

— Coil transporting system before coil take-over-point at the entry section and after coil take-over-

point at the exit section, e.g. hook conveyors, overhead cranes, fork lift and railway trucks and other

— Process technology (e.g. systems for rolling lubricant, compressed air, treatment of water, cleaning

NOTE 1 Special requirements for protection of persons in case of using asphyxiant gases used in firefighting

This document deals with foreseeable significant hazards, hazardous situations and events relevant to

cold rolling mills for flat products, when used as intended and under conditions of misuse which are

reasonably foreseeable by the manufacturer. It provides the requirements to be met by the manufacturer

to ensure the safety of persons and property during transport, commissioning, operation and de-

commissioning, as well as in the event of foreseeable failures or malfunctions that can occur in the
