Foreword
This European Standard has been prepared by Technical Committee CEN/TC 143 "Machine
tools - Safety", the secretariat of which is held by SNV.
This European Standard shall be given the status of a national standard, either by publication of
an identical text or by endorsement, at the latest by January 2002, and conflicting national
standards shall be withdrawn at the latest by January 2002.
Annex A is normative. Annexes B to D and ZA are informative.
This European Standard 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 EC–Directives, see informative annex ZA which is an integral part of this
standard.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of
the following countries are bound to implement this European Standard: Austria, Belgium,
Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy,
Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United
Kingdom.
0 Introduction
This European Standard is a type C standard as stated in EN 292–1.
When provisions of this type C standard are different from those which are stated in type A or B
standards, the provisions of this type C standard take precedence.
Machining centres present a wide range of hazards, not least from their wide application as
rotating tool, 'stationary' workpiece machine tools, for general purpose cutting of cold metal work
material.
Protection of operators and other persons from contact with moving cutting tools, especially
when being rapidly rotated in the spindle, or being swung from a tool magazine to the spindle
during power-operated tool changing, or from contact with fast–moving workpieces, is of great
importance.
When power–operated mechanisms are provided for workpiece transfer, they can also create
hazardous situations during loading/unloading and workpiece alignment or clamping.
Total enclosure of the work zone using guards during cutting is practicable for smaller
machines. The requirements for access to the work zone of large machines used for the
processing of a wide range of workpiece configurations can require that operators are
safeguarded by other means (e.g. perimeter fencing, protective devices at the operating
position).
Pendant controls enable operators to move around the machine, especially large machines, and
to view the work zone, the load/aligning, clamping, cutting, or unloading operations,
maneuvering the pendant control as they move.
The significant hazards covered by this standard are those listed in clause 4. The safety
requirements and/or protective measures to prevent or minimize those hazards identified in
Table 1 and procedures for verification of these requirements or measures are found in clause 5.
The figures in annex C are examples only and are not intended to illustrate the only
interpretation of the text.
1 Scope
1.1 This standard specifies the technical safety requirements and protective measures to be
adopted by persons undertaking the design, construction and supply (including installation and
dismantling, with arrangements for transport and maintenance) of machining centres (see 3.1).
1.2 This standard takes account of intended use including reasonably foreseeable misuse,
maintenance, cleaning, and setting operations. It presumes access to the machine from all
directions. It describes means to reduce risks to operators and other exposed persons.
1.3 This standard also applies to the workpiece transfer devices when they form an integral part
of the machine.
1.4 This standard deals with significant hazards relevant to machining centres when they are
used as intended and under the conditions foreseen by the manufacturer (see clause 4).
1.5 Hazards arising from other metal working processes (e.g. grinding, turning, forming, EDM,
laser processing) are covered by other standards (see Bibliography).
1.6 This standard applies to machines which are manufactured after (its date of publication).
2 Normative references

publications. These normative references are cited at the appropriate places in the text, and the
publications are listed hereafter. For dated references, subsequent amendments to or revisions
of any of these publications apply to this European Standard only when incorporated in it by
amendment or revision. For undated references the latest edition of the publication referred to
applies (including amendments).
