This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at

42、 the latest by April 2010, and conflicting national standards shall be withdrawn at the latest by April 2010. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or

43、all such patent rights. This document supersedes EN 201:1997.

For relationship with EU Directive(s), see informativ

44、e Annexes ZA and ZB, which are integral parts of this document. A transition period of one year is permitted following the publication of this document during which the manufacturer may choose to apply either version of the standard. In addition to EN 201:1997, requirements for machines with electri

45、cal axes, machines with L-type configuration, cellular foam injection moulding machines, machines with fluid injectors, and machines safeguarded by light curtains or two-hand control devices are included.
