This European Standard shall be given the status of a national standard, either by publication of an

16、 identical text or by endorsement, at the latest by December 2009, and conflicting national standards shall be withdrawn at the latest by December 2009. 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

17、be held responsible for identifying any or all such patent rights. This document supersedes EN 10028-4:2003.
