This European Standard shall be given the statu

14、s of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2014, and conflicting national standards shall be withdrawn at the latest by February 2014. Attention is drawn to the possibility that some of the elements of this document may be the su

15、bject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights.
