This European Standard shall be given the st
14、atus of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2005, and conflicting national standards shall be withdrawn at the latest by December 2005. According to the CEN/CENELEC Internal Regulations, the national standards organizations of
