Each of Parts 3-9 inclusive are further divided into particular sections and, by decision of the Technical Board (D68/04
11、7) National Committees need at present only implement in their national language those sections having national applicability. The obligation remains however to announce the full HD in public by titles and numbers, and also to withdraw any conflicting national standards. Page numbering reflects the
12、arrangement into Parts and particular sections, e.g. Page 442-3 is page 3 of particular section C of Part 4. References to other HDs, ENS and international standards are given in the particular parts or sections. The draft was submitted to the formal vote and was approved by CENELEC as HD 620 S1 on
13、1995-1 1-28. The following dates were fixed: - latest date by which the existance of the HD has to be announced at national level (doa) 1996-06-01 latest date by which the HD has to be implemented at national level by publication of a harmonized national standard or by endorsement (dop) 1996-1 2-01
