Acceptance Procedure.
Some detailed amendments are made to Part 1. A list of additions and amendments to the particular sections
of Parts 5 to 9 is given in this Part 0.

The text of the draft was submitted to the Unique Acceptance Procedure in June 2002 and was approved by
CENELEC as amendment A2 to HD 620 S1:1996 on 2003-03-01.

The following dates were fixed:

- latest date by which the existence of the amendment
has to be announced at national level (doa) 2003-09-01

- latest date by which the amendment has to be implemented
at national level by publication of a harmonized
national standard or by endorsement (dop) 2004-03-01

- latest date by which the national standards conflicting
with the amendment have to be withdrawn (dow) 2006-03-01
