– data-type field in Pc is expanded from bit 0-4 to 0-6.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2008-06-01
national standard or by endorsement
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2010-09-01
