The following main changes have been made: a) terms and definitions, symbols and normative references have been updated; b) clause on wind loads has been revised, whereby the wind load assumptions have been classified into four instead of the current three wind load zones and have been taken over together with the wind-zone map from DIN 1055-4:2005-03; c) clause on ice loads has been revised, whereby four instead of the current three ice load zones have been introduced and an informative geographical ice load map for these four zones has been added in Annex S; d) clause "maintenance facilities" has been revised.
