National foreword
This British Standard is the official English language version
of EN 1504-2:2004.
EN 1504-2 is a candidate “harmonized”European standard and fully takes
into account the requirements of the European Commission mandate M/128,
Products related to concrete, mortar and grout, given under the
EU Construction Products Directive (89/106/EEC), and is intended to lead to
CE marking. The date of applicability of EN 1504-2 as a harmonized European
Standard,i.e.the date after which this standard may be used for CE marking
purposes, is subject to an announcement in the Official Journal of the
European Communities.
The Commission in consultation with Member States has agreed a transition
period for the co-existence of harmonized European Standards and their
corresponding national standard(s). It is intended that this period will
comprise a period, usually nine months, after the date of availability of the
European Standard, during which any required changes to national
regulations are to be made, followed by a further period, usually of 12 months,
for the implementation of CE marking. At the end of this co-existence period,
the national standard(s) will be withdrawn.
EN 1504-2 is the subject of transitional arrangements agreed under the
Commission mandate.In the UK,there are no corresponding national
standards of national origin.
