National foreword
This British Standard is the official English language version of
EN 1504-5:2004.
EN 1504-5 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 acceptability of EN 1504-5 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 ofthe
European Communities.
The Commission in consultation with Member States has agreed a transition
period for 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the national standard(s) will be withdrawn.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 1504-5 is the subject of transitional arrangements agreed under the
Commission mandate. In the UK, there are no corresponding national
standardsofnationalorigin.

B/517, Concrete, to Subcommittee B/517/8, Protection and repair of concrete
structures, which has the responsibility to:
aid enquirers to understand the text;
present to the responsible international/European committee any
enquiries on the interpretation, or proposals for change, and keep the
