European foreword
This document (EN 14487-1:2022) has been prepared by Technical Committee CEN/TC 104 “Concrete
and related products”, the secretariat of which is held by SN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by May 2023, and conflicting national standards shall be
withdrawn at the latest by May 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 14487-1:2005.
In comparison with the previous edition, the following technical modifications have been made:
— Table 3 has been added;
— Table 13 has been modified;
— Normative references have been updated.
This document has taken EN 206 as a basis. Some clauses which apply to sprayed concrete refer to
EN 206 because of their importance. Other clauses have been modified to meet the specific requirements
of sprayed concrete.
This document is only operable with product standards for constituent materials (i.e. cement, aggregates,
additions, admixtures, fibres and mixing water) and related test methods for sprayed concrete which
form the package defined below. For this reason, the latest date of withdrawal of national standards
(DOW) conflicting with this document is determined by TC 104 to be DAV + 6 months.
Any feedback and questions on this document should be directed to the users’ national standards body.
