Foreword
This document (prEN 12839:2007) has been prepared by Technical Committee CEN/TC 229 “Precast
concrete products”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 12839:2001.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.
1 Scope
This European standard covers precast products in reinforced or prestressed concrete with or without fibres,
produced in long series with the same design and mechanical resistance verified by testing to be used
together or in combination with other elements to erect fences e.g. boundary fences.
Normal weight concrete or light weight concrete elements include posts, solid or open panels, slabs, rails,
spurs, struts and base panels.
The intended uses may be nonstructural or lightly structural.
It provides for the evaluation of conformity of elements to this European Standard. Marking conditions are
included.
NOTE Annex A intends to provide information on the possible types of fences in which these elements may be part
of.
