It should be noted that, in Germany, CE conformity marking of construction products will be permitted once this standard has been listed in the Bundesanzeiger (German

5、Federal Gazette) and from the date given therein. National foreword This standard has been prepared by Technical Committee CEN/TC 229 “Precast concrete products” (Secretariat: AFNOR, France). The responsible German body involved in its preparation was the Normenausschuss Bauwesen (Building and Civil

6、 Engineering Standards Committee), Working Committee NA 005-07-08 AA Betonfertigteile (SpA zu CEN/TC 229). Amendments This standard differs from DIN EN 12839:2001-12 as follows: a) the scope of the standard now contains more detailed information; b) Clause 3 “Terms and definitions” has been updated

7、to include 3.10 “normal weight concrete” and 3.11 “lightweight concrete”; c) the requirements for material and production have been revised (see 4.1 and 4.2); d) classes D1 and D2 for geometrical properties have been introduced (see 4.3.1); e) requirements for surface characteristics have been speci

8、fied (see 4.3.2); f) durability classes 1 and 2 have been introduced (see 4.3.7); g) the specifications for safety in handling have been revised (see 4.3.8); h) the test methods for determining load bearing capacity and complementary load bearing capacity are now covered in Annex B; i) Annex E “Test

9、 of water absorption” is no longer included; j) Annex ZA has been revised.

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of an identical text or by endorsement, at the latest by July 2012, and conflicting national standards shall be withdrawn at the latest by October 2013. Attention is drawn to the possi

25、bility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12839:2001. This document has been prepared under a mandate given to CEN by the European

26、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. This standard is one of a series of product standards for precast concrete products

27、. For common aspects reference is made to EN 13369:2004, Common rules for precast concrete products, from which also the relevant requirements of EN 206-1, Concrete Part 1: Specification, performance, production and conformity, are taken. The references to EN 13369:2004 by CEN/TC 229 product standar

28、ds are intended to make them homogeneous and to avoid repetitions of similar requirements. Eurocodes are taken as a common reference for design aspects. The installation of some structural precast concrete products is dealt with by EN 13670-1, Execution of concrete structures, which has at the momen

29、t the status of an European prestandard. In all countries, it can be accompanied by alternatives for national application and it shall not be treated as an European standard. The programme of standards for structural precast concrete products comprises the following standards, in some cases consisti

This standard defines in Annex ZA the application methods of CE marking to

34、products designed using the relevant EN Eurocodes (EN 1992-1-1 and EN 1992-1-2).

DIN EN 12839:2012-03 EN 12839:2012 (E) 6 1 Scope This European standard specifies precast products in r

37、einforced or pre-stressed concrete with or without fibres, to be used together or in combination with other elements to erect fences e.g. boundary fences. This European standard covers both mechanical resistance determined by calculation and load bearing capacity determined by testing. Normal weight

38、 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 inclu
