It should be noted that, in Germany, CE conformity marking of construction products will be permitted once this standard has been listed in the
5、Bundesanzeiger (German 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 Bauwe
6、sen (Building and Civil Engineering Standards Committee), Working Committee NA 005-07-08 AA Betonfertigteile (SpA zu CEN/TC 229). Amendments This standard differs from DIN EN 14992:2007-07 as follows: a) the scope has been extended to include fibre reinforced concrete; b) material requirements have
7、been adjusted to the modified scope; c) Annex Y “Choice of CE marking method” has been deleted; d) Annex ZA has been editorially revised and references to relevant clauses in this standard have been updated.

29、 14992:2007+A1:2012 (E) 5 Introduction The evaluation of conformity given in this standard refers to the completed precast elements which are supplied to the market and covers all the production operations carried out in the factory. For design rules reference is made to EN 1992-1-1. Additional comp
30、lementary rules are provided where necessary. DIN EN 14992:2012-09 EN 14992:2007+A1:2012 (E) 6 1 Scope This European Standard applies to prefabricated walls, made of normal weight or lightweight concrete with dense structure. !Also fibre reinforced concrete (steel, polymer or other fibres covered by
31、 European Standards) may be used.“ !These wall elements“ may have external wall functions (see 3.11) or not, have facing functions (see 3.12) or not or have a combination of these functions. External wall functions could be: thermal insulation (see 3.11.1); sound insulation (see 3.11.2); hygrometric
32、 control (see 3.11.3); or a combination of these. They may be plain, reinforced or prestressed. They may be loadbearing or not. These include: solid walls; composite walls; sandwich walls; lightened walls; claddings. The wall element may also work as a column or beam. 2 Normative references The foll
