35、ntroduction 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 and resistance to fire, reference is made to EN 1992-1-1 and EN 1992-1-2. Ad

36、ditional complementary rules are provided where necessary. 4.3.3 and 4.3.4 include specific provisions resulting from the application of EN 1992-1-1, and EN 1992-1-2 rules made specific for the concerned product. The use of these provisions is consistent with a design of works made with EN 1992-1-1

37、and EN 1992-1-2.

38、eria and evaluation of conformity for precast ribbed elements made of reinforced or prestressed normal weight concrete, used in floors or roofs. The elements consist of a top and/or bottom slab and one or more (usually two) ribs; transverse ribs may also be present. Some examples of precast elements

39、 considered in this document are shown in Annex A. Specific requirements for minor floor elements are listed in Annex B. This document covers terminology, performance criteria, tolerances, relevant physical properties, test methods and aspects of transport and erection. This document does not cover
