This European Standard is one of a series of product standards for precast concrete products. For common aspects of concrete products, reference is made to EN 13369, from which also the relevant
27、 requirements of the EN 206-1 are taken. The references to EN 13369 by CEN/TC 229 product standards are intended to make them homogeneous and to avoid repetitions of similar requirements. !Eurocodes are taken as a common reference for design aspects.
