This document identifies the requirements, the basic performance criteria and evaluation of conformity for precast linear elements (such as columns, beams and frame elements) made of reinforced or prestressed normal weight concrete, used for the construction of the structures of buildings and other civil engineering works, except bridges. Beams used in conjunction with cast-in-situ concrete topping are also covered. This document covers terminology, performance criteria, tolerances, relevant physical properties, test methods, and aspects of transport and erection. This document does not cover load bearing capacity determined by calculation aided by testing except for spun columns.
