Scope

This document specifies the properties and characteristics of typical vertical joints between two prefabricated concrete external wall components irrespective of whether these joints coincide with joints between the external wall and an internal wall or column. However, the characteristics of joints which are involved in the structural behaviour of buildings are not specified in this International Standard. This International Standard is applicable to all public or private buildings, used as dwellings, offices, educational or hospital premises.
