Scope

This standard gives specifications for materials, production, properties, requirements and methods of testing for precast concrete monolithic stairs, and for precast concrete elements (e.g. individual steps) used to make reinforced and/or prestressed concrete stairs.
This standard is applicable to structural stairs for indoor or outdoor use.
This standard covers precast concrete stairs and associated landings of monolithic design or constructed from individual steps supported by beams or columns. Supporting elements may include in situ concrete.
This standard covers terminology, performance criteria, verification methods, tolerances, relevant physical properties, special test methods and specific aspects of transport, erection and connection.
Geometrical properties related to functionality of stairs are not covered by this standard and can be found in National regulations or local practice.
Precast concrete stairs are classified into two main product families :
 monolithic stairs constructed from precast concrete components consisting of flights, landings or a combination of these. They may include vertical supporting elements ;
 stairs constructed from individual steps, whether load bearing or not, assembled on site with, for example, carriages or a central column.
Their shape may be straight or winding.
Stairs may incorporate parapets (on one or both sides) and landings.
Stairs may have simple bearings (e.g. on corbels, walls or beams), bolted connections or they may be connected with reinforcement and in situ concrete.
The surfaces of the precast elements may be exposed or covered by finishes.
