BS EN 14843 is one of a series of product standards for precast concrete products. BS EN 14843 is applicable to structural stairs for indoor or outdoor use.
BS EN 14843 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.
BS EN 14843 covers terminology, performance criteria, verification methods, tolerances, relevant physical properties, special test methods and specific aspects of transport, erection and connection.
Note: Geometrical properties related to the functionality of stairs are not covered by BS EN 14843 and can be found in National regulations or local practice.
BS EN 14843 on precast concrete stairs is useful for:
Precast concrete products are designed and manufactured in a cement factory. They can be of standard dimensions or can be manufactured as per the project’s requirements. Since these products are made separately from the construction project, they need to meet the performance criteria.
BS EN 14843 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.
Overall, these guidelines of BS EN 14843 help you to produce or install quality precast concrete stairs in your construction projects.EN 14843:2007
