Describes product performance requirements for spacers and chairs sufficient to achieve and maintain cover to reinforcement in, in situ reinforced concrete members subject to normal construction loads when used in accordance with BS 7973-2.

This part of this British Standard specifies product performance requirements for spacers and chairs sufficient to achieve and maintain cover to reinforcement in in situ reinforced concrete members subject to normal construction loads when used in accordance with BS 7973-2.

NOTE Where appropriate, the basic principles can be applied to precast concrete or proprietary systems.

Product requirements for spacers and chairs include their dimensions, identification, point load strength, permanent deflection after loading, stability and fixity.
