BS 8313:1997

This standard BS 8313:1997 Code of practice for accommodation of building services in ducts is classified in these ICS categories:

• 91.140.01 Installations in buildings in general

This British Standard gives recommendations for the design, construction, installation and maintenance of ducts in buildings used for the accommodation of services. It also covers enclosures such as ceiling voids and cavities which are used for services but which are not always referred to as ducts.

The recommendations in this standard should also be applied as far as practicable to the adaptation, modification or refurbishment of existing ducts and services within them. Appropriate precautions should be taken in all cases where the existing ducts contain hazardous materials, e.g. asbestos.

This standard covers service ducts attached to the outside of buildings but not service ducts between buildings.

This standard does not cover the design and construction of air or refuse ducts, nor those with `heart units', `packaged plumbing' or `service walls', although parts of it are relevant to them.

This standard does not cover spaces intended mainly for purposes other than the accommodation of services, nor with plant areas such as boiler and calorifier rooms or gas storage areas.

The piping of radioactive substances and the specialist requirements for piping cryogenic liquids are generally outside the scope of this standard.

Recommendations for the design, construction, installation and maintenance of fixed ducts. Also covered are suspended flooring, ceiling voids and cavities.
