IGN 4-11-02 Issue 1 Revised bedding factors for vitrified clay drains and sewers

This Information and Guidance Note contains advice relating to revised bedding factors for vitrified clay drains and sewers. At the time of publication it was the intention to pursue the principle of common bedding factors for all rigid pipes and it was envisaged that work in progress would enable advice to be given for other rigid pipe materials in pursuance of this aim. This interim Guidance Note therefore contains advice which it was hoped would be incorporated into guidance relating to bedding factors for all rigid pipes at an appropriate time.

Caveats

One or more ‘Common Editorial Caveats’ apply – see ‘WIS & IGN Library / Navigation & Caveats’ for details.

Subject to further discussion with stakeholders, the Standards Board proposes to archive this IGN on the basis of its replacement by BS 9295: 2020 A guide to structural design of buried pipes.
