Specifies requirements for fabricated drainage stack units, manufactured from steel and galvanised after fabrication. Coverage includes: materials, fabrication, jointing, inspection, marking, assembly of units, and dimensions and weights. Also gives definitions, tables and diagrams.

This British Standard specifies requirements for prefabricated drainage stack units, manufactured from steel and galvanized after fabrication.

These units are for use above ground, in plumbing systems for wastewater and rainwater; to include pipework within or external to a building, including basements, but excluding pipework which enters the ground.
