Withdrawn Historic British Standards - CP3 (Roof imposed loads)

Withdrawn Historic British Standards - CP3 (Roof imposed loads)

Withdrawn Historic British Standards - CP3 (Roof imposed loads)

Hello all,

I'm trying to track down a copy of CP3 Chapter V part 1 - ('Code of basic data for the design of buildings. Loading - Dead and imposed loads').

However unfortunately I can't find anything.

Does anyone here happen to have a pdf, or any alternative documents / books which would contain information on the imposed load allowances? (not wind loading)

(As the code is withdrawn a very long time ago I assume there's no issues with copyright etc.)

Thanks in advance.

Dear DArmst264 (Structural);

Are you looking for BS 6399-3 , Part 3: Code of practice for imposed roof loads ? I have the copy BS 6399-3, but chapter nos are not the same with yours.


He is like a man building a house, who dug deep and laid the foundation on the rock. And when the flood arose, the stream beat vehemently against that house, and could not shake it, for it was founded on the rock..

Luke 6:48

Might help, from a 2007 posting - thread507-200556: live load on "british code" building 1951
