does BS stand for bull sh!tBS 5975 with reference to BS EN 12811 is what I have been told.
The standards were based on data from Building Research Establishment (UK) www.bre.co,uk,--- BRE Digest 284, Wind loads on canopy roofs. BRE Digest 346 Parts 1-8, assessment of wind loads, BRE Digest 436 Parts 1-3,Wind loads on buildings. Dont confess to understand them, but would not the same data be used in the UK.BS EN 12811 is the same as IS EN 12811, both European standards.I think it was the change in European wind codes.
