Government prepares 'major' review of Building Regulations


There was an interesting article in one of the online construction papers earlier this week. It was suggested that the test they carried out on the first batch of 80-odd buildings' cladding samples was a calorific test in pure oxygen, and not a recognised 'construction industry' test. (All of these buildings failed their test and this heightened panic) A calorific test, if I understand it correctly, is intended to determine basically how much 'fuel' is in the sample. They weigh a sample, burn it in pure oxygen *, heat some water with it and measure the temperature rise. This of course doesn't have much to do with combustibility or non-combustibility at all. * Clean air is approx. 21% oxygen You could do the same test with a cheese sandwich and find out just about as much.
