Quantitative measurements have been made of the smoke production in vision obscuring terms of 5 materials, exposed both in the Fire Propagation Test Apparatus and also in much larger quantities (8 m^2) as the linings of a compartment containing a substantial fire, itself producing little or no smoke. The range of smoke production was very large, extending over three orders of magnitude. Both methods gave similar values for the smoke production of materials producing much smoke, but for materials producing little smoke the large-scale tests registered less smoke than the Fire Propagation test method. Nevertheless there was a strong correlation between the values of smoke production from the two methods under the conditions examined.
