| Abstract |
In order to make available a consistent set of information about the fibre diameter distribution in man-made vitreous fibre (MMVF) products, the length-weighted fibre diameter distribution in 22 samples of glass wool, rock and slag wool, refractory ceramic fibre, and special purpose fibre insulation, from 11 different manufacturers, was measured. All of the samples were measured by the same procedures using light microscopy (LM), scanning electron microscopy (SEM), and gas adsorption (the BET method). The diameters were neither approximately normally nor log normally distributed, with arithmetic standard deviations typically 50-100% of the arithmetic mean. The geometric mean diameter was usually significantly smaller than the arithmetic mean diameter (1-8µm for glass and 2-5µm for rock and slag); the length-weighted median diameter lay between these two means. There was good agreement between the various means and standard deviations measured by LM and by SEM. The BET-measured fibre specific surface area agreed well with that calculated from the microscopically measured diameters. |
