| Abstract |
Shoes or boots to be tested for dust permeability are fitted with a special flexible insert and mounted in a sealed chamber. The insert is a model of the foot with openings that provide circulation of air within the shoe; it is connected by flexible tubing to a filter and recirculating fan outside the chamber. The mounting for the shoe is connected to a system of levers outside the chamber. This permits the shoe to be repeatedly bent and straightened in imitation of walking. Dust at known concentrations (1-10g/m3) is kept in suspension in the chamber by a fan. After 1h of exposure (30°C deformation, 100cycles/min), the dust collected on the filter is weighed. This weight is a quantitative indicator of the permeability of the tested article. Whereas pull-on half-boots admited 12.4-19.4mg of dust, close-fitting shoes of more elastic leather admitted only 7.4-12.6mg under the same conditions. |
