Fittes, D.W., 1958. THE EFFECT OF REPEATED CHARGING AMD DRYING ON THE PERCOLATION OF WATER THROUGH UNLINED FIRE HOSES. Fire Research Notes 343
The percolation from unlined fire hose was found to increase with repeated charging and drying, although the amount of increase varied somewhat between the different makes of hose tested. The percolation from new fire hose was found to give some guide to its behaviour in subsequent use. The acceptance limits for the percolation from new unlined fire hose, as specified in B.S. 2599: 1955, were examined and possible adjustments are indicated.
