Abstract: A method is provided for measuring the local hydraulic permeability, Lpi, of a sub-group of hollow fibres of a bundle of hollow fibres mounted in a tubular casing. The method comprises a step of placing the casing containing the bundle in a vertical position, the lateral opening of the casing being disposed toward the bottom, and sealing the lower end of the casing. A graduated, calibrated tube is applied in a vertical position over a portion of the upper cut surface of the bundle to form a sealed connection there between. A liquid is passed through the lateral opening of the casing at a defined flow rate, and the time required for the liquid to pass from a first graduation to a second graduation of the tube is measured.
