A method for inspecting a defect of a hollow fiber porous membrane having substantially uniform, continuous inner hollow portions comprises steps for introducing a part of the hollow fiber porous membrane into an irradiation chamber, for irradiating the hollow fiber porous membrane with light from the outside in the irradiation chamber, and for detecting light exiting the hollow fiber porous membrane on the outside of the irradiation chamber.
La présente invention concerne un procédé de contrôle des défauts d'une membrane poreuse en fibres creuses comportant des portions creuses intérieures, continues et essentiellement homogènes. Le procédé comprend les étapes consistant à introduire une partie de la membrane poreuse en fibres creuses dans une chambre d'exposition, afin d'exposer la membrane poreuse en fibres creuses à de la lumière en provenance de l'extérieur de la chambre d'exposition et de détecter la lumière sortant de la membrane poreuse en fibres creuses à l'extérieur de la chambre d'exposition.
