摘要： A method and apparatus for the leak testing of one or more filters, which requires minimum space, and which comprises a housing (12) adapted to sealably mount the filters (30), supply pipes (40, 41) for introducing DOP particles within the housing and immediately upstream of each of the filters, and a restriction member (54) mounted in the housing upstream of each filter and downstream of the point at which the DOP is introduced. The member (54) may be selectively positioned to assume an operative position transverse to the airstream wherein it acts to condense and mix the airstream and DOP and then disperse the mixture over the full frontal area of the adjacent filter, or a non-operative position wherein the member is substantially withdrawn from the airstream. A sampling device (70) is also mounted downstream of each filter for monitoring the airstream to detect DOP particles, and thereby permit a determination as to whether any of the particles are leaking through or around the filter.
