ABSTRACT:
A method and device (10) for testing condoms, the device (10) comprises a perforated, elongated plastic, cylindrical member (12) having a head (14) at one end thereof, a body (16) and a base (18) at the other end thereof. Fitable into the hollow interior of cylindrical member (12) is a plunger assembly (30) with a piston (78) thereon. Perforations (20) in the body (16) of the cylindrical member (12) provide communication with a sleeve (28) in which the piston (78) rides. A condom is unrolled over cylindrical member (12) and sealed air-tight to the base (18) thereof. Pumping the piston (78) inflates the condom where it can be inspected for perforations, tears, and porosity. A flap valve (35) in the piston (78) allows air in the condom to escape through the perforations (20) and through a whistle means (42) to provide an audio signal whose pitch is a function of velocity of air through the signal and thus indicative of the porosity of the condom membrane.
