DEVICE FOR TESTING THE POROSITY OF THIN RUBBER PRODUCTS

摘要

The proposal is for a device for testing the porosity of dielectric films, especially thin rubber products like condoms (2), with a cover support over which the rubber product is stretched and one or more external electrodes (5), where the cover support (1) and the external electrodes (5) are connected to a voltage source and an electrical measuring instrument, in which the external electrodes (5) are punctiform, the external electrodes (5) and the cover support (1) can be moved in relation to one another so that the skin of the rubber product can be successively contacted by the external electrodes (5), the measuring instrument measures the current flow at each individual electrode and indicates a defect at a measurement which corresponds to a reference value for the material-free state without the presence of a rubber product.
