  • Patent number: 5097697
    Abstract: An automated condom airburst testing apparatus is disclosed which utilizes a deformable elastomeric ring which operates, in conjunction with a collar, to form a temporary, yet secure, airtight seal around the flexible condom membrane. A multiple stage series regulated inflation gas supply system provides a substantially fluctuation-free flow of gas to inflate a condom. A differential pressure measuring system, which is separate from the inflation supply system, determines the difference between the pressure within the condom membrane and atmosphere. The apparatus also provides the maximum pressure and volume within the condom just before the condom is destroyed by bursting.
