  • Patent number: 7131316
    Abstract: A dry testing method for a glove (10) made with an air permeable, waterproof material (16). The stem (22) of a tee fitting (24) is connected to an air pump (20) source. A mouth (30) of the glove is tightly attached to one end (32) of the fitting so no air can escape through the mouth. An airflow meter (26) or air pressure gauge connects to another end (28) of the fitting. When the air pump is running, the glove inflates with air and a backpressure is created. The flow meter is read to determine the backpressure level in the inflated glove, the glove being accepted if the meter registers at least a predetermined value indicating the glove does not leak water, but the glove being rejected if the meter reading is less than the predetermined value.
