Web28 jan. 2024 · Helium Sniff Testing During a helium sniff test, the pressure vessel being evaluated is pressurized with helium gas. Once the desired pressure is reached, a special piece of equipment known as a helium sniffer is moved around the vessel. WebTo detect tears or pinholes in the bag, a helium leak test was evaluated. First, a simple experimental model of helium leakage from bags was established. In the model, a pinhole was made in a film disk of the aluminum laminate or polyethylene material used for the inner and outer bags.
