Testing of vacuum bags used in manufacturing of complex co-cure composite structures provides leak detection that allows an operator to identify leaks within a custom vacuum bag without further damaging the bag, such as by cutting vacuum ports into the bag. Such leak detection can allow the operator to find and repair the leak or, if not repairable or at a location of the bag for which repair is not feasible, take other corrective action.

An improved leakage testing device for attachment to a flexible wall of an item to be tested is provided with a film (4) that limits a hollow chamber (1) on the outer side of the item to be tested and with a leakage (2), said film (4) being designed to adhere to the item to be tested.

A test system and a corresponding method for testing the seal of a glove which is installed in a port of an isolator, including a test disc which can be connected in a hermetically sealed fashion to the port. The glove and test disc define a sealed glove volume which can be placed under excess pressure. The test disc has a pressure-measuring device with a microprocessor and a memory for recording and storing a pressure profile in the glove volume and a data interface. The glove and port have identification elements which are read by a reading device of the test disc and information concerning the pressure profile along with the identities of the glove and port are transmitted wirelessly to an evaluation unit which estimates and records a residual period of use of the glove. A plurality of gloves in ports can be tested simultaneously.

Method and machine for generating packages from a continuous film. In the method, the quality of the seals formed when generating packages on the film is furthermore verified, and to that end, a chamber is closed around an area of a film tube comprising an actuation area, a transverse cut and a transverse seal on each side of the transverse cut being generated in the actuation area. For the verification, pressure in the chamber is reduced, a property of the fluid present in the chamber or in the part of the tube present in the chamber is detected, and the quality of at least one of the seals present in the chamber is determined depending on the detection.

A method for maintaining at least one protective suit. The method comprises connecting at least one maintenance adapter in a detachable and sealing manner to at least one aperture of the protective suit. Cleaning and disinfecting is passed through the maintenance adapter and into the inside of the protective suit and is subsequently discharged. Drying gas is then passed through the maintenance adapter into the inside of the protective suit and subsequently discharged.

A system which evaluates a reliability of piping connections with gaskets is provided. A gasket connection reliability evaluation system includes: a measurement value acquisition unit configured to acquire a measurement value obtained through measurement by a sensor provided in a system including piping connections with gaskets; a simulation unit configured to simulate a behavior of a fluid flowing through the system on the basis of the measurement value and calculate a state quantity relating to the fluid; a loading analysis unit configured to analyze a loading applied to each of the gaskets on the basis of the measurement value and the state quantity and calculate a connection index of the gasket; a fatigue analysis unit configured to analyze a fatigue state of the gasket on the basis of the measurement value, the state quantity, the loading applied to the gasket, and a specifications and condition of the gasket connection and calculate a deterioration index of the gasket; and a reliability evaluation unit configured to calculate a reliability of the gasket on the basis of the measurement value, the state quantity, the connection index, the deterioration index, and a predetermined reliability evaluation model.

A facemask configured to be used by multiple sized/shaped heads can include a primary, a secondary and a tertiary seal. In some embodiments, the primary seal is contact with the nose and cheek regions; the secondary seal is in contact with the chin region; and the tertiary seal is in contact with the cheek and chin regions. In some embodiments, the tertiary seal extends inwardly and outwardly when applied to the face. In some embodiments, the mask includes test scissors.
