A battery pack leakage detection system and detection method are provided. The system includes a test container, a gas filling subsystem, a gas stirring subsystem and a test analysis subsystem. The method can test the sealing performance of the battery pack under the atmospheric pressure, so that the battery pack can meet the corresponding sealing grade requirements of IP67 and IP68. The method not only solves the problem that the traditional gas detection method cannot meet the test requirements of IP67 and IP68 due to insufficient measurement precision, but also solves the problem that the traditional vacuum helium detection method will damage the battery cells in the battery pack.

A method and system for determining an integrity of a container, including obtaining a pressure inside a container by producing, filling and/or sealing a container using heat or at cold conditions. Transmitting a light signal through a headspace of the container and determining, based on the transmitted light signal being detected, the integrity of the container.

A fluid evacuation apparatus comprising a platform which is configured to receive at least one component. The fluid evacuation apparatus further comprising a cover comprising a polymeric membrane, the cover configured to be placed over the at least one component and configured to sealingly engage the platform, thereby forming a chamber which defines a chamber volume. The fluid evacuation apparatus further comprising a pump connected to the apparatus and configured to pump fluid out of the chamber volume.

A fitting assembly includes a fitting comprising a housing and a connector assembly arranged within the housing. The connector assembly comprising a hollow interior and configured to be movable between an unactuated position and an actuated position. In the actuated position, the connector assembly is connectable to a pipe receivable within the hollow interior. An adapter coupled to the fitting includes a biasing mechanism configured to bias the connector assembly from the actuated position to the unactuated position.

A leak test machine for a vehicle rim includes a base that supports a lower sealing element receiving a first edge of the vehicle rim, and a closing element translatable along a translation direction. In an open configuration the closing element is not engaged with the base and allows insertion of the vehicle rim on the lower sealing element. In a closed configuration the closing element sealingly engages the base to define an outer chamber completely surrounding the vehicle rim. An upper sealing group sealingly engages the vehicle rim on an outer edge opposite to the first edge to define an inner chamber. A sealing group translation device moves the upper sealing group along the translation direction, the upper sealing group being supported in an articulated manner by the sealing group translation device to allow rotation of the upper sealing group around an axis incident to the translation direction.

A gas detection apparatus for cell module assemblies accurately and rapidly detects a damaged cell of a cell module assembly and the damaged position of the damaged cell. The gas detection apparatus includes a gas detection chamber configured to receive a cell module assembly; and a sliding die configured to be movable to the lower part of the gas detection chamber in the state in which the cell module assembly is disposed at the upper end thereof. The gas detection apparatus further includes a gas sensor provided in the gas detection chamber, the gas sensor including a plurality of gas sensors disposed so as to correspond to positions of cells of the cell module assembly. A gas detection method for cell module assemblies uses the gas detection apparatus for cell module assemblies.

The invention concerns a detection method for checking sealed product packages for leaks, characterized in that it comprises the following steps: at least one previously sealed product (2) is placed in an air, nitrogen, or oxygen atmosphere, in a chamber (3) (step 101), the pressure in the chamber (3) is lowered to a secondary vacuum pressure below 10.sup.−1 mbar and, while continuing the secondary vacuum pumping of the chamber (3), the gases contained in the chamber are ionized to monitor the change in the chamber (3) of the concentration of at least one gaseous species of the gas volume contained within the sealed product (2) chosen from among nitrogen, oxygen, or argon, by analysis by optical emission or mass spectrometry (step 102).

Provided is a method for manufacturing a sealed battery, capable of reducing an erroneous determination rate in a leak testing step. The method including the leak testing step for detecting leak of a detection gas introduced into a battery case, includes: an introducing step for introducing the detection gas into the battery case which is temporarily sealed by covering the battery case; and an adjusting step for adjusting at least one of the pressure inside the battery case temporarily sealed and the pressure outside the battery case so that the pressure inside the battery case into which the detection gas has been introduced is lower than the pressure outside the battery case.

The present invention relates to a displacement device, DD, for providing a displacement of a syringe closure system for a syringe relative to the syringe, a testing device, TD, and a method for leakage testing of a connection of a syringe closure system for a syringe with the syringe.

A method for detecting leakages of fluids from sealed containers includes defining a detection zone in which a sealed container will be placed, putting the detection zone in communication with at least one gas sensor through at least one duct, introducing a flushing gas into the detection zone through the at least one duct, placing a container in the detection zone, sucking gases from the detection zone through the duct and transferring them to the sensor for ascertaining the presence of a gas leakage in the container.
