ISO 80369 Annex F | Small-Bore Connectors | Axial-Torsion Testing
ISO 80369 is a series of standard test methods intended to evaluate the performance requirements for small-bore connectors for liquids and gases in medical applications. Each of the annexes within the testing standard describe specific test procedures for evaluating the mechanical properties of small-bore connectors. These annexes allow modification to test conditions as necessary for each application.
Annex F – Principle: The security of the connection to an axial pull is determined by applying an axial separation force between the assembled connector under test and the appropriate reference connector. The connection is expected to be maintained.
The standard includes test methods that are derived from ISO 594 with some changes to methods that contained subjective acceptance criteria. It is recommended to read the entire specification in the relevant ISO publication prior to running any of the annexes.

Slip connector:
- Apply an axial force while rotating the slip connector under test in torsion.
- Make sure the rotation does not exceed 90°.
- Apply and hold the axial force in a direction away from the test fixture at the specified rate, at the specified period.
- Verify that connectors have not completely detached at the interface.
Locking connector:
- Apply an axial force while rotating the connector under test in torsion.
- Apply and hold the axial force in a direction away from the test fixture at the specified rate, at the specified period.
- Verify that connectors have not completely detached at the interface.
