Test Methods

Choose the measured behavior before choosing the equipment

ISO 80369 testing decisions begin with the condition being checked: sealing, vacuum leakage, retention force, unscrewing torque, dimensional fit or material response.

Method evidence

Testing methods become practical when the instrument and fixture are visible

Compare the physical tester, fixture or gauge used for each method before confirming the complete test setup.

Select by evidence needed

Choose the method family by the result the buyer must defend

Testing laboratories and QA teams usually know the evidence they need before they know the exact product. Method pages keep equipment, fixture and documentation decisions together.

Leakage or vacuum leakage

Pressure / vacuum channel

Define medium, pressure condition, DUT connection and fixture before selecting Annex B, C or D equipment.

Mechanical retention

Force / torque setup

Separate axial separation, unscrewing torque and overriding so the fixture and result record match the method.

Fit or dimensional inspection

Gauge selection

Confirm sample side, Luer slip/lock condition and certificate expectation before asking for a gauge set.

Method families

Testing tasks grouped by what the laboratory needs to measure

Compare pressure and leakage behavior, mechanical retention, dimensional inspection and material conditioning to identify the equipment and fixtures required for the test.

Leakage setup example

From application standard to fixture and pressure equipment

Leakage and vacuum tests are easier to specify when the standard, connector side, reference interface, fixture and pressure channel are discussed together.
