ISO 80369 Leakage Test Equipment Family
Family page for pressure decay, air pressure, and related leakage testing equipment structures.

Use this family page to decide scope before opening individual products
Product families are most useful when they explain the role in the test setup, the applicable standard, likely test method and documents needed for quotation.
Ask KingPo with the family context
Send the product family, connector side, standard part, method requirement, fixture need, quantity and document expectation so the exact item scope can be confirmed.
Prepare family RFQBuild the test chain before choosing the equipment model
ISO 80369 leakage work is not just a tester purchase. The pressure source, measurement channel, reference connector, fixture, DUT support, selected method and documentation scope need to be reviewed together so the equipment can be quoted with the correct interfaces.
- Pressure decay uses a controlled pressure condition and result record.
- Liquid or air leakage methods may need different fixtures and connector support.
- Reference connectors and calibration questions should be included in the RFQ.

Leakage methods lead to different equipment questions
Typical system components
| Pressure source | Stable source selected for the intended method |
|---|---|
| Measurement channel | Pressure, timing and result-recording requirement |
| Fixture | Connector support and DUT positioning |
| Reference connector | Figure item or matched counterpart where applicable |
| Calibration | Discuss pressure channel, reference item and certificate scope |
RFQ checklist
Include the ISO 80369 part, leakage method, connector type, mating counterpart, pressure condition, fixture need, quantity, certificate requirement and whether a complete test setup is preferred.
