ISO 80369-20 Annex B/C Leakage Method
Compare ISO 80369-20 Annex B pressure-decay testing with Annex C positive-pressure liquid leakage, including equipment, connectors, fixtures and report requirements.

Select the method before selecting the equipment
Leakage by pressure decay follows ISO 80369-20 Annex B. KingPo also has a documented Annex B/C pressure and positive-pressure liquid leakage tester, so this method page separates Annex B pressure-decay planning from Annex C liquid workflow support.
The public Figure B.1 apparatus reference clarifies the pressure source, measurement, test-volume and reference-connector roles; KingPo operating material supports the equipment workflow, while final settings and acceptance criteria remain controlled.
Build the measurement chain around the connector
Identify the device under test, select the correct mating or reference interface, support it with the required fixture, connect the measurement channel, and define the result record before requesting equipment.

Annex B/C pressure and liquid leakage equipment controls
KingPo supplied material identifies this tester for ISO80369-20 Annex B and Annex C. The manual names live pressure, test time, P1, curve display, leakage-rate calculation fields and Print report controls; the liquid workflow uses the liquid tank, sample connection and AIR OUTLET path.
- Power supply: 220V 50Hz; one test station.
- Pressure range: 0-600 kPa; accuracy: +/-0.25%; settable time: 0-9999 s.
- Named calculation inputs include starting pressure, pressure change, test period and volume from valve to specimen.
Confirm the sample, setup and required records
Ask for the expected curve, result record, report printout, certificate wording and whether the quality team needs the controlled operation manual.
Laboratory preparation
- Confirm that the selected method is Annex B pressure decay, not Annex C positive-pressure liquid leakage or Annex D subatmospheric air leakage.
- Identify the connector under test, matching reference connector, pressure source, pressure measurement channel, test volume and fixture support.
- For the separate KingPo Annex B/C documented tester, the pressure workflow includes installing the sample, setting test time, pressure and sample volume before starting the test.
- For the positive-pressure liquid workflow, prepare the liquid tank connection, AIR OUTLET line, sample outlet blocking step and valve sequence before starting the test.
