ISO 80369-20 Annex D Subatmospheric Pressure Leakage
Use this page to prepare ISO 80369 connector, product, standard and RFQ context for KingPo review.
How this method is used in selection
Subatmospheric-pressure air leakage uses the KingPo ISO80369-20 Annex D tester. KingPo supplied documentation identifies a 220V 50Hz, 1-station tester with 0 to -90 kPa pressure range, +/-0.25% accuracy and 0-9999 s settable test time.
ISO 80369-20 Annex D relationship is supported by KingPo supplied operating material.

Owner manual evidence: Annex D subatmospheric air leakage tester
KingPo supplied Annex D documentation describes the reduced-pressure air leakage workflow: stable desktop placement, power connection, touch-screen Pressure function, sample installation, time/pressure/sample-volume setup, Start command and pressure valve adjustment.
- Power supply: 220V 50Hz; one test station.
- Pressure range: 0 to -90 kPa; accuracy: +/-0.25%; settable time: 0-9999 s.
- The sample-volume note includes the sample plus internal pipe volume, recorded as 1.57 cm3 in the supplied material.
Prepare the connector, fixture and document context
State whether the buyer needs a setup note, equipment datasheet, result report or certificate discussion.
Typical setup questions
- Confirm that the requested method is Annex D subatmospheric air leakage rather than Annex B/C pressure or liquid leakage.
- Place the device on a stable desktop, connect power, turn on the power switch and select the touch-screen Pressure function.
- Install the sample, set test time, test pressure and sample volume, start the test and adjust the air pressure valve to the set value.
- KingPo supplied documentation names leakage-rate fields, pressure change, test period, curve display and print report controls.
