What this method verifies

Select the method before selecting the equipment

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.

Complete test setup

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.

Equipment controls and workflow

Annex D subatmospheric air leakage equipment controls

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.

State whether the buyer needs a setup note, equipment datasheet, result report or certificate discussion.

Laboratory preparation

  • 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.
