a VT is measured by means of a pressure sensor at the test lung, where V T = C x (P max ), and VT is the volume delivered to the test lung C is the isothermal compliance of the test lung Pmax is the maximum pressure measured in the test lung b The accuracy for C and R applies over the ranges of the measured parameters. | |||
Iso 80601-2-12 Test Conditions For Acoustic Tests Test Lung. ISO 80601-2-12 — Medical electrical equipment — Part 2-12: particular requirements for basic safety and essential performance of critical care ventilators. Kingpo machines reference connectors and gauges in-house from hardened steel, inspects them against the figure before despatch and supplies them with a calibration certificate.
ISO 80601-2-12 sets the conditions for acoustic tests, including the test lung used as a load.

Reference connectors are inspection tools. Overriding tests and repeated axial-load tests wear them by design — plan replacement against test cycles.
Annex C (and the equivalent annexes in the other parts) assigns one figure per reference connector, and each figure is certified for a specific set of tests. Picking the wrong one is the most common specification error in this category: the connectors look almost identical, but a figure that is certified for leakage is not the one you use for separation from axial load. Order against the figure number in your test protocol, not against the photograph.
A reference connector is not a complete test system. Leakage, sub-atmospheric air leakage and separation-force tests need pressure, vacuum or force applied through ISO 80369-20 test apparatus. It is also not a simple go/no-go dimensional gauge: for a quick fit check on a conical fitting you want a plug gauge or a ring gauge, not a reference connector.
Only the tests the figure is certified for. Different figures are machined to different limits and, in some cases, to different materials, because the test loads differ.
Yes. Kingpo builds the ISO 80369-20 apparatus — leakage, sub-atmospheric air leakage, separation force and unscrewing torque — alongside the reference connectors.
Yes, and we re-calibrate reference connectors you already hold.
