Flow resistance
Original records cover deionized-water flow-resistance testing in the plug-to-socket direction. Pressure-loss curves were generated across a 0-1 bar range at 1 L/min intervals.
Testing & Quality
UQD testing evidence, presented with clear scope
Panduola Tech presents available test references carefully: current public data covers UQD02 / UQD04 / UQD06 / UQD08 and should not be treated as a universal certification for every series.

Burst pressure
Original burst-pressure records cover three samples per model and show minimum measured values above each stated requirement.

Mechanical life
Original mechanical-life records cover 10 samples per model. All covered models reached at least 5,000 mating cycles and passed pressure leakage checks after testing.

Insertion force
Original insertion-force records cover three samples per model and show maximum measured values within each model's specified mating-force limit.
Burst pressure test
| Model | Minimum burst pressure | Requirement | Safety margin | Result |
|---|---|---|---|---|
| UQD02 | 2730 psi | >= 870 psi / 60 bar | 3.14x | Pass |
| UQD04 | 1590 psi | >= 696 psi / 48 bar | 2.28x | Pass |
| UQD06 | 1452 psi | >= 300 psi / 20.7 bar | 4.84x | Pass |
| UQD08 | 583 psi | >= 300 psi / 20.7 bar | 1.94x | Pass |
Insertion force test
| Model | Maximum insertion force | Requirement | Result |
|---|---|---|---|
| UQD02 | 59.2 N | <= 60 N | Pass |
| UQD04 | 64.4 N | <= 65 N | Pass |
| UQD06 | 83.5 N | <= 90 N | Pass |
| UQD08 | 94.5 N | <= 135 N | Pass |
What the data supports
It is fair to say the covered UQD models have available source records for flow resistance, burst pressure, mechanical life, leakage checks, and insertion force.
It is not appropriate to describe this as universal certification for all series or all customer applications.
Final product choice should still be checked against the drawing, fluid, working pressure, temperature range, and installation requirements.
16 original source PDFs reviewed: four UQD models times four test categories.
Public-facing values are shown under Panduola Tech and standardized for overseas B2B communication.
Original submitting-party names are retained only in private source records and are not used as public website brand claims.
Obvious source-record wording inconsistencies were corrected in the English customer-facing version without changing measured values.
