UQD Testing Evidence
Source records reviewed for UQD02 / UQD04 / UQD06 / UQD08.
2025-11-17
Burst pressure
Original burst-pressure records cover three samples per model and show minimum measured values above each stated requirement.
2026-04-13
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.
