PCT test chamber

IMAGE PLACEHOLDER — Replace with real DX-PCT350 / DX-PCT450 product and open-door photos SATURATED STEAM PRESSURE AGING Select a PCT test chamber from the prescribed method and loaded specimen—not temperature alone. Dexiang DX-PCT350 and DX-PCT450 pressure cooker test chambers generate a saturated-steam environment at elevated temperature and pressure for accelerated moisture-resistance evaluation. Start with the exact PCT method, load envelope, exposure condition and post-test inspection plan before selecting a model. 01 Method and cycle Send the standard or customer procedure, revision, temperature, duration and permitted ramp or exhaust sequence. 02 Loaded specimens Provide dimensions, mass, quantity, orientation, packaging and fixture drawing. 03 Steam access Define spacing and loading so steam can reach the intended surfaces without blocking drainage. 04 Acceptance evidence State calibration, FAT, pressure-vessel documentation and post-test measurements. CONTROL THE EXPOSURE Repeatable PCT testing depends on steam condition, loading and the complete cycle. PCT uses saturated steam—approximately 100% RH—rather than independently adjustable humidity. Temperature and saturated-steam pressure are physically linked, so the agreed procedure must define the condition and pressure basis. Standard range +110 to +132°C. +143°C and +147°C are high-temperature custom configurations, not standard claims. Ramp and dwell Warm-up and pressurization depend on water quantity, load mass, fixture and setpoint. Confirm the guaranteed cycle in the proposal. Controlled completion Automatic pressure release and cooling should follow the method. Premature opening or aggressive exhaust can damage specimens and create misleading results. Water quality Use deionized or distilled water with the purity required by the method and operating manual. Do not use untreated tap water. Specimen loading Keep drainage and steam paths open. Specify tray material, spacing, total mass and any contamination-control requirement. Optional controls Specimen preheating, bias terminals and special fixtures require method, wiring and condensation-risk review.
