Batareya balandligi simulyatsiya sinov kamerasi

It is a low-pressure chamber that reproduces reduced atmospheric pressure so cells and batteries can be evaluated for leakage, venting, rupture and other effects associated with transport at altitude. The DR-D203 controls pressure from 0.5 to 100 kPa.

Its pressure range includes the 11.6 kPa-or-less condition used for T.1 and its timer supports the required exposure duration. The laboratory remains responsible for the applicable edition, specimen preparation, ambient-temperature condition, calibrated measurement, acceptance evaluation and complete test record.

No. Altitude simulation is only T.1. Complete UN 38.3 conformity depends on all tests applicable to the cell or battery type, the prescribed sequence and compliant documentation.

No verified controlled temperature range is listed for the standard DR-D203 configuration. It is presented here as a low-pressure chamber. Ask for a temperature-altitude chamber if pressure and temperature must be controlled simultaneously.

The workspace is 400 × 400 × 400 mm with two shelves. Usable capacity depends on specimen clearance, cable routing and safety spacing, so provide sample dimensions and quantity before ordering.

Only when suitable sealed electrical feedthroughs, monitoring hardware and risk controls are included in the approved configuration. Do not route temporary cables through the door seal.

Set an interval and permissible error based on the governing procedure and laboratory quality system. Verification should use a suitable traceable reference; request the required calibration documentation when ordering.

Provide chemistry, state of charge, total stored energy, specimen condition, expected failure modes and the facility's ventilation, detection and emergency-response requirements. These details determine whether additional ports, exhaust, detection or protective functions are needed.
