Name: HF-6210A Low Pressure Test Chamber
Function and Purpose:
Objective:
Applicable Standards:
Low pressure equipment, also known as battery low pressure (high altitude) simulation test, performs all sample tests under a negative pressure of 11.6 kPa (1.68 psi).
High altitude simulation test where all samples are tested under low pressure conditions. The final test results require that batteries must not explode or catch fire. Additionally, batteries must not emit smoke or leak liquid. The battery protection valve must remain intact.
UN 38.3, UL1642, UL2054, IEC61960, IEC62133, GB/T 18287-2013, GB31241-2014 testing standards.

Structural Features of the Test Chamber:
The outer chamber is made of high-quality cold-rolled steel plate with electrostatic powder coating, providing a hard, durable surface with excellent rust resistance.
The working chamber (inner box) is made of high-quality stainless steel with rounded corners, smooth surface, easy to clean.
Between the outer chamber and working chamber is filled with ultra-fine glass wool insulation material.
The chamber door is tempered glass, allowing clear observation inside.
A rubber sealing ring is installed between the working chamber and glass door to ensure high vacuum inside.
Vertical structure: operation panel and vacuum pump are located at the upper part, low pressure chamber at the lower part.
Uses PLC control combined with a high-definition sensitive touchscreen operation mode.
Main Technical Parameters:
Pressure range: 3 to 100 Kpa (adjustable), commonly used test pressure is 11.6 Kpa.
Temperature range: room temperature.
Units: Kpa (or Bar).
Inner chamber dimensions: W1000 × D1500 × H1000 mm.
Outer chamber dimensions: W1250 × D1800 × H1560 mm.
Inner chamber material: SUS 304 stainless steel with reinforcement treatment.
Outer chamber material: cold-rolled steel plate with reinforcement treatment and fine powder coating.
Base equipped with universal wheels.
Viewing window: tempered glass with explosion-proof film and LED cold light illumination for easy observation during testing.
Control method: high-definition sensitive touchscreen with proprietary software developed by Ligao.
Vacuum display: digital vacuum gauge with precise vacuum level display, easy to set vacuum level.
Vacuum degree: 1.3 Kpa (vacuum gauge reading -100.0 Kpa).
Note: The atmospheric pressure inside the chamber is normally 101.325 Kpa. To achieve the low pressure of 11.6 Kpa inside, about 89.7 Kpa must be evacuated. Since the gauge shows negative pressure, a reading of -89.7 Kpa corresponds to 11.6 Kpa inside the chamber.
Pressure fluctuation: ≤ 5%.
