Quality Control

Gas stove quality control adheres to factory standards through multi-stage protocols:​

-Incoming Material Inspection​
Validate compliance of key components against factory specs: Gas valves must meet 30kPa pressure resistance per certificates; pipelines undergo 0.6MPa air pressure testing for 30 minutes with zero pressure drop. Burners are checked for dimensional accuracy (±0.5mm) via calipers to ensure fit with combustion chambers.​

-Assembly Stage Monitoring​
At critical assembly steps: Ignition modules are calibrated to achieve spark within 3 seconds; flame sensors must trigger shutdown within 60 seconds of flame loss. Gas line connections are torque-tested (25-30N·m) to prevent leaks, with visual checks for proper sealant application.​

-Gas Ventilation Testing​
Conduct full-system pressure tests at 2.25kPa (1.5× working pressure) for 60 minutes, ensuring no pressure decay. Verify combustion efficiency via flue gas analysis: CO emissions < 0.05% and thermal efficiency ≥ 63%. Test ignition 50 consecutive times to confirm reliability.​
Packaging Verification​.

-Packaging Verification​
Ensure EPE foam cushioning covers sharp edges (burners, valve knobs) with ≥5mm thickness. Check instruction manuals include gas safety warnings (e.g., "Do not use in unventilated spaces") and CE/ISO markings. Cartons undergo drop tests (1.2m height) to validate structural integrity, preventing transit damage.
