In-House Quality Assurance Laboratory Testing Protocols
Real testing benchmarks performed on every batch. We subject water housings, fittings, and filter elements to extreme hydraulic pressure and cycle fatigue to eliminate field failure risks.
500 PSI Hydrostatic Burst Pressure Test Bench
Computerized hydraulic pressure bench ramps complete RO manifolds and 10" filter housing bowls to 500 PSI (3.45 MPa) with continuous hold for 15 minutes. While residential line pressure is typically 40โ80 PSI, our 500 PSI benchmark guarantees a 3.5x safety margin against sudden municipal water hammer spikes.
100,000 Cycle Water Hammer Impulse Fatigue Bench
Servo-controlled high-speed impulse valves subject water filter housings and POM quick fittings to 100,000 continuous cycles of 0 to 150 PSI (0 to 1.0 MPa) pulsation at 30 cycles per minute. This simulates over 10 years of harsh residential water hammer without thread fatigue or fitting separation.
100% Vacuum & Differential Air Decay Leak Detection (0.01 Bar)
Every assembled RO machine manifold undergoes automated dry pneumatic testing before wet testing. High-sensitivity differential pressure sensors detect microscopic joint voids or micro-cracks with 0.01 bar resolution, ensuring 0% factory DOA (Dead on Arrival) rate.
Carbon Iodine Value Titration & Heavy Metal Leachate Testing
UV-Vis spectrophotometer and titration testing verifies Sri Lankan coconut shell activated carbon raw material with iodine value strictly above 1,100 mg/g. Followed by ICP-MS leachate tests on acidic water to verify zero arsenic, cadmium, or lead leaching from sintered carbon blocks.
Automated 12-Station TDS Salt Rejection & Permeate Flow Bench
Continuous 12-station digital RO membrane test bench challenges wound elements with 500 ppm NaCl standard challenge solution at 60 PSI (0.41 MPa) and 25ยฐC. High-accuracy conductivity probes log stabilized rejection rate (≥ 98.5%) and exact GPD permeate flow output.
Pre-Shipment Inspections Welcome (SGS, TUV, Bureau Veritas)
We routinely coordinate with leading international inspection agencies appointed by overseas buyers. Our Cixi facility provides dedicated QA staging offices, calibrated test equipment, and full MES production record access during on-site audits prior to container seal application.
