Test Report: SFC Full-Flow Ball-Valve Connector (DN50)

Q: What does test report CLzn2024-01468 prove?

It documents that the Netonx SFC full-flow ball-valve quick disconnect (DN50) passed all 18 tests of an independent accredited lab: visual and dimensional checks, interchangeability, burst and 16-bar working pressure, helium leak rate below 1×10⁻⁶ Pa·m³/s, thermal cycling and thermal shock, storage at −40 °C and 120 °C, 1,000 mating cycles under pressure, spillage per mating, salt spray, vibration, mechanical shock, mold resistance and drop testing.

Q: Who performed the testing and to which standards?

An independent, nationally accredited metrology institute working to ISO/IEC 17025, CNAS-accredited and a CIPM-MRA signatory, in September–November 2024. Test methods followed ISO 18869 and ISO 9227 among others. The full report is available on request from sales@netonx-europe.com.

Q: Why does an independent test report matter for data-center liquid cooling?

Quick disconnects are the leak-critical interface of direct-to-chip cooling loops. Independently verified leak-tightness (helium leak rate below 1×10⁻⁶ Pa·m³/s) and 1,000 pressurized mating cycles give procurement and reliability teams objective evidence when qualifying a second source of UQD-compatible connectors.

Our full-flow ball-valve quick disconnect (self-locking, bidirectional, DN50) was tested by an independent, nationally accredited metrology institute working to ISO/IEC 17025, CNAS-accredited and a CIPM-MRA signatory. All 18 tests were passed.

In short: The Netonx SFC full-flow ball-valve quick disconnect (DN50) passed all 18 tests of an independent, ISO/IEC 17025-accredited and CNAS-recognised lab (report no. CLzn2024-01468, tested 09–11/2024) — including 16 bar working pressure, helium leak rate below 1×10⁻⁶ Pa·m³/s, 96 h salt spray and 1,000 mating cycles under pressure.
