Liquid-cooled systems must undergo air-tightness testing

Liquid-Cooled Leak Testing: With the National Standard Set to Take Effect in 2026, How Should Companies Establish a Mass Production Quality Inspection System?

This article outlines the key points of airtightness testing for liquid-cooled data centers: The new national standard set to take effect in 2026 only establishes a framework, with leakage rates to be determined by the product manufacturer; it compares the applicable scenarios for four testing methods—direct pressure, differential pressure, flow rate, and helium leak testing; it points out that fluctuations in results are often due to system factors such as test fixtures and temperature rather than the instruments themselves; It emphasizes that companies should establish their own testing specification matrices to translate standards into stable, traceable mass-production testing capabilities.
