AbolishedTest methods for aluminium and aluminium alloy foils - Part 9: Determination of hydrophilic property
铝箔试验方法 第9部分：亲水性的测定
Application Summary AI generated
This standard specifies the test method for determining the hydrophilic property of aluminium and aluminium alloy foils, which is critical for evaluating the surface wettability of foils used in applications like air conditioner heat exchangers. It is applied in the manufacturing and quality control of aluminium foil products, particularly where enhanced water spreading and drainage are required to prevent corrosion and improve thermal efficiency. The standard is used by metallurgical laboratories and production facilities to ensure consistent surface treatment performance in HVAC and automotive cooling systems.
