The accumulation of ice on equipment exposed to low temperatures raises major efficiency and safety concerns. To overcome this challenge, various strategies have been developed to create icephobic surfaces. Their characterization typically relies on the measurements of icing delay time (IDT) or ice adhesion strength. However, the absence of standardized testing equipment leads to significant variability, as each research group employs different setups and conditions. This lack of standardization complicates the comparison of results and the evaluation of surface performance. Herein, we describe the development of a new reproducible test bench that allows for simultaneous measurement of ice adhesion strength and IDT under controlled humidity conditions. Results reveal that increasing humidity leads to higher adhesion and lower IDT values. This study highlights the critical influence of humidity and suggests that tests should be performed at low humidity levels in order to accurately assess the intrinsic icephobic properties of surfaces.
暴露在低温环境下的设备上结冰会引发重大的效率和安全问题。为了克服这一挑战，人们开发了各种策略来制造憎冰表面。其特性表征通常依赖于结冰延迟时间（IDT）或冰附着力强度的测量。然而，由于每个研究小组使用不同的装置和条件，缺乏标准化的测试设备导致了显著的变异性。这种缺乏标准化的情况使得结果的比较和表面性能的评估变得复杂。在此，我们描述了一种新型可重复测试台的开发，该测试台能够在受控湿度条件下同时测量冰附着力强度和IDT。结果表明，湿度增加会导致附着力升高和IDT值降低。本研究突出了湿度的关键影响，并建议应在低湿度水平下进行测试，以便准确评估表面的固有憎冰特性。
