标准范围

ISO 15711:2003描述了两种方法，用于确定当表面涂层可能包含或出现不连续性时，应用于金属基材的油漆或其他有机涂层承受阴极剥离的能力。这些方法适用于暴露在海水中的涂层，例如用于船舶或海洋结构物的涂层。它们不适用于评估涂层承受陆基结构上阴极剥离的能力。方法A涉及使用阴极保护电路，通过该电路，对测试基板的电极电位进行恒电位控制。方法B涉及使用连接到测试基板的牺牲阳极。这反映了船舶上常用的阴极保护实用方法。

ISO 15711:2003 describes two methods for determining the ability of paint, or other organic coatings, applied to metallic substrates to withstand cathodic disbonding when the surface coating may contain or develop discontinuities. The methods are applicable to coatings that are exposed to sea water, such as those applied to ships or marine structures. They are not suitable for the assessment of the ability of coatings to withstand cathodic disbonding on land-based structures.Method A involves the use of a cathodic protection circuit, whereby the electrode potential of the test substrates is controlled potentiostatically.Method B involves the use of sacrificial anodes attached to the test substrates. This reflects the practical method of cathodic protection commonly used on ships.
