前言
国际标准化组织 (国际标准化组织) 是国家标准机构的全球联盟 (ISO成员机构). 国际标准的制定通常通过ISO技术委员会进行. 对已成立技术委员会的主题感兴趣的每个成员机构都有权在委员会中派代表参加. 与标准化组织联络的政府和非政府国际组织也参与了这项工作. ISO 与国际电工委员会密切合作 (国际电工委员会) 关于电气标准化的所有问题.

国际标准是根据第 6 部分给出的规则起草的。 2 ISO/IEC 指令的.

技术委员会的主要任务是制定国际标准. 技术委员会通过的国际标准草案将分发给成员机构进行投票. 作为国际标准的出版至少需要获得批准 75% 成员机构数量.

介绍
This standard describes two methods for determining the ability of paints or other organic coatings applied to metal substrates to withstand cathodic debonding. These methods can also provide a basis for comparing specific coatings. The test conditions are more severe than those that might be encountered under normal conditions and therefore may accelerate coating failure. Testing is recommended for at least 26 周, so these methods are not suitable as a means of achieving quality control.

The method is applicable to coatings used to protect ships and structures exposed to seawater. Method A is based on procedures developed and evaluated by the COIPM (International Standing Committee for the Protection of Malin Materials).

Test results may be influenced not only by the performance of the coating system under test, 还取决于基材的性质和制备, the method of application of the coating system, 和其他因素.

1 范围
This standard describes two methods for determining the ability of paints or other organic coatings applied to metal substrates to withstand cathodic debonding when the surface coating may contain or develop discontinuities. These methods are suitable for coatings that are exposed to Marine water, such as those applied to ships or Marine structures. They are not suitable for assessing the ability of coatings to withstand cathodic debonding on terrestrial structures.

Method A involves the use of a cathodic protection circuit where the electrode potential of the test substrate is controlled by a constant potential.

Method B involves the use of a sacrificial anode attached to the test substrate. This reflects the practical method of cathodic protection commonly used on ships.

3 术语和定义
就本文件而言, 以下术语和定义适用.

3.1 Cathode debonding
Failure of bonding between the coating and the metal surface, which is directly attributable to cathodic protection conditions and is often caused by defects in the coating system, such as accidental damage, imperfect application, or excessive coating permeability
