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.

The second edition eliminates and replaces the technically revised first edition (国际标准化组织 11998:1998). 主要变化是:

– The definitions of trip length and scrubbing cycle have been changed and a new term scrubbing length has been introduced;

— The coating dry film density determination method specified in Appendix A has been replaced by the new method.

介绍
As stated in the introduction, this international standard is a revised version of ISO 11998:1998. The use and application of the standard has now been established worldwide and improved procedures/equipment have been proposed. The CEN/ISO Joint Working Group has approved the use of new grinding pads (different from those specified in 6.5) for inter-laboratory testing. The results of the tests are expected to be published by the end of 2006 and an early revision of the standard may begin.

1 范围
The ability of the coating to withstand wear caused by repeated cleaning operations and to withstand the penetration of fouling agents is an important consideration from a practical point of view as well as from the point of view of comparing and rating such coatings. This standard describes an accelerated method for determining resistance to wet scrubbing. With regard to the cleanability of the paint, only the method itself is specified, not the fouling agent.

Note that since these properties depend not only on the quality of the coating, but also on the substrate, application method, drying conditions and other factors, the obtained results cannot be directly transferred to actual practice. 在本标准中, coatings are evaluated based on defined substrates, fixed application methods, specified drying conditions and defined wet scrubbing methods.
