ISO 12944-8:2017涵盖了使用防护涂料系统的钢结构防腐规范的制定。它涉及车间或现场的新工作和维护，也适用于单个部件的防腐。ISO 12944-8:2017涵盖了暴露于不同腐蚀应力环境下的钢结构的腐蚀防护，例如室内、露天、浸入水中或埋在土壤中，以及由于中高温等特殊应力。考虑了不同耐久性范围的需要。 已经热浸镀锌、金属喷涂、镀锌或镀锌的钢表面，以及之前涂漆的钢表面，也包含在ISO 12944-8:2017中。 在ISO 12944-8:2017中，涉及了用于评估防腐工程质量和所用防护涂料系统性能的参考区域。 ISO 12944-8:2017提供了规划新工作和维护的详细流程图，在编写规范时将其考虑在内。 如果出现极端腐蚀应力或高温，或者如果要在其他基材（如有色金属或混凝土）上使用防护涂料系统，则ISO 12944-8:2017也可以用作指南，以定义合适的规范。

ISO 12944-8:2017 covers the development of specifications for corrosion protection of steel structures using protective paint systems. It relates to new work and maintenance in the workshop or on site and is also applicable to the corrosion protection of individual components. ISO 12944-8:2017 covers the corrosion protection of steel structures exposed to different corrosion stresses by environments such as indoors, open-air and immersion in water or burial in soil, as well as special stresses, due for example, to medium or high temperatures. The need for different durability ranges is considered. Steel surfaces that have been hot-dip-galvanized, metal-sprayed, zinc-electroplated or sherardized, and previously painted steel surfaces, are also covered by ISO 12944-8:2017. In ISO 12944-8:2017, reference areas for assessing the quality of the corrosion protection work and the performance of the protective paint systems used are dealt with. ISO 12944-8:2017 provides detailed flow charts for planning new work and maintenance, which are taken into account when writing a specification. ISO 12944-8:2017 can also be used as a guide if extreme corrosion stresses or high temperatures occur, or if the protective paint systems are to be used on other substrates, such as non-ferrous metals or concrete, to define suitable specifications.
