标准范围

ISO 12944-4:2017涵盖了由碳钢或低合金钢组成的钢结构表面的以下类型及其制备:-无涂层表面；-热喷涂锌、铝或其合金的表面；-热浸镀锌表面；-镀锌表面；-硬化表面；-涂有预制底漆的表面；-其他涂漆表面。ISO 12944-4:2017定义了许多表面处理等级，但未规定表面处理前基底条件的任何要求。ISO 12944-4:2017未涵盖高度抛光表面和加工硬化表面。

ISO 12944-4:2017 covers the following types of surfaces of steel structures consisting of carbon or low-alloy steel, and their preparation:- uncoated surfaces;- surfaces thermally sprayed with zinc, aluminium or their alloys;- hot-dip-galvanized surfaces;- zinc-electroplated surfaces;- sherardized surfaces;- surfaces painted with prefabrication primer;- other painted surfaces.ISO 12944-4:2017 defines a number of surface preparation grades but does not specify any requirements for the condition of the substrate prior to surface preparation.Highly polished surfaces and work-hardened surfaces are not covered by ISO 12944-4:2017.
