ISO 12944-6:2018规定了评估碳钢结构防腐涂料体系的实验室试验方法和试验条件。 试验结果旨在帮助选择合适的油漆系统，而不是作为确定耐久性的准确信息。 ISO 12944-6:2018涵盖了根据ISO 1461设计用于未涂层钢、热浸镀锌钢和根据ISO 2063-1和ISO 2063-2热喷涂金属涂层的钢表面的保护涂料系统。 ISO 12944-6:2018不适用于电镀或涂漆钢的防护涂料系统。 考虑ISO 12944-2中定义的腐蚀性类别C2至C5和Im1至Im3的环境。

ISO 12944-6:2018 specifies laboratory test methods and test conditions for the assessment of paint systems for the corrosion protection of carbon steel structures. The test results are intended to be considered as an aid in the selection of suitable paint systems and not as exact information for determining durability. ISO 12944-6:2018 covers protective paint systems designed for application to uncoated steel, hot dip galvanized steel according to ISO 1461 and steel surfaces with thermal-sprayed metallic coating according to ISO 2063？1 and ISO 2063？2. ISO 12944-6:2018 does not apply to protective paint systems for electroplated or painted steel. The environments for corrosivity categories C2 to C5 and Im1 to Im3 defined in ISO 12944？2 are considered.
