本欧洲标准规定了对双组分聚氨酯面漆的要求，其具有中等程度的抵抗侵蚀的作用，可以在一系列颜色和光泽度范围内使用，具有一定范围的颜色和光泽度，适用于在地面上进行航空航天应用的底漆亚音速下的雨侵蚀可能是一个问题，例如前缘和进气口。 本欧洲标准规定的性能是根据EN 3837程序A和EN 23270制备的定义的铝合金试件获得的，并涂上EN 2435-001和-002的底漆。应通过补充测试来确定材料用于特定应用（例如替代底物，替代底漆，特定干燥条件等）的能力，以确认满足本欧洲标准的要求

This European Standard specifies the requirements for a two component polyurethane, topcoat, with a medium degree of resistance to erosion by the effects of rain, available in a range of colours and levels of gloss, to be applied over a primer for aerospace applications on areas where rain erosion at subsonic speeds may be a problem, e.g. leading edges and air intakes. The properties specified in this European Standard are obtained on defined aluminium alloy test pieces prepared in accordance with EN 3837 Procedure A and EN 23270 and painted with primer to EN 2435-001 and -002. The ability of the material to be used for a specific application (e.g. alternative substrate, alternative primer, specific drying conditions, etc.) should be determined by supplementary tests to confirm that the requirements of this European Standard are met.
