研磨区域应扩展到要涂敷的区域之外至少25毫米(1英寸)。
If the DFT is reduced to less than specified, the area shall be abraded as described above and an additional layer of coating shall be applied until sufficient thickness is achieved.如果干膜厚度缩减到低于指定时,该区域按照之前描述的进行研磨,并应再涂敷额外的一层保护层直到达到足够厚度。
The abraded surface shall extend at least 25mm (1 inch) beyond the coated area.磨面应至少扩展到涂敷区域外25毫米(1英才)。
