5、n indicated.The standard should be applied when there is obvious 此標準適應于有如下明顯危害的情況：risk of personal injury 造成人身傷害的情況 functional disturbance 功能失調的情況 corrosion 有腐蝕的情況For parts which are to be painted it may sometimes be 對于要噴漆處理的工件來說，有時有必要說明necessary to specify that the edges shall be broken. 工件的邊緣應該倒鈍。

6、The reason for this is that the paint film is less thick on 原因是，在尖銳的邊（邊的角度< 90°) 上的噴漆a sharp edge (angle of edge < 90°) and, should the 膜更加的薄。如果零件又處于一個腐蝕性的環境part be used in a corrosive environment, corrosion 中，很可能又會出現零件的腐蝕。might arise.The requirements concerning edge free from burrs
