好象还真没碰到查到这个的，只要有个标志在上面就行了吧。至于线径，应该不小到正常肉眼看不清为限吧。其它，应该以整体协调美观为主吧。

随便画一个“回”， 然后按标准，此符号整体高度5mm，空间有限时可以缩小到3mm的规定就可以了。

急需标准依据!!!

对，要有标准依据才能说明问题

The height of graphical symbols shall not be less than 5 mm, except for symbols for class II and class III luminaires, and may be reduced to a minimum of 3 mm where the space available for marking is restricted. The height of letters and numerals either shown separately or with or as part of symbols shall not be less than 2 mm.

See EN61029-1 (you can find the similiar requrements in EN60745/EN60335/EN60598/EN60590, etc.)

The dinemsions of the symbol of class II shall be such that the length of the sides of the outer square is about twice the length of the sides of the inner square.

The lenght of the sides of the outer square shall not be less than 5mm

The symbol for class II tools shall be so plased that it will be obvious that it is a part of the technical information and is unlikely to be confused with any other marking.

其实这个标志就是IEC60417的symbol 5172
