急需标准依据!!!
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
