2004版中的描述: The height of graphical symbols shall not be
less than 5 mm except that the symbols for class II and class III luminaires and for the F mark
may be reduced to a minimum of 3 mm where the space available for marking is restricted.
我的理解:除了二类,三类标示, 和F标示的高度因产品上空间的限制可以小到3MM之外, 灯俱上的其它符号的高度不能小于5MM.
2008版中的描述: 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.
这句话好像是说: :二类,三类符号高度不能小于5MM, 灯俱上的其它符号的高度因产品上空间的限制可以小到3MM.
不知道各位是怎么理解2008版的? |
