DC - national differences based on UL and CSA component requirements. DC
national differences may be less stringent than, equivalent to, or more stringent than
component requirements in IEC 60950-1.

DE - editorial national differences that correct typographical errors in IEC 60950-1 or
revise the terminology, but do not alter the technical intent of the requirements. This
notation is also used for informative statements such as the Preface.

其實還有很多,這些定義在UL標準非常前面的General的地方有定義.
