EN 60950-1 includes the basic requirements for the safety of information technology equipment. Additional parts of EN 60950-1 will cover specific safety
21、 requirements for information technology equipment having limited applications or having special features as follows: Part 21: Remote power feeding; Part 22: Equipment installed outdoors; Part 23: Large data storage equipment. Except for notes, all text within a normative figure, or in a box under a
22、 normative table, is also normative. Text with a superscript reference is linked to a particular item in the table. Other text in a box under a table applies to the whole table. Informative annexes and text beginning with the word “NOTE“ are not normative. They are provided only to give additional i
23、nformation. In this standard, the following print types are used: Requirements proper and normative annexes: roman type. Compliance statements and test specifications: italic type. Notes in the text and in tables: smaller roman type. Terms that are defined in 1.2: SMALL CAPITALS. The following dates
24、 were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2006-12-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2010-12-01 Clauses, subclauses, notes, t
