9、OT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULPrefaceThis document provides a single listing of the technical National Differences included in the UL adoptionof the corresponding IEC standard.In its IEC-based standards, UL uses the notations indicated below to ident
10、ify national difference type, andthese types are additionally noted in this document. The standard may not use all types of thesedeviations.D1 - These are deviations which are based on basic safety principles and requirements, elimination ofwhich would compromise safety for U.S. consumers and users
11、of products.D2 - These are deviations based on safety practices. These are deviations for IEC requirements that maybe acceptable, but adopting the IEC requirements would require considerable retesting or redesign on themanufacturers part.DC - These are deviations based on the component standards and
12、 will not be deleted until a particularcomponent standard is harmonized with the IEC component standard.DE - These are deviations based on editorial comments or corrections.DR - These are deviations based on the national regulatory requirements.Each national difference contains a description of what
13、 the national difference entails. Typically one of thefollowing words is used to explain how the text of the national difference is to be applied to the base IECtext:Addition / Add - An addition entails adding a complete new numbered clause, subclause, table,figure, or annex. Addition is not meant t
14、o include adding select words to the base IEC text.Deletion / Delete - A deletion entails complete deletion of an entire numbered clause, subclause,table, figure, or annex without any replacement text.Modification / Modify - A modification is an altering of the existing base IEC text such as theaddi
15、tion, replacement or deletion of certain words or the replacement of an entire clause,subclause, table, figure, or annex of the base IEC text.MARCH 6, 2015 NATIONAL DIFFERENCES FOR UL UL 61800-5-1 3UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM
