9、s, UL uses the notations indicated below to identify 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 woul
10、d compromise safety for U.S. consumers and users 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 ar
11、e deviations based on the component standards and 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 n
12、ational difference contains a description of what 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
13、, table,figure, or annex. Addition is not meant to 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 alter
14、ing of the existing base IEC text such as theaddition, replacement or deletion of certain words or the replacement of an entire clause,subclause, table, figure, or annex of the base IEC text.SEPTEMBER 20, 2011 NATIONAL DIFFERENCES FOR UL UL 61496-1 3UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER
