Editorial national differences (those marked DE) are not included inthis technical compilation.In its IEC-based standards, UL uses the notations indicated below to identify national difference type, andthese types are additionall
20、y noted in this document. The standard may not use all types of thesedeviations.DR - These are deviations based on the National Electrical Code (NEC) and other U.S. RegulatoryRequirements.D1 - These are deviations which are based on basic safety principles and requirements, elimination ofwhich would
21、 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 are
22、 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 correctionsJANUARY 16, 2004NATIONAL DIFFERENCES FOR UL UL 60730-2-184UL COPYRIGHTED MATERIA
