Editorial national differences (those

33、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 additionally noted in this document. The standard may not use all types of thesedeviations.DR - These are deviations bas

34、ed 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 compromise safety for U.S. consumers and users of products.D2 - These are deviations based on safety practic

35、es. 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 will not be deleted until a particularcomponent standard is

36、harmonized with the IEC component standard.DE - These are deviations based on editorial comments or correctionsOCTOBER 30, 2002 NATIONAL DIFFERENCES FOR UL UL 60730-2-6 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULNational Differences2.2.1
