The standard may not use all types
10、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 of products.D2 - These are deviations based on safety practices. These are deviations for IEC requirements that maybe acc
11、eptable, 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 harmonized with the IEC component standard.DE - These are de
12、viations based on editorial comments or corrections.DR - These are deviations based on the national regulatory requirements.Each national 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 dif
13、ference 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 to include adding select words to the base IEC text.Deletion / Delete - A deletion entails complete deletion of an entire
14、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 theaddition, replacement or deletion of certain words or the replacement of an entire clause,subclause, table, figure, or annex
