7、文版)。本标准等同翻译IEC61520:20000为了便于使用，本标准做了下列编辑性修改:a)“本国际标准”一词改为“本标准”;h)用小数点“.”代替作为小数点的逗号“，”;c)删除了IEC61520;2000的前言和引言本标准更正了IEC61520:2000的编辑性错误:a)IEC61520:2000中2.2的术语“insertionlengthU'，与2.3的术语“insertionlengthU,”同名，而且在标准其余条款中均为“immersionlengthU"，因此将其更正为“immersionlengthU"b)IEC6152

8、0:200。中2.3的术语名称后面有一括号说明:“(仅D型套管的U与U不同)”，但从标准的附图中可以看出，A型和B型套管的U,也与U不同，仅C型套管的U.与U相同。这个说明并无存在必要，为此将
