25、.03-1996 NOTEThe editing instructions contained in this corrigendum define how to merge the material contained therein into the existing base standard and its amendments to form the comprehensive standard. The editing instructions are shown in bold italic. Four editing instructions are used: change,

26、 delete, insert, and replace. Change is used to make corrections in existing text or tables. The editing instruction specifies the location of the change and describes what is being changed by using strikethrough (to remove old material) and underscore (to add new material). Delete removes existing

27、material. Insert adds new material without disturbing the existing material. Insertions may require renumbering. If so, renumbering instructions are given in the editing instruction. Replace is used to make changes in figures or equations by removing the existing figure or equation and replacing it

28、with a new one. Editorial notes will not be carried over into future editions because the changes will be incorporated into the base standard. 5.5.35.3.3Rating Rated dielectric strength Rated chopped-wave lightning-impulse voltage Change the text in 5.3.3 as shown: The rated chopped-wave lightning-i
