10、d based on IEC 60554-3-1 Specification for cellulosic papers for electrical purposes-Part 3 : Speci- fications for individual materials-Sheet 1 : General purpose electrical paper published in 1979 as the first edition in such a manner that the insulating paper for electric power cables specified in
11、the former Japanese Industrial Standard are specified in the text and the specifications in the corresponding International Standard (types 1.1 to 1.4) which cover the area of above JIS are adopted as the Annex. 1 Scope This Japanese Industrial Standard specifies electrical insulating papers, especi
12、ally for electrical cables (hereafter referred to as “papers”). In this Standard, specifications in either of the text or the Annex are applicable for a product consistently and it is not allowed to select or mix at ones own discre- tion the corresponding specification items and the contents stated
13、in the said both parts. Remarks : The International Standard corresponding to this Standard is given below.
