This standard (Part 1) was first published in 1996. The first revision has been undertaken to bring it in line with latest version of corresponding IEC publication. The text of the IEC Standard has been approved as suitable for publication as an Indian Standard without deviations. In this adopted standard, certain terminology and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following: a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’; and b) Comma (,) has been used as a decimal marker while in Indian Standard, the current practice is to use a point (.) as the decimal marker. Only the English text of the IEC Publication bas been retained while adopting it as an Indian Standard, and as such the page numbers given here are not same as in IEC Publication. In the case of drawings and tables only the English text may be referred. CROSS REFERENCES In this adopted Indian Standard, reference appears to certain International Standards for which Indian Standards also exist.
