NATIONAL FOREWORD
This Indian Standard (Part 1/Sec 1) (Second Revision) which is identical to IEC 60793-1-1 : 2022 'Optical fibres - Part 1-1: Measurement methods and test procedures - General and guidance' issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of Fibre Optics, Fibres, Cables And Devices Sectional Committee and approval of the Electronics and Information Technology Division Council.
This standard was first published in 2012 and was identical to IEC 60793-1-1 : 2008. It was subsequently revised in 2018 and was identical to IEC 60793-1-1 : 2017. The second revision of this standard has been undertaken to align it with the latest version IEC 60793-1-1 : 2022. On publication of this Indian Standard, the previous versions shall be withdrawn.
This standard is one of the parts of a series of standards on 'optical fibres'. The other parts/sections of this series are published as IS/IEC 60793 standards.
The text of IEC standard has been approved as suitable for publication as an Indian Standard without deviations. 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 Standards, the current practice is to use a point (.) as the decimal marker.
