NATIONAL FOREWORD

This Indian Standard (Part 1) which is identical with IEC 62255-1 : 2003 ‘Multicore and symmetrical pair/quadcables for broadband digital communications (high bit rate digital access telecommunication networks) —Outside plant cables — Part 1: Generic specification’ issued by the International Electrotechnical Commission(IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Wires, Cables, Waveguidesand Accessories Sectional Committee and approval of the Electronics and Information Technology DivisionCouncil.

The text of IEC Standard has been approved as suitable for publication as an Indian Standard withoutdeviations. Certain conventions are, however, not identical to those used in the Indian Standards. Attentionis particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as‘Indian Standard’.

b) Comma (,) has been used as a decimal marker in the International Standard while in Indian Standards,the current practice is to use a point (.) as the decimal marker.

In this adopted standard, reference appears to certain International Standards for which Indian Standardsalso exist. The corresponding Indian Standards which are to be substituted in their respective places arelisted below along with their degree of equivalence for the editions indicated. For undated references, thelatest edition of the referenced document applies.
