FOREWORD

This Indian Standard (Third Revision ) was adopted by the Bureau of Indian Standards on
23 October 1989, after the draft finalized by the Wire Ropes and Wire Products Sectional Committee
had been approved by the Heavy Mechanical Engineering Division Council.
This standard was first published in 1963. In order to align the standard with the corresponding IS0
Standard IS0 2408 : 1973 ‘Steel wire ropes for general purposes - Characteristics’, the standard was
iirst revised in 1970.
In the second revision published in 1977, certain changes in the list of constructions were made. In
view of the experience gained in the industry, the Committee decided to revise the standard.
Accordingly, in this third revision, the construction 6 x 19 ( 12/6/l ) with steel core ( IWRC ) has
been added and Tables 2 and 3 and requirements for galvanizing have been modified.
