FOREWORD
This Indian Standard (Second Revision) was adopted by the Bureau of Indian Standards, after the draft finalized
by the Wire Ropes and Wire Products Sectional Committee had been approved by the Mechanical Engineering
Division Council.
This standard was first published in 1963 and subsequently revised in 1977. While revising this standard, 6 X 25
(22/12/A) triangular strand construction of wire rope has been deleted from the standard because of the limited
use. Also the title of the standard has been slightly modified.
In this revision, the rope size and tolerance shall be within +6/-0 percent of the nominal diameter for nominal
rope diameter up to 10 mm (≤ 10 mm) and +5/-0 percent for nominal rope diameter larger than 10 mm
(>10 mm), and minimum breaking force for rope diameters not covered in these tables can be calculated as per
IS 6594 : 2018 Technical supply conditions for steel wire ropes and strands (third revision). Values of rope
grade for dual tensile grade ropes to calculate minimum breaking force are given in Annex A.
The composition of the Committee responsible for the formulation of this standard is given in Annex B.
For the purpose of deciding whether a particular requirement of this standard is complied with the final value,
observed or calculated, expressing the result of a test or analysis shall be rounded off in accordance with
IS 2 : 1960 ‘Rules for rounding off numerical values ( revised ). The number of significant places retained in the
rounded off value should be the same as that of the specified value in this standard.

1 SCOPE
This standard covers steel wire ropes for use with lifts, elevators and hoists having cars or platforms carrying
passengers or goods and working in guides. This standard does not apply to ropes used for winding purpose in
mines. The following rope constructions, types, rope grades, cores and range of sizes are covered as identified by
“X” mark:
