Disclosure to Promote the Right To Information

Whereas the Parliament of India has set out to provide a practical regime of right to
information for citizens to secure access to information under the control of public authorities,
in order to promote transparency and accountability in the working of every public authority,
and whereas the attached publication of the Bureau of Indian Standards is of particular interest
to the public, particularly disadvantaged communities and those engaged in the pursuit of
education and knowledge, the attached public safety standard is made available to promote the
timely dissemination of this information in an accurate manner to the public.

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 originally published in 1966 and revised in 1977.
In the first revision, the following changes were made:
a)

The
1)
2)
3)

b)

The following constructions were deleted because of their limited use:

1) 6x12 (12-tibre)
2) 6x24 (15/9-fibre)
The requirements common to various types of wire ropes were deleted and a reference was made to
IS 6594:1977 Technical supply conditions for wire ropes and strands (first revision).
Breaking load of wire ropes manufactured ffom steel wires of tensile designation 1960 was added.
Provision of supplying the wire ropes with wires strand core (WSC) was made.

c)
d)
e)

following constructions were added in view of their increased use:

6x37 (18/12/6-1)
17x7 (6-1)
18x7 (6-1)

In this revision, the following important changes have been made:

a)
b)
c)
d)

Designation of various construction of wire ropes have modified in line with IS 6594:2001 Technical
supply conditions for steel wire ropes and strands (second revision).
6 x 26 SW, 6 x 31SW and 6 x 36SW constructions have been included under one group in this standard,
considering the market demand.
Provision for use of sofi fibre (jute) core is also included.
Mass and breaking force given in various tables have been modified as per the revised mass factor (K)
and breaking force factor (K) given in IS 6594.

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.

4 ROPE SIZE AND TOLERANCE

This standard covers the requirements for small wire

ropes for general purposes. The following rope
constructions, types, rope grades, cores and range of
sizes are included in this standard as identified by x
marrc

The size of the rope designated as nominal diameter

shall be one of those given in Tables 1 to 5. The actual
diameter of the rope shall be within the specified
tolerances shown in respective tables.

coating and length of wire rope, reel/coil number along
with the order number of purchaser and any other
marking which may be specified by the purchaser shall
be legibly mentioned on a suitable tag securely
attached, when wire ropes are supplied in coils. In case
wire ropes are supplied in reels, the information may
