FOREWORD This Indian Standard (Third 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 1963, revised in 1970 and in 1977. The first revision of the standard was necessitated so as to incorporate the changes felt necessary in implementation of the standard. In the second revision of the standard, the following important changes were made:
a) Scope of the standard was expanded to include the haulage wire ropes used other than in the mines. Hence the title of the standard was accordingly modified.
b) The following constructions of wire ropes were added as it had been found that these constructions were being used in increased quantities:
1) 6 × 17 S (881) 2) 6 × V9 (8∆) 3) 6 × 23 (10/12∆)
c) The requirements common to various types of wire ropes were deleted and a reference has been made to IS 6594 : 2001 'Technical supply condition for steel wire rope and strands (second revision)'.
d) Minimum breaking loads for wire ropes to rope grade of 1960 were added.
In this third revision, the following changes have been made:
a) Designation of various construction of wire ropes have been modified in line with IS 6594. b) Provision for use of soft fibre (jute) core is included. c) Requirement of joints has been modified. d) 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.
The composition of the Committee responsible for formulation of this standard is given in Annex A. 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.

8.1 Lot
Steel wire rope of same size manufactured using the same set of strands and same type of core under identical condition of production, shall constitute a lot
NOTE — Manufacturer shall provide evidence for the tractability of the individual rope lengths to the parent rope to estalish that those represent the lot as defined above.
8.2 For ascertaining the conformity of a lot, the following sampling plan shall be made:
a) Dimensional checking — 100 percent b) Breaking force test — one sample from a lot

3 TERMINOLOGY For the purpose of this standard, the definitions given in IS 2363 shall apply.
5 MINIMUM BREAKING FORCE Minimum breaking force of ropes shall be as given in Tables 1 to 4.
6 GENERAL REQUIREMENTS 6.0 The wire rope shall conform to IS 6594 and shall also meet the following requirements.
6.1 Core 6.1.1 Fibre Core Use of soft fibre (Jute) core according to IS 1804 is permitted. 6.1.2 Steel Core
Steel core shall be according to IS 6594.
6.2 Joints 6.2.1 The joints in wires shall be avoided as far as possible, except where they are necessitated by the length of the rope; those in the wires of the strand shall be distributed as widely apart as possible, and in no case shall more than one wire be jointed in any length of 10 m of strand.

IS 1856 : 2005
6.2.2 The joints shall be either brazed or electrically welded. If joints are brazed they shall be properly scarfed, if welded, properly annealed. Tucked joints in wires during rope making may be used for wires of 0.5 mm diameter and smaller.
6.3 Lay The lay of the rope shall be either ordinary lay or Lang's lay.
6.4 Mass
The approximate rope masses given in Tables 1 to 4 are for fully greased ropes. The ropes that are not lubricated may be lighter.
6.5 Preforming All ropes shall be preformed unless otherwise agreed to between the purchaser and the manufacturer.
7 GALVANIZING When required, galvanizing shall conform to Type B of IS 1835 unless specified otherwise by the purchaser.
8 MARKING 8.1 The size, construction, rope grade, lay, core, 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 be stenciled on both sides of the reels or stenciled on one side of the reel and a suitable tag giving the same information may be attached on the other side of the reel.
8.2 BIS Certification Marking The product may also be marked with the Standard Mark.
8.2.1 The use of the Standard Mark is governed by the provisions of the Bureau of Indian Standards Act, 1986 and the Rules and Regulations made thereunder. The details of conditions under which a license for the use of Standard Mark may be granted to manufacturers or producers may be obtained from the Bureau of Indian Standards.
