This standard was first issued in 1984. The experience gained in the implementation of the standard since its issue has necessitated the present revision. The following are the major changes in this revision: a) Symbolic representation of various constructions of wire ropes has been modified. b) Size ranges modified as: 13to 44 mm diameter in place of 13to 40 mm diameter for 6 x 17 Sand 6 x 19 Sconstruction. c) Cross lay construction 6 x 19M (12/6-1) has been deleted since the same is not recommended to haulage system. d) Requirement for lubrication has been added. e) Requirement of mass and breaking force have been modified as per the mass factor ‘K’ and breaking force factor ‘K’ given in IS 6594:2001 ‘Technical supply conditions for steel wire ropes (second revision)’. The composition of the Committee responsible for the formulation of this standard is given in Annex A. For the purpose of deciding whether aparticular 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 inthe rounded off value should be the same as that of the specified value inthis standard.
