This standard was first published in 1963,revised in 1970, 1977 and 1989. The first revision was taken up to align the standard with the corresponding 1S0 standard, 1S02408: 1975‘Steelwire ropes forgeneral purposes — Characteristics’. [n the second revision, published in 1977, certain changes inthe listof constructions were made. In the third revision, the construction 6 x 19(12/6/1) with steelcore (CWR) was added and the requirement of galvanizing was modified. The experience gained inimplementation ofthe standard necessitated this revision andcertain changes that are necessary are incorporated inthis revision. The composition of the Committee responsible for the formulation ofthis standard is given in Annex A. For the purpose of deciding whether aparticular requirement ofthis standard iscomplied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with 1S2:1960 ‘Rules for rounding off numerical values (revisec$’. The number of significant places retained in the rounded off value should be the same asthat ofthe specified value inthis standard. .
