0.2 This standard was first published in 1970 to cover the requlrementsof strands used in prestressed concrete work. The present revision hubeen taken up with a view to incorporating modifications found necessaryas a result of use of this standard both by manufacturers and users.
0.3 The significant modifications incorporated in this revision are inrespect of provisions relating to physical requirements of nominal manof strand and proof load and the sample size for tensile test. Further,SI units have been adopted in the revision and references to relatedIndian Standards appearing in the standard have been updated.
0.4 In the formulation of this standard, due weight age has been givento international co-ordination among the standards and practicesprevailing in different countries in addition to relating it to the practicesIn the field in this country,
0.5 For the purpose of deciding whether a particular requirement ofthis standard is complied with, the final value, observed or calculated,expressing the result of a test shall be rounded off in accordance withIS: 2·1960*. The number of significant places retained in the rounded offvalue should be the lame as that of the specified value in this standard.
1.ICOPE1.1 This standard covers the requirements for manufacture, supply andtesting of uncoated, stresl relieved, high tensile steel strands for use inprestreased concrete, The following types of strand. are covered:

The initialload shall be applied in a period of 5 minutes and shall then be heldconstant for a further period of one minute. Thereafter no adjustmentof load shall be made, and load relaxation readings shall commencefrom the end of the sixth minute. On no account shall the test specimenbe overstressed.
