0.2 This standard was publiihed in 1964 and subsequently revised in 1974 and 1980. In this revision, the tolerances on diameter 6 to 10 mm of rods and bars have been included.

0.3 F.or 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*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

1. SCOPE

1.1 This standard specifies dimensions and tolerances for copper and copper alloy rods and bars.

2. TERMINOLOGY

2.0 For the purpose of this standard, the definitions as given in IS : 3288 ( Part 3 )-1986t shall apply.
