Indian Standard SPECIFICATION FOR

COPPER RODS AND BARS FOR ELECTRICAL PURPOSES

( Second Revision )

0. FOREWORD

0.11 This Indian Standard ( Second Revision ) was adopted 1)~ the Illtli;:il Standards Institution on 12 March 1984, after the draft filralized by t!lc: Copper and Copper Alloys Sectional Committee had been approved by tile Structural and Metals Division Council.

0.2 This standard was first lxlblished in 1954 and subsequently rc\-isctl in 1964. In view of the publication of revised version of IS : !91 ( Parts I LO 10 )-1980*, and IS : 3288 ( l’art 1 )-1981t it was felt necessary t:o rc\Gsc this standard to accommoclnte the material below 10 mm starts I‘ro!~1 6 mm.

0.3 In this revision the follo\ving modifications have been mxlc:

i) MKS units have been changed to SI units for all q!lz:‘lt itics a:.ti dimensions,

ii) Clauses for terminology, chemical composition, sampling allcl criteria for conformity have been modified, and

iii) Tensile properties for 6 to 10 mm size have been added.

,0.4 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calctrlated, esprc~- sing the result of a test or analysis, shall be rounded off in accorda~:c:c with IS : Z-1960$. The number of significant places rctainec! in ti;!: rounded off value should be the same as that of the specifieil valllc iI! ti:/; standard.

NOTE - The use of the ISI Certification Mark is governed by the provisiolis of the Indian Standards Institution ( Certification Marks ) Act and the Rules :~ntl Regulations made thercundcr. The ISI Mark on products covc:rctl by an Inrliarr Standard conveys the assurance that they have been produced to comply with the requirements of that standard under a well-defined system of insIxction, testing and quality control which is devised and supervised by ISI and operated by the proti~~- cer. IS1 marked products are also continuously checked by IS1 for conformity to that standard as a further safc~guard. Details of conditions under which a iiccnccb for the use of the ISI Certification Markpay be granted to manufact\lrers or proc~x~ors, may be obtained from the Indian Standards Institution.

12.2.1 The rods/bars selected in accordance with co1 1 and 2 of Table 4 shall be inspected for freedom from defects ( .W 6 ) and dimen- sions ( see 8). Any rod/bar failing to meet the requirement of one or more of these characteristics shall be considered as defective. If rh,. number of defectives found is less than or equal to the permissible I~uI:~Ix::. of defectives given in co1 3 of Table 4, the lot shall lx considcrc,l ;i:: conforming to the requirclnents of these characteristics.

NOTE 1 - Given the resistance of a wire at I’%, the resistance at 2D’C is fmlnd by multiplying the resistance at ‘PC by the constant for 7-Y: giv< x ill co1 2. Conversely, given the resistance at 2OYC, the corresponding resistance at ‘/ ,‘(: is i‘o::n4 by’multiplying the resistance at 20°C grven in co1 3.

NOTE 2 -The temperature coefficient of resistance of copper varies slight!y from, sample to sample according to its exact conductivity. The figures given m this table are based on a coefficient of 0.003 81/deg C at 20°C which is an avcragc value for copper of 97 percent conductivity. The error in using this table for copper &thin the range of conductivity of 96 to 98 percent will not exceed O’OG percent.
