( Third Revision

0. FOREWORD

0.1 This Indian Standard ( Third Revision) was adopted by the Indian Standards Jnstitution on 23 April 1980, after the draft finalized by the Copper and Copper Alloys Sectional Committee had been approved by the Structural and Metals Division Council.

0.2 The second revision of this standard was published in 1967. The committee responsible for the preparation of this standard felt that different types of coppers included in the earlier version of the standard should be reviewed and classified. While revising IS : 191, it was decided to exclude grades OF and DHPz because of their limited use, and cover the requirements of other types of copper in series of parts to be published as third revision of IS : 191. Method of sampling of copper refinery shapes for chemical analysis has also been incorporated in this revised standard, as Part III. The method is based on ISO/R 1811-1971 ‘Chemical analysis of copper and copper alloys - Sampling of copper refinery shapes’, published by the International Organization for Standardization.

0.2.1 This standard is being issued in 10 parts as follows:

Part I

ISr191(PortsItoX)-1980

0.3 In the preparation of this standard, consideration has been given to the manufacturing and trade practices followed in the country in this field. Assistance has been derived from ISO/R 197-1961 ‘Classification of copper ’ published by the International Organization for Standardization.

0.4 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, express- ing 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.

PART I CLASSIFICATION OF’ COPPER

( Third Revision ) 1. SCOPB

1.1 This standard ( Part I ) defines various types of coppers and currently available cast refinery shapes. It includes a table which classifies these grades of copper indicating the shapes in which these coppers are available.

2 TERlwIuOLoGY

2.0 For the purpose of this standard, the following definitions shall apply.

&l cop*

2.1.1 Copper- For the purpose of this classification, copper containing not more than 8.5 percent of alloying elements is included in the term Qopper’.

2.1.2 Tough Pitch CoppGr - Copper, either electrolytically or fire refined, cast in the form of refinery shapes, containing a controlled amount of oxygen for the purpose of obtaining a level set in the casting. By extension, the term is applicable to fabricators’ products made therefrom.

2.1.3 Etectrolytic Co~~sr ( ETP ) -Copper, of any origin, refined by electrolytic deposition. Usually when this term is used alone, it refers to electrolytic tough pitch copper. This designation applies to the following.

2.1.3.1 Cathodes, that are the direct products of refining operation.

2.1.3.2 Electrodeposited copper, cast from melted cathodes into refinery shape, suitable for hot or cold working or both, and by extension, fabticators’ products made therefrom.

2.1.3.3 Electrodeposited copper, cast into ingot or ingot bar, suitable for remelting.

2.1.4 Fire-ReJinsd High ConductiviQ Copper ( FRHC) - Copper which, in the annealed condition, has a minimum electrical conductivity of 100 percent of International Annealed Copper Standard.

5

L-_ ~.~._~~-~_~..-^_~~~. ..^

IS:191 (PartI)-

2.1.5 Fire-Refined Copper -Copper of any origin or type finished by furnace refining. Usually when the term ‘fire refined copper’is used alone, it refers to fire-refined tough pitch copper. This desginatlon applies to the following:

a) Copper cast in the form of refinery shapes suitable for hot or cold working or both, and by extension, fabricators’ products made therefrom ( FRTP-1 ).

b) Ingot or ingot bar suitable for remelting ( FRTP-2 ),

2.1.5.1 Casting co@er - Fire-refined tough pitch copper, usually cast from melted secondary metal into ingot and ingot bars only and used for making foundry castings.

2.1.6 Deoxidized Copper-Copper cast in the form of refinery shapes, produced free from cuprous oxide through the use of deoxidizers. By extension, the term applies to fabricators’ products made therefrom.

2.1.7 Deoxidized Copper High Residual Phosphorus ( DHP ) - Copper deoxidized by phosphorus usually residual in excess. It is not susceptible to hydrogen embrittlement but is of a relatively low electrical conductivity due to the amount of phosphorus present.

2.1.8 Arsenical Tough Pitch Copper ( ATP) - Copper containing arsenic in amounts as agreed to between the supplier and the purchaser and are produced as tough pitch variety.

2.1.9 Phosphorus Deoxidized Arsenical Copper ( DPA ) - Copper deoxidized by phosphorus and containing arsenic in amounts as agreed to between the supplier and the purchaser.

2.2 Refinery Shapes

2.2.1 Wire Bar - Refinery shapes for rolling into rod ( and subsequent drawing into wire ), strip or shape.

Approximately 85 to 125 mm square in cross-section, usually from 1 000 to 1 375 mm in length and weighing from 60 to 190 kg. Tapered from end to end, when used for rolling into rod for subsequent wire drawing, and may be unpointed, when used for rolling into strip. Cast either horizontally or vertically.

2.2.2 Billet - Refmery shape primarily for tube manufacture. Circular in cross section, usually 75 to 250 mm in diameter and lengths up to 1 300 mm, and mass from 45 to 680 kg.

PART III METHODS OF SAMPLING OF COPPER REFINERY SHAPES FOR CHEMICAL ANALYSIS

( Third Revision ) 1. SCOPE

1.1 This standard ( Part III ) covers methods for preparation of sample of copper refinery shapes for chemical analysis. The shapes covered are wire bars, billets, cakes, slabs, ingots and ingot bars, and cathodes.

2. CONSIGNMENTS OF LOTS

2.1 For the determination of the copper content, consignments up to a total mass of about 300 tonnes should be considered as a single lot, provi- ded that the whole of the consignment is of the same charge and consists of uniform shapes. Consignments exceeding 300 tonnes in total mass should be divided into lots of approximately equal size.

2.2 If a consignment conFists of several charges and/or different shapes, the consignment should be divided into lots according to charges and shapes. The size ofthe lots depends on the charges and shapes forming the consignmint concerned and/or on the arrangements made between the interested parties.

3. PROCEDURE

3.1 Conventional Procedure

3.1.1 For sampling, take three pieces as gross samples from each of the lots ( charges, shapes ) dccording to 2 unless otherwise agreed to between the interested parties;

3.1.2 Remove surface contamination, if any, from the three pieces, and also remove any surface oxide layer from those areas where samples are to be taken. Drill holes completely through each piece, or, if the pieces are too thick, drill holes from two opposite sides to the centre. Do not use lubricants or similar substances. The Fill should be of cemented carbide or other suitable hard metal*, and should not contain substantial quantities

l For example, bonded tungsten carbide drill or carbide tipped drill.

IS : 191 (Part III ) - I999

of iron. The drill shotild be 10 to 15 mm in diameter and be designed to produce drillings as small and short as possible. The drillings shquld have a metallic lustre and should be free of oxidation. DO not force the drill to such an extent as to cause oxidation of the chips. If oxidized chips are obtained, reject all the chips from that hole and drill another hole adja- cent to the original to provide an unoxidized sample.

3.1.3 Use a uniform hole pattern over the three pieces of the gross sample taken from each lot. In principle, distribute the holes in such a way that at least one hole is drilled within each 25 cm* of the surface area. Mix thoroughly the drillings obtained in this way.

3.1.4 If less than 2 kg ( approximate value ) of drillings are obtained per lot, increase the number of holes by whole multiples of the original number of holes. If, on the other hand, more than 2 kg ( approximate value ) of drillings are obtained per lot, reduce them to about 2 kg by quartering.

3.1.5 Divide the 2 kg sample into four parts for analysis of about 500 g each, place each in a bottle, label, and seal. Send one sample to each of the interested parties and retain one as a referee sample and another as a reserve sample, or distribute them according to the arrangements made between the interested parties.

3.1.6 In case no agreement is reached when proceeding according tc this clause, take the measures indicated in 3.2.

3.2 Procedure for Investigation of Claims

3.2.1 Each party should select a sample of three pieces from the consignment or lot to be investigated. Carry out the sampling in the presence of both parties by drilling five holes approximately 12 mm in diameter, at points equally distributed between the ends of the pieces. With wire bars, billets, ingots and ingot bars, these holes should be along a middle line, and with slabs and cakes, on a diagonal line drawn between opposite corners. Drill completely through each piece from top to bottom. Remove skin and any surface dirt. Do not use lubricant and do not force the drill to such an extent as to cause oxidation of the chips. If oxidized chips are obtained, reject all the chips from that hole and drill another hole adja- cent to the original to provide an unoxidized sample. In the case of sections more than 125 mm in thickness, drill from both top and bottom for a depth of not less than 50 mm in each direction instead of drilling completely through each piece, but in all other respects conduct the drilling as previously described. Cut up the resulting sample, mix and separate into four equal portions, and plate each in a sealed package, one for the manufacturer, one for the purchaser, one for a referee, if necessary, and one as reserve.
