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: of copper and masses of copper refinery shapes of copper refinery shapes for chemiPart I Part II Part III Part IV Part V Part VI Part VII Part VIII Part IX Part X Classification Dimensions Methods of sampling cal analysis Cathode Electrolytic copper tough pitch copper ( ETP ) copper ( FRHC wrought ) products and Fire refined high conductivity Fire refined tough pitch copper alloys ( FRTP-1 and PRTP-2 ) Phosphorized Arsenical Phosphorus copper ( DHP) ( ATP) arsenical tough pitch copper deoxidized copper ( DPA ). 3 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, 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. *Rules for roundingoff numerical values (, wched ). 4 lbrl9i (Pa&)-1980 Indian Standard SPECIFICATION FOR COPPER PART I CLASSIFICATION OF’ COPPER ( 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, provided 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 pieces as gross samples from each of the to 2 unless otherwise agreed to between 3.1.1 For sampling, take three lots ( charges, shapes ) dccording 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 of iron. III ) - I999 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 adjacent 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 this clause, take the measures indicated in 3.2. 3.2 Procedure for Investigation of Claims according tc 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 adjacent 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. 16 Is t 191( Part IV ) - 1980 Indian Standard SPECIFICATION PART IV FOR COPPER COPPER CATHODE ( Third Revision ) 1.
