3、tandards institutes (IS0 member bodies). The work of developing Inter- national Standards is carried out through IS0 technical committees. Every member body interested in a subject for which a technical committee has been set up has the right to be represented on that committee. International organi
4、zations, governmental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. International Standar
5、d IS0 431 was developed by Technical Committee ISO/TC 26, Copperandcopperalloys, and was circulated by the member bodies in November 1979. It has been approved by the member bodies of the following countries : Australia Belgium Bulgaria Canada China Czechoslovakia Egypt, Arab Rep. of Finland France

26、cted from table 4 and the figure. 4.3.3 Billets Billets shall be ordered by diameter and length. For diameters of billets up to and including 200 mm, a variation of + 3 mm is permissible. If closer tolerances on diameters are required, they shall be agreed between the interested parties. For diamete
27、rs of billets over 200 mm tolerances on diameter shall be as agreed between the interested parties. Billets may vary in length by f 2 % from the specified length unless otherwise agreed, and shall be straight within 4 mm per metre length. Unless other- wise specified, billets of phosphorus-deoxidize
28、d copper less than or equal to 100 mm in diameter may be supplied sheared at one end. The other end shall be flat. Billets over 100 mm in diameter shall be supplied with both ends flat. Billets shall not be cupped except by specific agree- ment at the time of purchase. 4.3.4 Other shapes Other shape
29、s not dealt with in 4.3.1 to 4.3.3 are static and con- tinuously vertically cast wire bars, vertically and horizontally cast cakes and ingots. Variation from ordered size is permissi- ble within the limits shown in table 5. 4.4 Physical condition 4.4.1 Cathodes shall withstand ordinary handling with
30、out ex- cessive breakage or excessive separation of nodules and shall be reasonably free from all foreign material such as copper sulphate, dirt, grease and oil. 4.4.2 Cakes, billets and wire bars shall be substantially free from shrink holes, cracks, cold sets, pits, sloppy edges, con- cave tops an
31、d other similar defects in set or casting. These re- quirements do not apply to ingots and ingot bars in which physical defects are of minor consequence. 5 Marking All shapes intended for fabrication shall be permanently marked with the manufacturer s brand and furnace charge mark or pro- duction nu
32、mber. Ingots shall have a brand stamped or cast in, but need not have a furnace charge mark. 6 Lots The manufacturers should endeavour to arrange lots so that, as far as possible, each lot contains pieces from one furnace charge or production lot only. 7 Chemical analysis 7.1 Sampling for chemical a
33、nalysis Sampling shall be done in accordance with ISO/R 1811, where such procedures apply. 7.2 Methods of analysis The methods used for determining the copper content of cop- pers of 99,90 % purity or greater shall be in accordance with IS0 1553, and for coppers of less than 99,90 % purity the test
34、method shall be in accordance with IS0 1554. The copper content of Cu-OFE and Cu-PHCE shall be deter- mined by subtracting the total of the concentrations of im- purities determined from 100 %. The impurity total is defined as the sum of the seventeen elements in table 3. The analytical methods for
35、determining the impurities in Cu-OFE and Cu-PHCE shall, in all cases of disagreement, be as agreed be- tween the supplier, the purchaser and any mutually acceptable arbitrator.
