8、 non-arsenical copper 1 Scope 1.1 This specification covers non-arsenical deoxidized copper for general use. NOTE a) The titles of standards referred to by number in the specification are given in appendix A. b) Requirements that must be specified by the purchaser, or that must be agreed between man
9、ufacturer and purchaser, are listed in appendix B. 2 Definition 2.1 For the purposes of this specification the following definition shall apply: cast or lot the product of one furnace or crucible melt, or the product of a number of furnace, or crucible melts where these are combined and mixed prior
10、to casting, or the product of a continuous melting furnace where the amount of metal tapped from the furnace without any further additions of metal to the charge exceeds one-third of the furnace capacity 3 Requirements 3.1 Chemical composition The material shall comply with the chemical requirements

13、ch case the maximum bismuth content shall be 0,001 5 %. 3.2 Certificate of analysis The manufacturer or supplier shall, if so specified by the purchaser, supply to the purchaser a copy of the analysis certificate of the copper in the lot. 3.3 Form The copper shall be supplied in cakes, slabs, billet
14、s, or other form as specified by the purchaser. 3.4 Freedom from defects The copper supplied shall be substantially free from physical defects such as shrink holes, cracks, cold sets, pits, raised edges, and other defects in set or casting. 3.5 Nominal dimensions and tolerances The purchaser shall s
15、pecify the nominal dimensions and the following tolerances shall then apply: In the case of cylindrical billets, the permissible variations from the nominal dimensions shall be as follows: Length : 3 % Diameter : up to 25 mm: 5 % Over 125 mm: 6 mm In cases of cakes or slabs horizontally or verticall
16、y cast, the permissible variations from the nominal dimensions shall be as follows: Up to and including 200 mm : 6 mm Over 200 mm : 3 % SANS 404:2009 Edition 2.2 5 3.6 Gassing test When tested in accordance with 5.2, the copper shall show no edge or surface cracking. 4 Sampling and compliance with t
17、he specification1)4.1 Sampling The following sampling procedure shall be applied in determining whether a lot complies with the requirements of the specification. The sample(s) so drawn shall be deemed to represent the lot: a) Sample for inspection. From the lot take at random a number of complete c
18、akes (or the other shapes in the lot) such that their combined mass is at least 1% of the total mass of the lot. b) Sample for testing. Obtain the sample for test in the form of a test bar or ingot cast while pouring the lot. Obtaining such a test sample shall be a matter of agreement between the pu
19、rchaser and the manufacturer or supplier, and where such a sample cannot be obtained the sample taken in accordance with (a) above shall be used as the test sample. 4.2 Compliance The lot shall be deemed to comply with the requirements of the specification if after inspection and testing the samples
20、 drawn in accordance with 4.1 are found to comply with the appropriate requirements of the specification. 5 Inspection and methods of test 5.1 Inspection Inspect the samples drawn in accordance with 4.1 for compliance with the relevant requirements of 3.3, 3.4, and 3.5. NOTE If the purchaser wishes
21、to inspect the material at the manufacturers works, he shall notify the manufacturer to that effect at the time of placing the order. In such cases the manufacturer shall afford the purchaser all reasonable facilities to satisfy himself that the material complies with the requirements of the specifi
22、cation. 5.2 Gassing test 5.2.1 Preparation of test specimens Cut a piece or pieces of suitable size from each sample ingot or other shape taken in accordance with 4.1, and cold-roll or draw them (after preliminary forging or hot-rolling if necessary) into strip or wire of thickness not greater than
23、3,25 mm and not less than 2,0 mm. Cut test specimens of convenient length from the strip or wire, draw-file or other-wise smooth the edges, and anneal them in hydrogen for half an hour at 800 C. 5.2.2 Close bending After cooling, bend the test specimen AB (see figure 1) by steadily applied pressure
24、or a succession of blows at right angles to the length AC and flatten it close until A assumes the position indicated by D. 1) This section applies to the sampling for inspection and testing before acceptance or rejection of single lots in cases where no information about the implementation of quali
25、ty control or testing during manufacture is available to help in assessing the quality of the lot. It is also used as the procedure for adjudicating in cases of dispute. SANS 404:2009 Edition 2.2 6 5.3 Sample for chemical analysis a) So take the sample for chemical analysis by drilling completely th
26、rough each sample ingot or other shape, taken in accordance with 4.1, that the drillings are representative of its average cross-section. Where the thickness is too great to permit drilling right through, drill the pieces from either side to a depth equal to half their thickness. Thoroughly clean th
27、e drill used for taking the sample. Do not use a lubricant in the operation, and keep the drillings as fine as possible. Treat the drillings carefully with a magnet to remove any particles of iron which may have been introduced in taking the sample. b) The thoroughly mixed drillings shall constitute
28、 the sample for chemical analysis and shall be taken as being representative of the lot. 5.4 Methods of test NOTE Any reliable method of chemical analysis may be used for determining the individual constituents of the alloy(s). Suitable methods2)are listed below and shall be the methods used in case
