7、worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented
8、 on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are draft
9、ed in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Stan
10、dard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 115 was prepared by

12、ingots for remelting Classification and composition 1Scope This International Standard defines the requirements for grades of unalloyed aluminium ingots intended for remelting. It specifies the classification and designation applicable to these grades, the conditions in which they are produced, thei
13、r properties and the marks by which they are identified. 2Order The order, in the form agreed upon between supplier and purchaser, shall contain the following information: a)designation of the unalloyed aluminium in accordance with this International Standard or the customer code after agreement bet
14、ween supplier and purchaser; b)specification of the form of the products, including mass and dimensions of individual ingot and bundles; c)quantity: mass, in tonnes (quantity tolerances if required); d)any requirements for certificates of conformity, test and/or analysis reports or inspection certif
15、icates; e)any additional requirements agreed between supplier and purchaser. If special requirements, which differ from requirements specified in this International Standard, are specified in the order between supplier and purchaser, then these special requirements shall apply. 3Requirements 3.1Prod
16、uction and manufacturing processes Unless otherwise specified on the order, the production and manufacturing processes shall be left to the discretion of the manufacturer. Unless otherwise specified on the order, no obligation shall be placed on the manufacturer to use the same processes for subsequ
17、ent and similar orders. 3.2Quality control The supplier shall be responsible for carrying out all inspection and tests required by this International Standard and additional requirements, prior to shipment of the product. If the purchaser wishes to inspect the product at the suppliers works, the pur
18、chaser shall stipulate this at the time of placing the order. 3.3Chemical composition Each grade of unalloyed aluminium, including refined aluminium, with a specified minimum aluminium content shall be in accordance with the designations and chemical composition given in Table 1. Each grade of unall
19、oyed aluminium without a specified minimum aluminium content shall be in accordance with the designations and chemical compositions given in Table 2. -,-,- ISO 115:2003(E) 2 ISO 2003 All rights reserved The compositions, except that for aluminium, shown in Table 1 and Table 2 are given in maximum ma
20、ss percentage. For the interpretation of the results of chemical analysis, the number representing the result of the determination of an element content shall be rounded to the same number of decimal places as the corresponding number in this International Standard. The writing rules for designation
21、s and chemical compositions shall be applied in accordance with Annex A. If the purchaser requires content limits for elements not specified in this International Standard, these limits shall be stated on the order, after agreement between supplier and purchaser. 3.4Freedom from contamination and ha
22、zardous materials The ingots shall be free from asbestos and other hazardous foreign material and show no indication of increased radioactivity.
