2、t for ResaleNo reproduction or networking permitted without license from IHS-,-,-IS0 9724:1992(E) Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally ca
3、rried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the wo
4、rk. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Inter- national Standard requi
5、res approval by at least 75% of the member bodies casting a vote. International Standard IS0 9724 was prepared by Technical Committee ISO/TC 155, Nickel and nickel alloys, Sub-Committee SC 2, Wrought and cast nickel and nickel alioys. Annex A forms an integral part of this International Standard. 0

13、ses of this International Standard, the following definitions and those for nickel and nickel alloys in IS0 6372-l and for wire and drawing stock in IS0 6372-3 apply. 3.1 heat: The product of a furnace melt or a number of melts that are mixed prior to casting. 3.2 lot: Wire or drawing stock of the s
14、ame diameter from the same heat, heat treated together or se- quentially heat treated in a continuous furnace, but in no case for longer than 16 h of production. 4 Alloy identification For the purposes of this International Standard, the principles for alloy identification in ISO/TR 7003 and ISO/TR
15、9721 apply. 5 Ordering information Orders for wire or drawing stock according to this International Standard shall include the following information. 5.1 The number of this international Standard. 5.2 Quantity (mass or number of pieces). 5.3 Alloy Identification (see table 1). NOTE 1 For alloy ident
16、if;cation, either the number or the description may be used. 1 Copyright International Organization for Standardization Provided by IHS under license with ISONot for ResaleNo reproduction or networking permitted without license from IHS-,-,-IS0 972 b) surface finish (see 6.1.3 and 6.2.2); c) technol
17、ogical tests: - torsion test (see 9.3.1), - reverse bend test (see 9.3.2), - wrapping test (see 9.3.3); d) purchaser or third-party inspection (see clause 1 I); e) declaration of conformity (see clause 12). 6 Requirements 6.1 Requirements for wire 6.1.1 Composition Heat analysis shall meet the compo
18、sition limits specified in table 1. The composition limits do not preclude the possible presence of other elements that are not specified. If the purchasers requirements necessitate limits for any other element that is not specified, these shall be agreed between the purchaser and the supplier. The
19、percentage content of elements shown as “re- mainder” shall be calculated by difference from 100 %. 6.1.2 Tensile properties Wire shall have the tensile properties specified in table 2. Where tensile properties are not specified in table2, these shall be agreed between the pur- chaser and the suppli
20、er. 6.1.3 Surface quality Unless otherwise specified, surfaces shall have a tightly adherent oxide or shall be mechanically or chemically cleaned at the option of the supplier. Wire shall be clean and free from surface imperfections. NOTE 2 Where appropriate, the acceptance criteria should be agreed
21、 between the purchaser and the supplier. 6.1.4 Dimensional tolerances The diameter of round wire shall not differ from that specified by more than the tolerances specified in table 3. Out-of-roundness shall not exceed one-half of the total permissible variations specified in table 3. Tolerances for
22、cross-sections other than round shall be agreed between the purchaser and the supplier. 6.2 Requirements for drawing stock 6.2.1 Composition Heat analysis shall meet the composition limits specified in table 1. The composition limits do not preclude the possible presence of other elements that are n

32、 7802. 9.4 Rounding-off For the purpose of determining compliance with the specified limits of the properties listed below, an observed value or calculated value shall be rounded as follows. When the figure immediately after the last figure to be retained is lower than 5, the last figure to be retai
33、ned remains unchanged. When the figure immediately after the last figure to be retained is 5 or greater, the last figure to be retained is increased by one.

35、 product has been withdrawn by the sup- plier. If the test pieces from both these additional samples pass the tests, the lot represented by the test samples shall be deemed to comply with the requirements of this International Standard. If the test pieces from either of these additional samples fail
36、, the lot represented by these samples shall be deemed not to comply with the requirements of this International Standard. 10 Marking Each coil of wire or drawing stock shall be marked on a securely attached durable label, with the num- ber of this International Standard, the alloy identifi- cation
37、(either the number or the description), the heat number and the manufacturers name. 11 Purchaser and third party inspection On-site inspection of wire or drawing stock shall be in accordance with agreements made between the purchaser and the supplier as part of the purchase contract. 3 Copyright Int
