9、IS0 6934-4:1991(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 carried out through IS0 technical committees. Each member body interested in a su
10、bject 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 pari in the work. IS0 collaborates closely with the International Electrotechnical Commission
11、 (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 requires approval by at least 75% of the member bodies casting a vote. International
12、 Standard IS0 6934-4 was prepared by Technical Committee ISO/TC 17, Steel, Sub-Committee SC 16, Steels for the reinforcement and prestressing of concrete. IS0 6934 consists of the following parts, under the general title Steel for the prestressing of concrete: - Part I: General requirements - Part 2
13、 : Cold-drawn wire - Pari 3: Quenched and tempered wire - Part 4: Strand - Part 5: Hot-rolled steel bars with or without subsequent processing 8 IS0 1991 All rights reserved.

16、of IS0 6934 specifies requirements for high tensile steel strand which has been given a stress relieving heat treatment according to the general requirements specified in IS0 6934-1. The strand may contain either 2, 3, 7 or 19 individual wires. 2 Normative reference The following standard contains p
17、rovisions which, through reference in this text, constitute provisions of this part of IS0 6934. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this part of IS0 6934 are encouraged to investi- gate the possibilit
18、y of applying the most recent edi- tion of the standard indicated below. Members of IEC and IS0 maintain registers of currently valid International Standards.

19、6934, the defi- nitions given in IS0 6934-1 and the following defi- nition apply. 3.1 compacted strand: A strand which has been compressed (e.g. by cold working afler stranding) and given a stress-relieving treatment before wind- ing into coil form. 4 Conditions of manufacture 4.1 Steel The strand s
20、hall be manufactured from high tensile steel wire in accordance with IS0 6934-1. 4.2 Stress-relieving heat treatment The strand shall be subjected to a low temperature heat treatment as a continuous linear process by uncoiling and running the strand through a suitable form of heating (see IS0 6934-1
21、). The strand shall be rewound into coils or onto reels having a core diameter which is sufficiently large to ensure that the strand shall be reasonably straight when uncoiled (see 8.2). Strand forming operations and the stress relieving treatment shall ensure that the wires do not unravel when the
22、strand is cut. However, if unravelled, it shall be possible to put them back into position without difficulty. 4.3 Compacted strand The 7-wire strand shall comply with 4.4 before drawing. After drawing and stress-relieving treatment, the strand shall have a pitch of 14 to 18 times the nom- inal stra
23、nd diameter. 4.4 Welds 4.4.1 2-wire and 3-wire strand The wire from which the strand is fabricated shall not contain welds. 1 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/25/2007 02:0
