9、ritish Standard has been prepared under the direction of the Packaging and Freight Containers Standards Policy Committee. It supersedes BS 4853:1972 which is withdrawn and applies to tensional steel strapping suitable for lifting purposes and revises the tensile strengths of other strappings. This s
10、tandard specifies tolerances; specific dimensions for strapping are available from manufacturers. Various finishes are listed in Appendix A but it should be noted that, in addition, other finishes may be obtained which may improve the material for a particular purpose. The finish may affect the mech
11、anical properties and the manufacturers advice should therefore be obtained when finishes other than those listed in Appendix A are selected. Users of tensional steel strapping are recommended to consult BS 1133-15 which gives guidance on its use. A British Standard does not purport to include all t
12、he necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii
13、, pages 1 to 4, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover. Licensed Copy: sheffieldun sheffieldun, na, Fri Dec 01 07:50:47 GMT+00:00 2006
14、, Uncontrolled Copy, (c) BSI BS 4853:1989 BSI 11-19991 1 Scope This British Standard specifies tolerances and tensile strengths for cold rolled flat strip, hot rolled flat strip and round, oval and flat wire tensional steel strapping for general packaging purposes. It also specifies tolerances, tens
15、ile strengths and the joint strength for cold rolled flat strip suitable for lifting and lashing purposes. Guidance on the surface finishes available is given in Appendix A. NOTEThe title of the publication referred to in this standard is given on the inside back cover. 2 Definitions For the purpose
16、s of this British Standard the following definitions apply. 2.1 tensional steel strapping a specially processed high tensile steel in flat strip, or round, oval or flat wire, applied to packages by machines and tied or sealed while under tension NOTEFlat strapping specifically for lifting and lashin
17、g purposes is available and can be identified by means of special marking (see clause 6). 2.2 flat strapping cold or hot rolled steel strip which has dressed edges for safe handling 2.3 wire strapping steel wire which is either round, oval or flat 2.4 oval wire steel wire which has an elliptical cro
18、ss section 2.5 round wire steel wire which has a circular cross section 2.6 flat wire steel wire which has a rectangular cross section with rounded corners 3 Tolerances 3.1 Cold rolled flat tensional steel strapping The tolerances of cold rolled tensional steel strapping in flat strip form shall be
19、as follows: The tolerances of cold rolled flat tensional steel strapping for lifting and lashing purposes shall be as follows: 3.2 Hot rolled flat tensional steel strapping The tolerances of hot rolled tensional steel strapping in flat strip form shall be as follows: a) width 0.15 mm; b) thickness 0
20、.05 mm. 1) width 0.13 mm; 2) thickness a) width 1.20 mm; b) thickness 0.10 mm. 0 0.076+ mm.

21、 strapping in round wire form shall be as follows: 3.4 Oval wire tensional steel strapping The tolerances of tensional steel strapping in oval wire form shall be as follows: 3.5 Flat wire tensional steel strapping The tolerances of tensional steel strapping in flat wire form shall be as follows: 4 T
22、ensile strength NOTE 1For all types of tensional steel strapping the minimum tensile strength S (in N/mm2) is calculated as follows: where NOTE 2The maximum cross-sectional area is calculated using the maximum dimensions, i.e. the nominal dimensions plus the tolerances. The various minimum tensile s
23、trengths quoted in 4.1 to 4.6 result from specific manufacturing techniques, some of which are designed to accentuate properties other than or in addition to tensile strength. 4.1 Cold rolled flat tensional steel strapping The three minimum tensile strengths of cold rolled tensional steel strapping
24、in flat strip form shall be as follows: 4.2 Cold rolled flat tensional steel strapping for lifting and lashing The minimum and maximum tensile strengths of cold rolled tensional steel strapping in flat strip form for lifting and lashing purposes shall be as follows: 4.3 Hot rolled flat tensional ste
