1、Designation: A 857/A 857M 07Standard Specification forSteel Sheet Piling, Cold Formed, Light Gage1This standard is issued under the fixed designation A 857/A 857M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last re
2、vision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification covers cold-formed, lig
3、ht gage carbonsteel sheet piling of structural quality for use in the construc-tion of shore walls, trench shoring, wingwalls, bulkheads, andlike applications.1.2 The nominal thickness of material furnished under thisspecification shall be 0.25 in. 6.4 mm or less.1.3 When the sheet piling is to be w
4、elded, it is presupposedthat a welding procedure suitable for the grade of steel andintended use or service will be used. See Appendix X3 ofSpecification A 6/A 6M for information on weldability.1.4 The values stated in either inch-pound units or SI unitsare to be regarded as the standard. Within the
5、 text, the SI unitsare shown in brackets. The values stated in each system are notexact equivalents; therefore, each system must be used inde-pendently of the other. Combining values from the two systemsmay result in nonconformance with the specification.2. Referenced Documents2.1 ASTM Standards:2A

Chemical Composition5.1 The chemical composition of the steel on heat analysisshall conform to the requirements listed in Table 1
10、.6. Tension Test6.1 The source material or the sheet piling as provided in 6.2and 6.3, as represented by the test specimens, shall conform tothe tensile requirements for the grade specified as listed inTable 2.6.2 Sheet and strip source materials shall be tested inaccordance with the requirements of
11、 Specification A 1011/A 1011M or A 1018/A1018M. The test specimens shall betaken from the source material or from the sheet piling. If testspecimens are obtained from the sheet piling, they are to betaken from a nondeformed area.6.3 Plate source material shall be tested in accordance withthe require
12、ments of Specification A 6 /A 6M, except that thetest specimen may be taken such that the longitudinal axis ofthe specimens are parallel to the final direction of rolling of thematerial. The test specimens shall be taken from the source orfrom the sheet piling on a nondeformed area.1This specificati
