2、ast revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers aluminum alloy sheets used inthe fabrication of corrugated aluminum pipe intended for usefo
3、r storm water drainage, underdrains, culverts, and similaruses. The material is furnished corrugated in cut lengths, anduncorrugated in coils and cut lengths.1.2 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard. Within the text, theSI units are shown
4、in brackets. The values stated in eachsystem are not exact equivalents; therefore, each system shallbe used independently of the other. Combining values from thetwo systems may result in nonconformance with the standard.1.3 This standard does not purport to address all of thesafety concerns, if any,
5、 associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Chemical Composition5.1 The sheet material
16、 shall conform to the chemical com-position limits in Specifications B 209 B 209M.6. Mechanical Requirements6.1 The sheet material shall conform to the requirements formechanical properties specified in Specification B 209B 209M, when tested prior to corrugating or other fabrica-tion.NOTE 2Sheet mat
17、erial tested after corrugating and other fabricatingshould conform to the specified tensile and yield strength requirements,but due to cold working, conformance to the elongation requirements maynot be obtained.7. General Requirements7.1 Aluminum alloy sheets or coils supplied under thisspecificatio
18、n shall conform to the applicable requirements ofSpecification B 209 B 209M (as appropriate) for alclad alloy3004-H34 for riveted pipe or alclad alloy 3004H32 for helicalpipe.8. Dimensions and Tolerances8.1 Sheet thickness shall conform to dimensions prescribedin Table 1.8.2 The thickness of claddin
19、g shall be as specified inSpecification B 209 B 209M.8.3 Permissible variations in flat width, length and square-ness shall be in accordance with ANSI H35.2 H35.2M.8.4 Corrugations shall form smooth continuous curves andtangents. The dimensions of the corrugations shall be inaccordance with Table 2.
20、8.5 Covering width of corrugated sheet shall be in accor-dance with Table 3. Covering width is the distance between thecrests of the extreme corrugations. There is no establishedtolerance for overall width since the covering width and lipdimensions are the governing factors for the formed product.Th
21、e lip dimension of corrugated sheet shall be in accordancewith Table 4. This dimension is measured along the radialcurvature from the crest of the corrugation to the edge of thesheet.9. Sampling and Testing9.1 Sampling and testing shall be according to SpecificationB 209 B 209M. The manufacturer sha
22、ll make adequate testsand measurements to ensure that the material produced com-plies with this specification.9.1.1 Test results including chemical composition, mechani-cal properties, and cladding thickness shall be maintained bythe sheet manufacturer for seven years and shall be madeavailable to t
23、he fabricator and purchaser upon request, forexamination at the manufacturers facility unless otherwiseagreed upon.9.2 The fabricator or the purchaser may make such tests asare necessary to determine the acceptability of the material orto verify the correctness of a certification.9.3 Mechanical prop
24、erties shall be determined on sheetprior to corrugating or other fabricating, except tests may bemade after fabrication by the purchaser for tensile and yieldstrengths.10. Rejection10.1 Material tested by the purchaser and found not con-forming to this specification may be rejected.11. Certification
25、11.1 When specified in the purchase order or contract, amanufacturers certification shall be furnished to the purchaserof the sheet (fabricator) or to the purchaser of the finished pipestating that samples representing each lot have been tested andinspected in accordance with this specification and
26、the require-ments have been met. When specified in the purchase order orcontract, a report of the mechanical test results and thechemical composition limits shall be furnished.NOTE 3As the identity of the sheet is not maintained from the originalingot production, if numerical results are required by
