1、Designation:B744/B744M15Standard Specification forAluminum Alloy Sheet for Corrugated Aluminum Pipe1This standard is issued under the fixed designation B744/B744M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revis
2、ion.A number in parentheses indicates the year of last reapproval.A superscript epsilon()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 usefor storm water
3、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 in brackets.The value
4、s 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,associated with its use.It
5、 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.Referenced Documents2.1 ASTM Standards:2B209 Specification for Aluminum and Aluminum-AlloySheet and PlateB209M Specificat
