1、Designation:A 885/A 885M 96(Reapproved 2002)Standard Specification forSteel Sheet,Zinc and Aramid Fiber Composite Coated forCorrugated Steel Sewer,Culvert,and Underdrain Pipe1This standard is issued under the fixed designationA885/A885M;the number immediately following the designation indicates the
2、yearof original adoption or,in the case of revision,the year of last 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.Scope1.1 This specification covers steel sheet,composite coated,us
3、ed in the manufacture of corrugated pipe used for sewers,culverts,and underdrains.The composite coating consists of alayer of aramid nonwoven fabric bonded by molten zinc to thesteel sheet,to act as a bonding medium for asphalt coatingslater applied to fabricated products.Material for this use isfur
4、nished in coils,flat in cut lengths,and corrugated in cutlengths.1.2 The values stated in either inch-pound units or SI unitsare to be regarded separately as the standard.Within the text,the SI units are shown in brackets.The values stated in eachsystem are not equivalents;therefore,each system must
5、 beused independent of the other.Combining values from the twosystems may result in nonconformance with the specification.1.3 This specification and some referenced specificationsare expressed in both inch-pound and SI units.If the orderspecifies the applicable“M”specification designation,theproduct
