1、Designation:A1055/A1055M16Standard Specification forZinc and Epoxy Dual-Coated Steel Reinforcing Bars1This standard is issued under the fixed designation A1055/A1055M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last r
2、evision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers deformed and plain steelreinforcing bars with a dual coating of zinc-alloy followed byan epoxy coating
3、 applied by the electrostatic spray method.1.2 The zinc-alloy coating is produced as one of two types:zinc-alloy applied by the thermal spray method(Type I)orzinc-alloy applied in accordance with Specification A1094/A1094M(Type II).NOTE1The coating applicator is identified throughout this specifica-
4、tion as the manufacturer.1.3 Requirements for the zinc coating are contained inTable 1.1.4 Requirements for epoxy powder coatings are containedin Annex A1.1.5 Guidelines for construction practices at the job-site arepresented in Appendix X1.1.6 The text of this specification references notes andfoot
5、notes which provide explanatory material.These notes andfootnotes(excluding those in tables and figures)shall not beconsidered as requirements of the specification.1.7 This specification is applicable for orders in eitherinch-pound units as Specification A1055 or SI units asSpecification A1055M.1.8
6、The values stated in either inch-pound units or SI unitsare to be regarded as standard.Within the text,the SI units areshown in brackets.The values stated in each system may not beexact equivalents;therefore,each system must be used inde-pendently of the other,except as specifically noted in Table 2
7、.Combining values from the two systems may result in non-conformance with this specification.1.9 This specification does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this specification to establishappropriate safety and health
