1.1 This specification covers indented, low-relaxation steel wire for use in prestressed concrete.
1.2 The text of this specification contains notes or footnotes, or both, that provide explanatory material. Such notes and footnotes do not contain any mandatory information.
1.3 This specification is applicable for orders in either inch-pound units (as Specification A881) or in SI units (as Specification A881M).
1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets.
