This publication presents performance specifications for single-strand unbonded post-tensioning tendons in prestressed concrete structures. Specifications are given for both tendons in normal and aggressive (corrosive) environments. A commentary to each section is also provided. Revisions include clearer guidelines on defining aggressive environments, acceptance criteria for prestressing strand, compliance standards for encapsulated assemblies, and general enhanced provisions for corrosion protection of unbonded tendons.
