This publication provides specific technical requirements for the approval and acceptance of post-tensioning systems.  Standards and performance requirements for prestressing materials, bearing plates, wedge plates, connections, and sheathing are discussed in detail.  Qualification tests and acceptance criteria are presented for each of the individual components as well as for the complete system.  A system approval summary outlines the test requirements and number of successful tests necessary for approval of a post-tensioning system.  This document is not intended to cover unbonded monostrand post-tensioning systems, which have their own separate specification.
