scope:

These specifications provide performance criteria for materials and detailed recommendations for the fabrication and installation of unbounded single strand tendons specifically used in any application of slab-on-ground construction using unbounded post-tensioned reinforcement. Specifications are presented for both "standard" and "encapsulated" unbounded single strand tendon systems.

The more restrictive materials, fabrication, and construction requirements for tendons used in aggressive environments referred to as encapsulated tendons in this specification are essential to the long-term durability of the post-tensioning (PT) system when used in foundations that are exposed to or constructed in these environments.

Where appropriate, a commentary follows most major sections of the document.
