Unbonded Tendon Plant Certification Program
Launched in 1989, the Post-Tensioning Institute (PTI) program for
Certification of Plants Producing Unbonded Single Strand Tendons has
been developed to provide independent certification of a plant's
extrusion and/or fabrication process and its capability to produce
standard and/or encapsulated unbonded single strand tendons. This
certification program also includes evaluation of calibration practices
for jacks and gauges used for stressing single strand tendons. The
program is applicable to all facilities whether fixed or mobile.
The certification of a plant under this program indicates that the
plant and the personnel are capable of producing unbonded single strand
tendons in conformance with the Post-Tensioning Institute's
Specification for Unbonded Single Strand Tendons. The certification
program extends only to the process for extrusion and/or fabrication
procedures and materials within the examined plant, and is expressly
not intended to cover procedures or events subsequent to shipment of
tendons to the job site.
