Introduction
The market for the post-tensioning (PT) kits exists worldwide but the first area of concern is Europe.
The main motivating factor for creating this document on competence of personnel is:
— safety and quality considerations during the installation of the PT kits;
— safeguarding the integrity of structures during their service life;
— facilitating free movement of PT personnel, both between PT specialist companies and member
states.
The requirements for the competence and assessment of prestressing personnel are based on the
experience of CWA 14646:2003 [2].
The CWA was initiated by the PT providers and the CEN workshop represented all groups of stakeholders
related to the installation of PT kits.
As CWA 14646 has expired and to fill this gap, an initiative by the same group of stakeholders was taken
to replace and update the provisions on competence in CWA 14646 with this document.
This document supplements the general requirements of personnel given in EN 13670.
Part 1 of this document deals with the minimum competence personnel working with PT installations
shall possess, and with the tasks the personnel is qualified to undertake.
Part 2 of this document gives the framework for how to assess the competence of PT personnel and issue
certificates to candidates fulfilling the requirements.
Additional requirements and requirements beyond the minimum formulated in this document may be
specified in a project specification or in a national annex to this document.
