European foreword

and related products”, the secretariat of which is held by SN.
This document is currently submitted to the CEN Enquiry.

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 a European standard on competence of personnel is:

— safety and quality considerations during the installation of the 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, “Requirements for the installation of post-tensioning kits for prestressing

of structures and qualification of the specialist company and its personnel”.

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 14649 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, “Execution of

concrete structures”.

Part 1 of this document deals with the minimum competence personnel dealing with PT installations shall

possess and on the tasks the personnel are qualified to undertake.

prEN 17678-2 gives the framework for how to assess the competence of PT personnel and issuing

certificates to candidates fulfilling the requirements.

Additional requirements to those given in this document may be specified in the execution specification

or in a national annex to this document.

in the stressed tendon and to transmit it to the concrete;

— Bursting reinforcement. The reinforcement in the anchorage zone to resist transverse tensile forces due

to the introduction of prestressing force;
— Coupler. A device to join tendons;

— Duct (sheathing). An enclosure in which the prestressing steel is placed and which temporarily or
