TS EN 17678-2

TS EN 17678-2 focuses on how the competence of personnel installing post-tensioning kits for prestressing structures is assessed and verified. It sets out a scheme for checking the knowledge, skills and practical readiness of installers, and frames the roles of training providers, assessment bodies and, where applicable, certification bodies.

Why competence is treated as a separate subject

Post-tensioning is a specialised structural technique used to improve the load-bearing behaviour of concrete and similar structural members. Installing these kits involves understanding anchors, tendons, stressing equipment and the correct sequence of operations. Because a small installation error can affect how the system performs, it matters not only that personnel are experienced, but also that their competence is assessed in a defined and verifiable way. This standard addresses that verification framework.

How the standard positions the organisations involved

The document brings together the parties that may be involved in personnel assessment: training providers, bodies carrying out the assessment, and optional certification bodies. It also notes that a national annex may amend the document where indicated in the text. The minimum competence and experience requirements themselves are not set out here; they are given in EN 17678-1. In that sense, EN 17678-2 is best understood as a competence-assessment arrangement rather than an installation manual.

• Defines the scheme for assessing and verifying installer competence.
• Addresses the roles of training providers, assessment bodies and possible certification bodies.
• Does not contain the minimum competence and experience requirements for installers; those are in EN 17678-1.
• May be amended by a national annex where indicated.
