European foreword
This document (prEN 10369-1:2019) has been prepared by Technical Committee CEN/TC 459/SC 4
“Concrete reinforcing and prestressing steels”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of
EU Construction Products Regulation (EU 305/2011).
For relationship with EU EU Construction Products Regulation (EU 305/2011), see informative
Annex ZA, which is an integral part of this document.
prEN 10369 consists of three parts under the general title “Prestressing steels — Protected and
sheathed strands for prestressing”:
— Part 1: General requirements
— Part 2: Sliding strands
— Part 3: Adherent strands
Whenever approved, the publication of this series of standards will wait until EN 10138-1 and
EN 10138-3 and EN 10337 are approved.
1 Scope
This document specifies the requirements for uncoated high strength steel strands or zinc or zinc alloy
1)
coated high strength steel strands, encapsulated with a protection product and a sheath .
The intended use of these products is mainly the prestressing of concrete.
NOTE These products can also be used in other stress applications in the construction field (e.g. stay cables
for bridges) where the protection of the products is not removed in use.
The standard applies only to products as supplied by the producer.
