    A LEGAL BASES AND GENERAL CONDITIONS

    A.1 This European Technical Approval is issued by Stra in accordance with: Council Directive 89/106/EEC of 21 December 1988 on the approximation of

    laws, regulations and administrative provisions of Member States relating to construction products1, modified by Council Directive 93/68/EEC2 and Regulation (EC) N 1882/2003 of the European Parliament and of the Council3 ;

    dcret n92-647 du 8 juillet 19924 concernant l'aptitude l'usage des produits de construction ;

    Common Procedural Rules for Requesting, Preparing and the Granting of European Technical Approvals set out in the Annex to Commission Decision 94/23/EC5 ;

    ETAG 013, Edition June 2002, Post-Tensioning Kits for Prestressing of Structures.

    A.2 Stra is authorised to check whether the provisions of this European Technical Approval are met. Checking may take place in the manufacturing plant(s). Nevertheless, the responsibility for the conformity of the products to the European Technical Approval and for their fitness for the intended use remains with the holder of the European Technical Approval. A.3 This European Technical Approval is not to be transferred to manufacturers or agents of manufacturers other than those indicated on page 1, or manufacturing plants other than those indicated on page 1 of this European Technical Approval. A.4 This European Technical Approval may be withdrawn by Stra, in particular pursuant to information by the Commission according to Article 5(1) of Council Directive 89/106/EEC. A.5 Reproduction of this European Technical Approval including transmission by electronic means shall be in full. However, partial reproduction can be made with the written consent of Stra.

    B SPECIFIC CONDITIONS OF THE EUROPEAN TECHNICAL APPROVAL

    B.1 DEFINITION OF PRODUCTS AND INTENDED USE

    B.1.1 Definition of Products This European Technical Approval applies to a kit: DYWIDAG External Strand Post-Tensioning System

    consisting of 3 to 37 strands. The DYWIDAG post-tensioning kit is designed for internal unbonded and external prestressing. The prestressing tendon consists of a bundle of 7-wire strands, anchorages, deviators, sheathing and corrosion protective compounds.

    - The strands are defined in the prEN 10138-3: Prestressing steels Strand as 0.6 normal and super strand, i.e. with 15.3 and 15.7 mm nominal diameter, with a nominal tensile strength of 1770 or 1860 N/mm, coded Y1770S7 15.3 (or 15.7) or Y1860S7 15.3 (or 15.7), respectively, referred to as the tensile element.

    - As long as EN 10138 is not implemented 7-wire strands in accordance with national provisions shall be used.

    - Stressing (active) anchorages and fixed (passive) anchorages consisting of an anchor plate with connection tube, steel trumpet, plastic

    insert and wedge plate, or

    consisting of a cast iron anchor body with a HDPE-trumpet and a wedge plate.

    - Sheathings are made of plastic (polyethylene, HDPE). - Deviators are specific elements at given locations in the structure along the tendon.

    These are generally made of steel tubes (straight or prebent) placed inside the concrete structure or construction steel saddles applied to the structure.

    - Bursting reinforcement (helix and stirrups), for the concrete confinement at anchorages to ensure local prestressing force transfer into the concrete structure.

    - The corrosion protecting compound can be a flexible compound with a wax base (in accordance with Annex C.4.2 of ETAG 013) for external and internal unbonded use, or a cement based grout (in accordance with EN 447) for rigid injection for external use only.

    Steel and plastic tubes, the ordinary reinforcement for bursting reinforcement, grouting products are covered by European or national provisions thus they are not described in this ETA. However, they can be used for the prestressing kit.

    Version of the 27th June 2013

    B.1.2 Intended use The DYWIDAG internal unbonded and external strand post-tensioning system (in the following PT system) has been developed to be used for:

    new structures repairing and strengthening existing structures

    exposed to effects from gravity and live loads, climate exposures, imposed sets of deformations. If used for external prestressing this PT system is meant for concrete structures/members with a tendon path situated outside their cross section but inside their envelope. It may also be employed in structures made of other materials, e.g. masonry, steel, cast iron, timber or combinations of several materials (see Annex 15). In case of use with other materials than concrete, dimensions and force transfer shall be designed according to the relevant Eurocodes or national regulations valid in place of use.
