The tendon is using 7-wire prestressing steel strand as tensile elements. Only 7-wire prestressing steel strands as defined in EAD 160004-00-0301, clause 1.1, in terms of geometry and characteristic force are covered by this EAD. No essential characteristics are assessed for tensile elements in the EAD. 1.1.2.2 Structural anchorage components Structural anchorage components are for load transfer from the tendon to the structure and for load transfer from the tendon to the rock or soil at the dead-end anchorage (anchorage unit and compression pipe), where relevant. Structural anchorage components made of steel are covered in this EAD. Structural anchorage components for load transfer to the structure at the stressing end anchorage include: - Anchor head; - Wedges; - Anchor plate; - Local anchorage zone reinforcement, if required; - Electrically insulating plate, placed such as to electrically insulate the tendon from the structure and ground (PLC1 and PLC2). Structural anchorage components for load transfer from the tensile elements to the rock or soil at the dead-end anchorage (compression pipe anchors only) include: - Anchorage unit (for load transfer from tensile elements to compression pipe): Proprietary mechanical components such as anchor head and wedges or compression fittings attached to tensile elements may be used in anchorage unit for load transfer from tensile element to compression pipe or, alternatively, load transfer may be provided by bond through cement grout inside the anchorage unit; a combination of the two alternatives may also be used; - Corrugated compression pipe. No additional structural anchorage components are necessary for load transfer from the tensile elements to the ground in conventional bond type anchors.
Under the CPR, harmonised technical specifications are harmonised European product standards (hENs) established by CEN/CENELEC2 or European Assessment Documents (EADs) produced by the European CPR指令認證的依據是建築指令歐盟協調標準或歐盟評估檔（EADs）
European Organisation for Technical Approvals (EOTA) as the basis for issuing ETAs for products not covered by hENs.The harmonised technical specification for a product defines EEA-wide methods of assessing and declaring 對於沒有被協調標準完全覆蓋的建築產品的認證，可以通過EOTA機構核發ETA認證證書（等同於CE認證書）。
六、歐盟公告NB機構&TAB機構-捷克TZUS (NB1020)介紹
TZUS是歐盟公告號機構，其歐盟公告號為1020(Notified Body 1020-NB1020)。可以根據歐盟相關規定來簽發CE證書。 TZUS同時也是ETA(European Technical Approval)的認證委員之一，可以根據相關法規來簽發ETA證書。
