1 Scope This standard specifies the terms and definitions, symbols and interpretations, components and materials, technical requirements, inspection rules, marking, packaging, transport and storage, inspection and monitoring of external prestressing tendons (hereinafter referred to as external tendon). This standard is applicable to newly-built prestressed concrete girder bridge structures. Reference may be made to this standard for the external tendons used for maintenance and reinforcement of existing bridge structures and for other structures. 2 Normative references The following referenced documents are indispensable for the application of this document.
