    This specification covers filled epoxy-coated seven-wire prestressing steel strands with protective fusion-bonded epoxy coating applied by the electrostatic deposition method. This specification also covers relaxation loss limits for filled epoxy coated strands. Prestressing steel strands shall be free of contaminants such as oil, grease, or paint. Steel strand surfaces shall be cleaned to meet coating requirements, such as coating thickness, coating continuity, coating adhesion, coating composition, and coating bond with concrete or grout. Smooth or grit-impregnated coating shall be applied by the electrostatic deposition method or other method that will meet the coating requirements. Pullout tests shall be performed three times annually or maybe repeated if the coating failed to meet the requirements.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification covers seven-wire steel prestressing strand with protective fusion-bonded epoxy powder coating applied by the electrostatic deposition method or other suitable method, with the interstices of the seven wires filled with epoxy to minimize migration of corrosive media, either by capillary action or other hydrostatic forces.

    Note 1: The manufacturer as identified throughout this specification is the coating applicator.

    1.2 A supplementary requirement (S1) is provided for use where bond strength testing of 0.600-in. [15.24-mm] diameter grade 270 [1860] epoxy-coated strand for applications in prestressed ground anchors is required by the purchaser. The supplementary requirement applies only when specified in the purchase order or contract.

    1.3 Requirements for epoxy powder coatings are contained in Annex A1.

    1.4 The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables) shall not be considered as requirements of the specification.

    1.5 This specification is applicable for orders in either inch-pound units (as Specification A882) or SI units [as Specification A882M].

    1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the specification.

    1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
