Appendix D2-VIII, paragraph D2-VIII-1555), the criteria for failure of tests should be the same strength requirement as in items (b) and (c) above. e. The actual yield strength (fy_actual) of deformed reinforcing bar should be determined by either of the methods listed below: (1) the offset method, using an offset of 0.2 percent in accordance with ASTM A370-18, “Standard Test Methods and Definitions for Mechanical Testing of Steel Products” (Ref. 54), or (2) the yield point by the halt-of-force method, provided that the reinforcing bar has a sharp-kneed or well-defined yield point. f. Additional testing and evaluation should be performed for impactive and impulsive loading conditions, where the mechanical splices or mechanical headed bar systems are subjected to loading that causes high strain rate. 12. CC-4480 Protection of Post-Tensioning Anchorages and Prestressing Steel ISI of Class CC reinforced concrete containments and prestressed concrete containments with ungrouted tendons should meet the requirements of Subsection IWL of Section XI, “Rules for Inservice Inspection of Nuclear Power Plant Components,” of the ASME B&PV Code, as incorporated by reference in 10 CFR 50.55a, “Codes and Standards.” ISI of prestressed concrete containment with grouted tendons should be in accordance with RG 1.90. 13. CC-5210 General [Concrete Construction Examination] The provisions of CC-5210 should be supplemented by an inspection to ensure that only those embedments shown on the construction drawings (except minor embedments such as rebar supports and form ties) or covered by documented field changes and later placed on the as-built drawings, remain in the form after the concrete is placed. Additionally, the inspection should ensure that hollow tubes and pipe DG-1372, Page 21 sections used as support systems or for other construction convenience, if left embedded in the concrete, are filled with concrete or grout as appropriate. 14.
