This specification covers deformed and plain austenitic and duplex (austenitic/duplex) stainless steel bars for concrete reinforcement proposed to be used in applications requiring corrosion resistance, controlled tensile properties or controlled magnetic permeability. For each specimen, one tension test, one bend test, if required, and one set of dimensional property tests shall be made. If the results of the test fail to meet the specified minimum requirements, a retest shall be permitted on two random specimens for each original tension specimen failure from the lot. If a specimen fails a bend test due to reasons other than mechanical or flaws, a retest shall be permitted on two random specimens from the same lot.
