Number of Tests and Retests12.1 In the case of sheet or strip supplied in coil form, twoor more tension tests (one from each end of each coil), and oneor more hardness tests shall be made on specimens taken fromeach end of the
37、coil. When material is supplied in flat sheet, flatstrip, or plate, one tension and one or more hardness tests shallbe made on each 100 or less sheets, strips, or plates of the samelot. When specified, one corrosion test shall be conducted foreach lot.12.2 If any specimens selected to represent any
38、lot fail tomeet any of the test requirements, the material represented bysuch specimens may be retested.
