3.1.2 Analysis shall be made routinely only for the elements specifically
mentioned in table I. If, however, the presence of other elements is
suspected, or indicated in amounts greater than the specified limits further
analysis shall be made to determine that the total of other elements is not in
excess of these limits.
3.1.2.1 The contractor shall furnish analysis of each melt showing the
percentage of each of the elements designated in table I.
3.1.2.2 Chemical analysis by the contractor of the individual melts may be
waived at the discretion of the procuring activity provided that the
producer's method of the composition control is acceptable or that all
material in the lot can be identified as being from melts previously analyzed
and found to be in conformance with the chemical composition requirements.
3.2 Mechanical properties. The mechanical properties of nickel bar,
flat wire (ribbon) and strip shall be in accordance with the requirements
specified in tables II and III.
