(a) The contracting officer shall insert the clause at 52.246-7, Inspection of Research and Development—Fixed-Price, in solicitations and contracts for research and development when (1) the primary objective of the contract is the delivery of end items other than designs, drawings, or reports, (2) a fixed-price contract is contemplated, and (3) the contract amount is expected to exceed the simplified acquisition threshold; unless use of the clause is impractical and the clause prescribed in 46.309 is considered to be more appropriate.
