Normally, testing and approval is not required in contracts for -
(a) Research or development;
(b) Products requiring qualification before award (e.g., when an applicable qualified products list exists (see Subpart 9.2));
(c) Products normally sold in the commercial market; or
(d) Products covered by complete and detailed technical specifications, unless the requirements are so novel or exacting that it is questionable whether the products would meet the requirements without testing and approval.
