This response is based on the information provided.  We suggest you discuss with your contracting team, program manager and/or legal department as appropriate.

Assuming a properly formed contract, this effort is at or below the simplified acquisition threshold given the quality clause in the contract.  The contractor is ISO9000:2015/AS9100 certified.  As to your question, "...to ensure that manufacturing or quality requirements are adequately stated?"; stating what the quality requirements are is a function of the government in its RFP/solicitation and ensuing contract.  Since FAR 52.246-1 is in the contract we assume the contracting officer has not made the determination specified in FAR 46.202-2 (b).  You can check the CDRL list to see if any deliverables would allow some minimal review.
