If you look at an audit check-list you may find your answer. I looked and found several questions related to acceptance criteria. Google ISO 13485 7.1q3 audit checklist. i.e.
In planning product realization, the organization shall determine the following, as appropriate:
a) quality objectives and requirements for the product;
b) the need to establish processes, documents, and provide resources specific to the product;
c) required verification, validation, monitoring, inspection and test activities specific to the product and the
criteria for product acceptance;
d) records needed to provide evidence that the realization processes and resulting product meet requirements (see 4.2.4).
Not sure if this helps but if it does...I'm happy to have helped
