The provided text does not contain information about acceptance criteria or a study proving that the device meets those criteria. The document is a 510(k) summary for a dental core build-up composite called "Light-Core™", outlining its characteristics and comparing it to a predicate device. It includes the intended use, chemical composition, physical/mechanical properties, biocompatibility, depth of cure, physical description, and handling time. However, it does not specify any quantitative acceptance criteria or a study's results against such criteria.

Therefore, I cannot provide the requested information.
