Pre-Rinse Spray Valves in Laboratories

I have several pre-rinse spray valves that were specified by an external laboratory consultant in a college laboratory building that do not appear to meet the requirement of being less than or equal to 1.6 gpm. There seems to be a slight discrepancy between the online form and the physical reference guide. In the reference guide, it states "Commercial pre-rinse spray valves (for food service applications)", but the online form says all pre-rinse spray valves. The pre-rinse spray valves would not be used for food service applications, so we are trying to decide if we need to make the external lab consultant re-specify pre-rinse spray valves that meet the requirement of 1.6 gpm. Thoughts/interpretations?
