The voluntary consensus standard, ANSI/ISEA Z358.1-2009, American National Standard for Emergency Eyewash and Shower Equipment is currently under revision and is expected to be published as a revised document in 2014. 

This globally-accepted standard is the authoritative document that specifies minimum equipment performance criteria for flow rates, temperature delivery and drenching patterns—all characteristics that are important for a user to receive adequate rinsing of a contaminant from the eyes, face and body in an emergency situation.
