Book Description
In June 1979 the Navy Experimental Diving Unit performed unmanned tests on 36 open circuit scuba regulators currently manufactured in the United States. Breathing resistance, respiratory work and first stage performance were evaluated. Results of these tests produced a new NEDU scuba regulator performance requirement to replace the current requirement taken from Mil-R-24169A. Of the 36 regulators tested, 7 regulators met the upgraded performance standard, 22 regulators and one full face mask met Mil-R-24169A, and 6 regulators did not meet Mil-R-24169A. (Author).
