Evaluations were conducted on Performance Inc, Chapel Hill, NC, PDXL 700 and PDXL 1000 regulators, to determine which commercially available open- circuit SCUBA regulators were capable of meeting performance goal standards for Navy use. Bench testing of all candidate regulators was conducted to establish flow patterns and air delivery capacity. Unmanned testing using a breathing simulator at ventilation rates of 22.5, 40, 62.5, and 90 Lmin at test depths of 0 to 60 msw 0 to 198 fsw, in 10 msw 33 fsw increments was conducted to determine work of breathing WOB values. Each candidate regulator model was subjected to five runs each and a mean of the WOB was established. This mean WOB value was then compared to the Performance Goal Standard of 1.37 Joules per liter JL at 60 msw 198 fsw. Testing was conducted in ambient temperature water, approximately 21 dec C 70 deg F, with a supply pressure of 10.34 MPa 1500 psi. All testing conducted determined that none of the candidate test regulators were capable of meeting the requirements for acceptance by the US navy.
