The Navy Experimental Diving Unit NEDU is the United States Navy facility for testing and evaluating underwater breathing apparatus UBAs. Each military or commercial UBA that the Navy considers for use is sent to NEDU for an in-depth evaluation of its performance, material suitability, human factors, and systemic reliability. This technical manual supersedes NEDU TM 01-94 and presents the unmanned performance goals and test methods NEDU currently uses to evaluate UBAs. This manual employs physiologically-based performance goals and limits- a significant departure from previous engineering-based goals. Much of the rational for this transition is detailed in NEDU TR 15-03 and various publications cited in this manual. The instrumentation and test methods described in this manual should allow any hyperbaric test facility to reproduce the tests conducted by NEDU. Any test instrument comparable to those specified in the UBA test setup may be used, if its accuracy and response characteristics are equal to or exceed those used by NEDU- and if its calibration is traceable to National Institute of Science and Technology standards.
