Abstract:

The Model 3610 System consists primarily of a Model 3000 Mixed Gas Helmet used with a neckseal and a Model 3700 Back Pack Scrubber. The system was tested for sound levels and ventilation efficiency using specially built test manikins. It was tested for diver comfort in a series of 20 manned dives. Since many of the testing methods used were new, a discussion of the procedures used as well as the results obtained is presented. The sound levels existing in the helmet were found to be into the damage risk levels under many of the conditions tested, but not so far as to preclude use of the system provided that appropriate precautions are taken. The ventilation efficiency of the system was found to be generally adequate for diving in the depth range of 0 to 300 fsw provided the gas supply pressure is maintained at sufficient levels.
