Gas Testing of Equipment to be Used in Alvin?s Personnel Sphere
The U.S. Naval Sea Systems Command (NAVSEA), Alvin’s
certifying agency, requires the testing of all scientific instrumentation
brought into the personnel sphere for toxicity and flammability.
The testing consists of 24
hours of operation in an isolated chamber at 100degF to measure
offgassing, followed by a
15-minute, power-on bench segment to record maximum component
temperatures. The tests are performed at WHOI some period of
time (usually 30 days) prior to cruise departure, and gas samples
are sent to a chemical lab for analysis. Items are tagged following
testing, and a list of tested material is maintained at WHOI
so that repeated tests of unmodified instruments will not be
Remember: if your gear is not tested, the Operations Group on board Atlantis will not allow it to be taken into the sphere. Any questions about this procedure should be directed to Rick Chandler at WHOI.
