Conduct of Examinations and Tests, Assistance, and Observers at an STF
All examinations and tests of the supplied-air suit by a DOE contractor should be under the
sole direction and control of the STF. Only personnel of the STF, the DOE contractor or his
designee, and such other persons as are requested by the STF may be present during any
examination and test of the supplied-air suit submitted by a DOE contractor.
General Criteria for Testing by STF
Each supplied-air suit submitted for evaluation of its performance should be examined and
tested in accordance with procedures set forth in this standard or equivalent procedure(s) in
a recognized standard such as EN-1073-1 (The European standard for ventilated protective
Initial Testing Criteria
11.1.1 The STF should not initiate testing unless the suit has been designed to allow
at least a 6.0 acfm flow of air to the helmet.
11.1.2 Written instructions covering donning, operation, maintenance, storage, and
contaminant protection offered should be provided along with the supplied-air suit to
the STF. The manufacturer's or the contractor's quality assurance program
pertaining to the supplied-air suit submitted by the DOE contractor should be
examined and studied by the STF staff. If these instructions or the assurance program
are considered inaccurate, confusing, or incomplete, the supplied-air suit should not
be considered acceptable for testing.
The supplied-air system should be equipped with an airflow meter or a pressure
gauge for measurement of the rate of flow of air to the supplied-air suit.
The entire supplied-air suit, including the breathing air hose and including
attachments, accessories, and auxiliary items (such as couplings, flow-control
valve, airflow meter, air-pressure regulator, air-pressure gauge, communications
equipment, gloves, boots, and shoe covers), submitted by the DOE contractor
should be used as appropriate during the testing process.
The test operator should examine the supplied-air suit worn by the suit tester to
observe if it contains any punctures, tears, seam separations, loose joints, and
other defects. If any such defects are found, the suit should not be considered
acceptable. This examination should also be carried out on a laundered or
reusable supplied-air suit or component if applicable.
Reusable or Laundered Supplied-Air Suit Components
If a supplied-air suit or a supplied-air suit component that has been reused or laundered is
submitted to the STF for testing, the maximum number of acceptable launderings or reuses
of the supplied-air suit or portion should be recorded and listed in the report containing the
