4. 8.1.3.4.2 Post humidity operation. At the completion of the
five humidity cycles, the FCC-FTS shall be removed from the humidity
chamber and subjected to the post operational performance tests in
accordance with paragraph 4S6.2 of this procedure as soon as
possible, but not later than one hour after completion of the
humidity test. Prior to measurements, excess moisture may be
removed frm the exterior surfaces of the FCC-FTS by turning the
unit upside down or by wiping the external surfaces only. Record
the results of this test on the applicable data sheet.
4. 8.1.3.4.3 Moisture test. Following the above check for
satisfactory operation the FCC-FTS shall be opened and examined for
evidence of entrapped moisture. Record the results of this
examination on the applicable data sheet.
