Sec. 32.103  Schedule D--prototype tests for ice detection devices 
containing strontium-90.

    An applicant for a license pursuant to Sec. 32.61 shall conduct 
prototype tests on each of five prototype ice detection devices as 
follows:
    (a) Temperature-altitude test. The device shall be placed in a test 
chamber as it would be used in service. A temperature-altitude condition 
schedule shall be followed as outlined in Step 1 through Step 10 of 
Sec. 32.101(a).
    (b) Vibration tests. The device shall be subjected to vibration 
tests as set forth in Sec. 32.101(b).
    (c) Shock test. The device shall be subjected to shock test as set 
forth in Sec. 32.101(d).
    (d) Hermetic seal and waterproof test. On completion of all other 
tests prescribed by this section, the device shall be immersed in 30 
inches of water for 24 hours and shall show no visible evidence of 
physical contact between the water and the strontium-90. Absolute 
pressure of the air above the water shall then be reduced to 1 inch of 
mercury. Lowered pressure shall be maintained for 1 minute or until air 
bubbles cease to be given off by the water, whichever is the longer. 
Pressure shall then be increased to normal atmospheric pressure. Any 
visible evidence of physical contact between the water and the 
strontium-90 shall be considered leakage.
    (e) Observations. After each of the tests prescribed by this 
section, each device shall be examined for evidence of physical damage 
and for loss of strontium-90. Any evidence of leakage or damage to or 
failure of any device which could affect containment of the strontium-90 
shall be cause for rejection of the design if the damage or failure is 
attributable to a design defect. Loss of strontium-90 from each tested 
device shall be measured by wiping with filter paper an area of at least 
100 square centimeters on the outside surface of the device, or by 
wiping the entire surface area if it is less than 100 square 
centimeters. The amount of strontium-90 in the water used in the 
hermetic seal and waterproof test prescribed in paragraph (d) of this 
section shall also be measured. The detection on the filter paper of 
more than 2,200 disintegrations per minute of strontium-90 per 100 
square centimeters of surface wiped or in the water of more than 0.1 
percent of the original amount of strontium-90 in any device, shall be 
cause for rejection of the tested device.
