TO BE RESCINDED

 

3701:1-46-47               Prototype       tests     for     ice      detection     devices                      containing strontium-90.

 

 

An applicant for a license pursuant to rule 3701:1-46-40 of the Administrative Code shall conduct prototype tests on each of five prototype ice detection devices as follows:

Prototype tests

 

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 one through step ten of Table 1 in rule 3701:1-46-45 of the Administrative Code.
Vibration tests	The device shall be subjected to vibration tests as set forth in paragraph (B) of rule 3701:1-46-45 of the Administrative Code.
Shock test	The device shall be subjected to shock test as set forth in paragraph (D) of rule 3701:1-46-45 of the Administrative Code.
Hermetic seal and waterproof test	On completion of all other tests prescribed by this rule, the device shall be immersed in thirty inches of water for twenty-four 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 one inch of mercury. Lowered pressure shall be maintained for one 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.
Observations	After each of the tests prescribed by this rule, 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 one hundred square centimeters on the outside surface of the device, or by wiping the entire surface area if it is less than one hundred square centimeters. The amount of strontium-90 in the water used in the hermetic seal and waterproof test prescribed in this table shall also be measured. The detection on the filter paper of more than two thousand two hundred disintegrations per minute of strontium-90 per one hundred square centimeters of surface wiped or in the water of more than 0.1 per cent of the original amount of strontium-90 in any device, shall be cause for
