Sec. 32.40  Schedule A--Prototype tests for automobile lock illuminators.

    An applicant for a license pursuant to Sec. 32.14 to install lock 
illuminators into automobile locks, or to initially transfer lock 
illuminators in automobile locks for use pursuant to Sec. 30.15 of this 
chapter shall conduct the following prototype tests on each of five 
prototype devices, consisting of the automobile lock with the installed 
illuminator in the following order:
    (a) The device shall be subjected to 100 hours of accelerated 
weathering in a suitable weathering machine which simulates the most 
severe conditions of normal use;
    (b) The device shall be dropped upon a concrete or iron surface in a 
3-foot free gravitational fall, or shall be subjected to an equivalent 
treatment in a test device simulating such a fall. The drop test shall 
be repeated 100 times from random orientations;
    (c) The device shall be attached to a vibratory fixture and vibrated 
at a rate of not less than 26 cycles per second and a vibration 
acceleration of not less than 2 G for a period of not less than 1 hour;
    (d) On completion of the foregoing tests, the device shall be 
immersed in 30 inches of water for 24 hours and shall show no visible 
evidence of water entry into the lock illuminator. 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 evidence of 
bubbles emanating from within the lock illuminator, or water entering 
the lock illuminator, shall be considered leakage;
    (e) After each of the tests prescribed by this section, each device 
shall be examined for evidence of physical damage and for loss of 
tritium or promethium-147. Any evidence of damage to or failure of any 
device which could

affect the containment of the tritium or promethium-147 in such devices 
shall be cause for rejection of the design on which such prototype 
devices were constructed or manufactured if the damage or failure is 
attributable to design defect. Loss of tritium or promethium-147 from 
each tested device shall be measured both by sampling the immersion test 
water used in paragraph (d) of this section and by wiping with filter 
paper the entire accessible area of the lock illuminator. Measurements 
of tritium or promethium-147 shall be made in an apparatus calibrated to 
measure tritium or promethium-147, as appropriate. If more than 0.1 
percent of the original amount of tritium or promethium-147 in the 
device is found in the immersion test water of the test in paragraph (d) 
of this section, or if more than 2,200 disintegrations per minute of 
tritium or promethium-147 on the filter paper is measured after any of 
the tests in paragraphs (a) to (d) of this section the device shall be 
rejected.
