FIGURE 1 Flow test jig.

4.6.5.2 First article hardness test. Curing conditions and hardness values for

first article testing shall be as specified in table I for conditions l and 2.

4.6.5.3 Quality conformance hardness test. Curing conditions and hardness

value for quality conformance testing shall be as specified in table I for condition 3.

4.6.6 Low temperature stability. Two room-temperaure test panels shall be

placed in a temperature chamber for low temperature stability testing. The

temperature shall be lowered to -54� � 3�C at a rate of 10 per minute. The test panels

shall remain at this temperature for not less than 1 hour, after which they shall be

examined. There shall be no evidence of cracking, checking, or loss of adhesion.
