If a problem is discovered, the preferable aourse of action is to terminate the test and reinitiate testing with a new test item. If this is not done and test item failure occurs during the remainder of the teat, the test results could be considered invalid becauee of the overtest condition, If no problem has been encountered, reestablish preinterruption conditions and continue from the point where the test tolerances were exceeded. 11-2 &wmuQum 11-2.1 &reliminarv s-.

The following test procedures, alone or in combination, provide the bases for collecting the necessary information concerning the test item in a cold environment. Operational checkouts should be conducted after ~. storage and after manipulation to verify successful completion of both procedures.
