The test shall be reinitiated from the point of interruption using the same test item. I-4.2 ~& Any interruption in the’test that results in a more extreme exposure ,ofthe teat item than required by the equipment specification should be followed by a complete physical inspection of the test -itemand an operational check prior to continuation of test.
An engineering judgment ehall be mqde whether to continue testing with the specific item given the overtest, to obtain a new item, or to consider the teat completed. I-4.3 ~lure ~. All failures (see I-4.4) and incidents where the test items do not meet the equipment operating requirements shall be ana~yzed to determine the cause and impact-of such occurrences. Correctiveactions shall be proposed or implemented as required to meet equipment performance requirements. I-4.4 l?ailurecr&2c&. a.
