An interruption that results in less severe conditions than specified should be ‘treatedas a test.” The test item should be dried and stabilized at standard ambient conditions and the entire test procedure repeated.from the beginning. Any failure discovered during an undertest condition should be treated as a failure. b. S@2rtest interruDtisina. Any interruption that results in more severe conditions than specified should be followed by a complete examination of the test item and an operational check (where possible) before continuation of testing. If no problem is evident, the test should be restarted, preferably with a new test item.. 11-2.1 ~.
Before initiating any testing, determine from the test plan: = a. The immersion depth and time and, if applicable, the Dreheat temperature and duration. :t@THOD.512.2 19 JuIY’;,1983 512.2-6
