4.4.2 Test routine. Sample units will be subjected to the qualification inspection specified in table V in
the order shown. All sample will be subjected to the inspection of group I. The 60 sample units of 5
percent resistance tolerance will then be divided as specified in table V for groups II to V, inclusive and
subjected to the inspection for their particular group. When applicable 10 additional sample units will be
submitted to the inspection of group VI. When approval for a lower resistance tolerance is desired, 20
additional sample units will be submitted to the inspection of group I.
4.4.3 Failures. Failures in excess of those allowed in table V shall be cause for refusal to grant
qualification.
