4.4.1 Samples for qualification. Samples submitted for qualification approval shall be representative
of the contractor s normal production and shall be taken, preferably, from a current production lot. Ten
specimens of each type for which approval is requested shall be submitted for qualification approval.
However, when a contractor s design for a particular type is basically the same in various current or
voltage ratings, one set of specimens may be submitted for approval of that design. For this case,
approval shall be extended to all units submitted by the same contractor of the same design of lower
current or voltage rating. Qualification approval of a type listed in column I of table II shall be extended to
the type shown opposite in column II except for visual and mechanical examination and the tests listed in
column III. Two samples of each fuseholder listed in column II shall be submitted for visual and
mechanical examination. Samples for tests listed in column III shall be tested as specified in the
applicable group in table I.
