For partial qualification, testing to one particular inductance value shall be sufficient to gr
9、ant qualification approval to any smaller inductance value than what was qualified. 2/ The inductance is measured with 0 A dc applied to (1-2) and at the specified test voltage across (1-2). 3/ The amount of dc current that will reduce the inductance a maximum of 8 percent.
