Qualification of wire:
For qualification, a source is required to submit data on quality conformance tests and any finished wire tests as
required by the qualification authorization letter. All other testing will be performed by the qualifying activity at the
source's expense.
Due to the extended time period over which the thermal index test is performed, a source may become qualified under
this specification sheet while this test is still in progress.
