For each fuse found inoperable during these functional tests, an additional representative sample of at least 10K of all fuses of that type shall be functionally tested until no more failures are found or all fuses of that type have been functionally tested, or b.

By replacing 100K of all required fuses.

Functionally testing each overcurrent relay listed in Table 3.8.4. 1-1.

Testing of these relays shall consist of injecting a current in excess of 120K of the nominal relay initiation current and measuring the response time.

The measured response time shall be within +10K of the specified value.
