Notes:
1/ A cup-insulator button assembly which fails to comply with the insulation strength requirement shall
be rejected.
2/ A primer which fails to comply with the applicable electrical resistance requirement shall be rejected.
3/ A primer which fails to comply with the applicable minimum dry weight requirement shall be rejected.
4/ If the average firing voltage (V) plus three standard deviations (3σ) exceeds 160 volts, the lot shall be
rejected or the first article sample will fail. For conformance inspection, the lot shall be subject to retest.
If on retest, V + 3σ exceeds 160 volts the lot shall be rejected. If in either the first test or the retest, a
primer fails to fire at 160 volts, the lot shall be rejected (see 6.8).
5/ If the sample average primer time plus four standard deviations exceeds 300 microseconds or if an
individual primer time of the test sample exceeds 300 microseconds, the lot shall be rejected or the first
article sample will fail (see 6.8).
6/ If the sample average action time plus four standard deviations exceeds 3.5 milliseconds, or an
individual primer action time of the test sample exceeds 3.5 milliseconds, the lot shall be rejected or the
first article sample will fail (see 6.8).
