Requirement Conformance Criteria Requirement Paragraph

Verification Method Sample Acc Rej

1/ If no accept/reject criteria is expressed, the design represented by the sample or item lot shall be rejected if the items fail to comply with the applicable requirement.

2/ Estimated number for full verification test. This total includes 2% of additional items for risk mitigation (misfires, lost data, repeating firing events, etc.). Refer to contract for updated numbers.

3/ Sample size shall be sufficient to calculate for reliability at 91% and .80 LCB level for each firing modes. Recommend 60 items minimum (3 failures allowed). Leverage all applicable firing tests (accuracy, range, BOP, target effect) for reliability calculation.

4/ Sample size shall be sufficient to calculate for minimum and maximum range.

5/ Sample size is 10 minimum to determine probability of hits. Leverage all applicable firing tests if possible.

6/ All eligible dynamic firing events with high-speed camera/radar data shall be used to verify this requirement.

7/ Minimum of 60 for sample size. (See 6.2.ee) 8/ Document review by the U.S. Department of Transportation.

9/ All tests…
