5. PACKAGING

5.1 General. The packaging requirements shall be as specified in the contract.

6. NOTES

6.1 Definitions. For the purpose of this PD, the following definitions apply.

6.1.1 Thresholds and Objectives. A threshold is defined as the minimum acceptable value below which the utility of the system becomes unacceptable. An objective is defined as the desired operational goal associated with a performance attribute, beyond which any gain in utility does not warrant additional expenditure. The objective value is an operationally significant increment above the threshold. An objective value may be the same as the threshold when an operationally significant increment above the threshold is not useful. An objective is not considered to be achieved unless the threshold is also achieved (except for when the threshold and objective are mutually exclusive).

6.1.2 Failure. A failure is any of the following.

a. A stoppage in weapon function not caused by trigger manipulation.

b. A failure to stop firing when the trigger is released.

c. A malfunction where the weapon does not operate in accordance with design intent.

d. The occurrence of a broken or unserviceable part that renders the weapon inoperable or unsafe if firing is continued.

6.1.2.1 Failure Classifications.

Class I: A failure that may be immediately corrected by the operator within 10 seconds or less while following prescribed immediate action procedures.

Class II: A failure that may be corrected by the operator, and that requires more than 10 seconds but not more than 10 minutes to correct (less the TM/OM defined cool down period if a hot barrel condition exists). Only the equipment and tools issued with the weapon may be used to correct the failure.

Class III: A failure of a severe nature. The failure (1) can be corrected by an operator but requires more than 10 minutes, (2) cannot be corrected by an operator and requires assistance (no time limit), or (3) requires a higher level of maintenance, or correction by an authorized operator cannot be accomplished because of unavailability of necessary tools, equipment or parts.

6.1.3 Fighting Load. The fighting load is defined as helmet (with band and cover), leather black gloves (with inserts), Modular Tactical Vest (with attached throat protector and collar), body armor plates inserted in the outer tactical vest (front and back), twelve 40mm grenades, 1 utility/canteen pouch, 1 Individual First Aid Kit (IFAK), 1 patrol pack, 1 bayonet (with scabbard), 1 set of camouflage paint, 1 pair of sand/wind/dust goggles, 1 set of earplugs, 1 Meal Ready to Eat (MRE), 1-100 Oz. “CamelBak” Hydration System (filled), 1 M40 gas mask (with canister inserted, carrier and waterproof bag), 1 watch, 1 camouflage uniform, 1ID card, and 1 set of dog tags. The approximate weight of the fighting load is 75 lbs.

6.1.4 Reliably Function. This term indicates that the weapon functions with no apparent degradation of reliability. Usually this phrase is applied when full reliability testing will not be completed to verify reliability to a specific confidence level. However, significant increases in the number of failures during individual tests will be noted and may be further investigated.

6.1.5 Degradation of Performance. Degradation of performance is defined as a change in the measured level of performance to a value that is greater than 120% or less than 80% of the original performance, or a change that results in a measured level of performance less than the minimum performance required by this PD.

6.1.6 Safely Function. To safely function indicates that the weapon continues to function properly and that no events occur that would cause doubt as to whether the weapon is safe for use.

6.1.7 Significant Safety Risk. A significant safety risk is any hazard that is classified as “High” or “Serious” as stated in MIL-STD-882D.

6.1.8 Ready to Fire. A weapon that is ready to fire requires nothing to advance and fire the next round except pulling the trigger.

6.1.9 40mm Low Velocity Ammunition. 40mm x 46mm standard DODIC ammunition.
