Note 1) To be performed using a defined sampling procedure for inspection determined by the mortar cartridge lot sizes.

4.1.1 Lot formation. The mortar ammunition shall be assembled into identifiable lots, sublots, or batches, or in such other manner as may be prescribed. Each lot or batch shall, as far as practicable, consist of units of product of a single type, grade, class, size, and composition, manufactured under essentially the same conditions, and at essentially the same time. Lot quantity shall be determined by the total quantity for shipment and include the additional rounds from that same lot to be consumed during lot acceptance testing along with contingency rounds for potential re-testing. The lots or batches shall be identified by the contractor and shall be kept intact in adequate and suitable storage space. All cartridges in a given lot must be manufactured prior to lot acceptance testing.

4.1.2 Conformance verification. The mortar ammunition shall be subjected to verification in accordance with TABLE I of this specification.

4.1.3 Conformance acceptance. Acceptance of mortar ammunition shall be based on compliance with the requirements in TABLE I of this specification. Failure to meet requirements of

TABLE I shall be cause to withhold acceptance of lot or batch for which verification was performed.

A Request for Variance (RFV) may be submitted for special consideration of a lot that does not comply with all requirements of the TDP. The US Government may approve or disapprove the RFV on a case by case basis.

4.1.4 Retest criteria. A ballistic retest is authorized upon initial failure of mortar ammunition to meet test requirements as long as the failure is not considered critical. Retest procedures must be clearly defined in the TDP and results must be combined with data from the first test unless a failure analysis confirms that the failure was caused by something other than the ammunition (i.e. weapon failure or faulty test set up).

4.2 Verification of evidence of compliance. Evidence shall include, but is not limited to, the following;

a. Identification of technical requirements to which the mortar ammunition is/was produced.

b. Producer, date of manufacture and original acceptance documentation.

c. In-Process acceptance reports, including type, lot or batch identification, quantity and method of acceptance (e.g. sample size, verification method, acceptance criteria, results).

d. Surveillance reports, including lot or batch identification, quantity and method of surveillance (e.g. sample size, verification method, criteria for action to be taken on lot or batch, results).

e. Storage history, including duration and storage condition (e.g. controlled, uncontrolled).

4.3 Serviceability and identification of defects. A random sample shall be selected from each lot of mortar ammunition using a defined sampling procedure for inspection. The ammunition shall be visually inspected for signs of degradation and the identification of defects i n accordance to

ANNEX C of this specification. Re-inspection of a lot that fails for non-ballistic reasons is authorized as long as the criteria for re-inspection is clearly outlined in the TDP per ANNEX C.

4.4 Weapon interface and interoperability. A random sample shall be selected from each lot of mortar ammunition to be delivered and inserted into a weapon chamber or chamber gage that conforms to the identified weapon system to check for profile and alignment. Inability to interface properly with weapon system shall be considered a failure to show compliance and constitute a single reliability failure.

4.5 Operating verification. The same cartridge of mortar ammunition can be used for multiple tests provided the test equipment is capable of capturing all necessary test data. For example; Muzzle

Velocity, Maximum Effective Range and Function & Causality testing can be done at the same time using the same mortar cartridge. Called warmers and spotters are allowed and encouraged. "Called" means that before the mortar cartridge is loaded into the weapon, the US Government representative must be informed that the next mortar cartridge to be fired is a warmer or spotter. Should a mortar cartridge not be "Called" it shall be counted toward whichever test is being conducted, potentially resulting in a LAT failure. Safety failures apply to all cartridges fired during LAT, regardless of which test is being performed. The following safety failures shall result in the immediate rejection of the lot;

there shall be no retest:

a. Detonation of an HE, Practice or Smoke cartridge within the weapon or before impact with the ground.

b. Any in-bore or early functions of the fuze (Illumination cartridge)

c. Metal parts separation.

d. Short rounds; a cartridge impacts the ground at a range 80% or less of the range average or its respective temperature/charge/group; excluding the cartridge(s) in question.

e. A cartridge that either causes injury to user, damages the weapon or renders it inoperable

(without the use of special tools).

4.5.1 Operating temperatures. Mortar ammunition shall operate reliably and safely when conditioned and fired throughout reasonable extreme operating temperature range as provided by the manufacturer. Temperature testing may be conducted on a skip-lot basis (see APPENDIX) during

LAT. A single safety failure will result in lot rejection and there shall be no retest. Functional testing parameters must be defined in the technical data and meet manufacturer requirements. The entire mortar cartridge, including all components necessary to fire and function (i.e.: fuze, warhead, propellant, etc.) shall be temperature conditioned based on the maximum mortar cartridge body diameter. Additionally the mortar cartridges shall be fired within the following times after being removed from the conditioning chamber or thermally insulated bag.

a. Ammunition less than 85mm in diameter shall be conditioned for not less than six (6) hours and fired within five (5) minutes of removal from conditioning box or thermally insulated bag.

b. Ammunition between 85mm and 120mm in diameter shall be conditioned for not less than nine (9) hours and fired within six (6) minutes of removal from conditioning box or thermally insulated bag.

c. Ammunition greater than 120mm in diameter shall be conditioned for not less than twelve

(12) hours and fired within eight (8) minutes of removal from conditioning box or thermally insulated bag.

4.5.2 Muzzle Velocity. Velocity tests shall be conducted in accordance with the manufacturers test procedures to verify that a sample representative of the lot meets the minimum velocity requirements specified in ANNEX B. If the lot fails to meet the Velocity requirements a retest of the same sample size (10 cartridges minimum) is permitted. The cumulative average of all mortar cartridges tested (20 cartridges minimum) shall be used to determine if the lot passes.

4.5.3 Chamber Pressure. Pressure tests shall be conducted in accordance with the manufacturers test procedures to verify samples from the lot do not exceed the average or individual pressure requirements listed in ANNEX B. Pressure testing shall be conducted during the LAT, regardless of in-process testing. If the lot fails to meet the Pressure requirements a retest of the same sample size (10 cartridges minimum) is permitted. The cumulative average of all cartridges tested (20 cartridges minimum) shall be used to determine if the lot passes. Any single round that exceeds the maximum individual pressure requirement will result in lot rejection, there shall be no retest.

4.5.4 Maximum Effective Range. Maximum effective range shall be verified during lot acceptance testing to ensure compliance with ANNEX B.

4.5.5 Dispersion. Dispersion tests shall be conducted to verify that each lot of ammunition meets the specified requirements in the TDP. If the lot fails to meet the Dispersion requirements a retest of the same sample size (10 cartridges minimum) is permitted. The cumulative average of all cartridges tested (20 cartridges minimum) shall be used to determine if the lot passes.

4.5.6 Function and casualty. A random sample shall be selected from the ammunition lot in accordance to ANNEX A to be delivered and functioned from the identified weapon system to check for function, casualty and metal parts security. The ammunition shall function across the entire operating temperature range (extreme hot, cold, ambient) without casualty or damage to the weapon, and shall exhibit a ballistic performance free of misfires, duds, premature bursts, short rounds and metal parts separation. The ammunition shall cause no hazard or unsafe condition to the gunner during storage, transportation or use. Any rounds which detonates prior to impact of intended target, or which detonates in the weapon is considered a safety critical failure and will result in immediate lot rejection. Multi-option fuzes shall be set to Point Detonating for LAT testing.

4.5.7 Performance. Proper functioning for each mortar ammunition type is defined below.

Any round which does not function properly according to the requirements of the producer’s test procedures and the below definitions is considered a function failure.

a. HE Fragmentation: The ammunition shall produce a high-order detonation of the warhead upon initial impact with the target as specified in the TDP.

b. Smoke: The ammunition shall produce a volume of smoke upon impact with the target as specified by the manufacturer in the TDP.

c. Illumination: The ammunition shall provide candlepower illumination and parachute suspended burn time as identified in the TDP.
