4.4.1 Torque test of insert. The body of the body assembly shall be held in place on a fixture and the torque shall be applied to the internal threads of the insert in accordance with the force specified on Drawing 13068386. If all assemblies meet the applicable requirement, the twenty (20) quantity of production represented by the sample shall be acceptable. If two (2) of the twenty assemblies fail to meet the applicable requirement, the quantity of production represented by the sample shall be rejected. If one (1) of the twenty assemblies fails to meet the specified requirement, an additional assemblies shall be subjected to this test. If one or more of these second twenty fail to meet the applicable requirement, the quantity of production represented by the sample shall be rejected. Samples successfully passing or not subjected to testing may be returned to the lot (Non-Destructive).

4.4.2 Cap push out force. After welding the cap shall be pushed out of the grenade body assembly at a velocity not to exceed 20±1 inches per minute until the cap has been completely dislodged. The direction of travel shall be along the thread axis. The peak force required to dislodge the cap shall be measured. If all assemblies meet the applicable requirement, the twenty

(20) quantity of production represented by the sample shall be acceptable. If two (2) of the twenty assemblies fail to meet the applicable requirement, the quantity of production represented by the sample shall be rejected. If one (1) of the twenty assemblies fails to meet the specified requirement, an additional assemblies shall be subjected to this test. If one or more of these second twenty fail to meet the applicable requirement, the quantity of production represented by the sample shall be rejected. Parts tested shall not be returned to the lot.

4.4.3 Salt spray. A quantity of five parts from each production lot shall be used as salt fog test samples in lieu of test panel specimens. A 120 hour salt fog exposure in accordance with ASTM B117 shall be performed after all specified protective finishes have been applied in accordance with Drawings 13068386, and either a subsequent air cure for 168 hours, or a force cure (i.e. force cure conditions recommended by paint manufacturer). The samples shall be evaluated in accordance with paragraph 3.5.8 (Accelerated Corrosion Resistance) of TT-C-490.

This is a destructive test. Upon completion of testing, the test samples shall not be returned to the production lot.

4.4.4 Ammunition lot number. Visually verify that an ammunition lot number has been assigned to each lot as described in MIL-STD-1168.

5. PACKAGING

5.1 Packaging materials, components and assemblies. The materials, components, and assemblies shall be in accordance with all the requirements specified on Drawing 13059163.

6. NOTES

4.4 Test methods and procedures.

4.4.1 Torque test of insert. The body of the body assembly shall be held in place on a fixture and the torque shall be applied to the internal threads of the insert in accordance with the force specified on Drawing 13068386. If all assemblies meet the applicable requirement, the twenty (20) quantity of production represented by the sample shall be acceptable. If two (2) of the twenty assemblies fail to meet the applicable requirement, the quantity of production represented by the sample shall be rejected. If one (1) of the twenty assemblies fails to meet the specified requirement, an additional assemblies shall be subjected to this test. If one or more of these second twenty fail to meet the applicable requirement, the quantity of production represented by the sample shall be rejected. Samples successfully passing or not subjected to testing may be returned to the lot (Non-Destructive).

Cap push out force. After welding the cap shall be pushed out of the grenade body assembly at a velocity not to exceed 20±1 inches per minute until the cap has been completely dislodged. The direction of travel shall be along the thread axis. The peak force required to dislodge the cap shall be measured. If all assemblies meet the applicable requirement, the twenty (20) quantity of production represented by the sample shall be acceptable. If two (2) of the twenty assemblies fail to meet the applicable requirement, the quantity of production represented by the sample shall be rejected. If one (1) of the twenty assemblies fails to meet the specified requirement, an additional assemblies shall be subjected to this test. If one or more of these second twenty fail to meet the applicable requirement, the quantity of production represented by the sample shall be rejected.

Parts tested shall not be returned to the lot.

4.4.2 Salt spray. A quantity of five parts from each production lot shall be used as salt fog test samples in lieu of test panel specimens. A 120 hour salt fog exposure in accordance with ASTM B117 shall be performed after all specified protective finishes have been applied in accordance with Drawings 13068386, and either a subsequent air cure for 168 hours, or a force cure (i.e. force cure conditions recommended by paint manufacturer). The samples shall be evaluated in accordance with paragraph 3.5.8 (Accelerated Corrosion Resistance) of TT-C-490. This is a destructive test. Upon completion of testing, the test samples shall not be returned to the production lot.

4.4.3 Ammunition lot number. Visually verify that an ammunition lot number has been assigned to each lot as described in MIL-STD-1168.

5. PACKAGING

5.1 Packaging materials, components and assemblies. The materials, components, and assemblies shall be in accordance with all the requirements specified on Drawing 13059163.
