MIL-DTL-48568D(OS)
4.3.4 Propellant morphology. Two sleeve and grain assemblies from each batch of propellant used in the
first article sample shall be submitted for morphological examination to the Indian Head Division, Naval
Surface Warfare Center, Indian Head, MD 20640-5000, Attn: Code 5120. All samples shall be individually
wrapped in moistureproof packaging and properly identified as to propellant lot, batch number, and grain
serial number. These tests shall be used as the baseline information.
4.4 Quality conformance inspection. Quality conformance inspection shall consist of the examinations and
tests of 4.4.4 through 4.4.6, conducted on samples selected as specified in 4.4.2. The contractor is responsible
for assuring that all rocket catapults offered for acceptance meet all requirements of the applicable drawings
and specifications. Items of inspection shall be serialized and inspection data traceable to a specific serial
number.
4.4.1 Test reports. When specified in the contract or order (see 6.2), the contractor shall furnish test reports
to the contracting activity. Test reports shall include the following information as described in 4.4.1.1 through
4.4.1.6:
a.
Propellant description (see 3.2.2)
b.
Static firing performance test results (see 4.4.5.1)
c.
Summary sheet
d.
Ammunition data cards
e.
Propellant/assembly production records
f.
Certification of age of explosive components and propellant (see 3.3)
4.4.1.1 Propellant description. The following propellant information shall be submitted with each
production lot. The materials and components of each propellant batch shall be listed along with the
manufacturer, lot number, and date of manufacture. The burning rates at 1000, 2000, 3000, 4000, and 5000
psi performed at 65, 70, and 165 F for each pressure (three samples at each temperature and pressure per
batch) for the cartridge grain and at 1500, 2000, 2500, 3000, 4000, and 5000 psi performed at 65, 70, and
165 F for each pressure (three samples at each temperature and pressure per batch) for the rocket motor
grain shall also be included. In addition, include the results of tensile strength and elongation tests at 65, 70,
and 165 F with a pull rate of 2 inches/minute (five samples at each temperature per batch), heat of explosion
(three samples per batch), and verification that ingredients were properly weighed and added to each batch
(mix sheet).
4.4.1.2 Static firing performance tests. All computations and data required for ballistic evaluation
generated during quality conformance inspection static firing per 4.4.5 (Government) and 4.4.5.1 (contractor)
shall be reported, including firing traces. The following information shall also be listed:
a.
Grain designation, manufacturer, lot number, and date of manufacture
b.
Type of test equipment
c.
Deviations from standard testing procedures
d.
Additional comments (malfunctions, unusual occurrences)
e.
Disassembly findings report (see 4.4.5.2)
4.4.1.3 Summary sheet. A summary of the results of the inspections required by 3.5 through 3.12 shall be
submitted to the designation Government activity for each inspection lot. The summary shall include the
sample size, number and nature of defects found, and the disposition (accepted or rejected).
