3.2 Conformance. A sample shall be subject to conformance inspection in accordance

with 4.5. Analytical results shall be IAW MIL-STD-1171 (see 6.2).

3.3 Materials.

3.3.1 Alcohol. The alcohol used in the manufacture of alcohol wet nitrocellulose shall

conform to the requirements for Grade 2 of A-A-59342.

3.3.2 Cellulose. The cellulose used shall be derived from cotton cellulose, woodpulp

cellulose obtained by the sulfate process, or woodpulp cellulose obtained by the sulfite

process, conforming to the requirements of MIL-C-206, MIL-C-20330, or MIL-C-216

respectively (see 6.14).

3.4 Nitrocellulose.

3.4.1 Nitrogen content and blending allowance. The nitrocellulose shall meet the

nitrogen content requirement for the required grade and type specified in Table I. Blending

may be used to achieve the applicable requirements for each particular grade in accordance

with the range specified in Table I. Blending allowance is defined as the required nitrogen

content obtained by blending nitrocellulose containing the percent nitrogen in the range

listed. Unless otherwise specified, Grade C blends shall be manufactured with Grade B Type

I and Grade A Type II. For certain Grade C blend applications, Grade B Type II or Grade F

nitrocellulose components may be used when specified in the contract or order.

NOTES:

Class 1 – Combustible cartridge applications. The nitrocellulose shall be of either Grade A or Grade B and

shall meet the nitrogen content in Table I for the grade/type specified in the contract or purchase order.

Class 2 – Solvent and solventless propellant applications. The nitrocellulose shall meet the nitrogen

content in Table I for the grade/type specified in the contract or purchase order.

Class 3 – Propellants made from lacquer applications. Lacquer applications are propellant products that

are made with completely solvated nitrocellulose from a homogenous mixture of nitrocellulose, stabilizer

and solvent. The nitrocellulose shall be Grade C and shall meet the nitrogen content in Table 1 for the

grade/type specified in the contract or purchase order. It is permissible that during the lacquer

manufacturing process, nitrocellulose with a nitrogen content of 12.4% or greater may be used as long as

the final nitrogen meets the nitrogen requirements of Grade C nitrocellulose. Any nitrocellulose used with

a nitrogen content below 12.75% shall be subject to the chemical requirements (other than nitrogen

content) of Grade A nitrocellulose. Any nitrocellulose used with a nitrogen content above 12.75% shall be

subject to the chemical requirements (other than nitrogen content) for Grade B nitrocellulose.
