3.3.1 Nominal classes of RDX. RDX made in accordance with
the respective processes for producing the specific classes of
RDX, but is not inspected for granulation requirements, (e.g.
nominal class 1 RDX).
3.4 Process controls. The contractor shall submit a Process
Control document to the Government specifying the process
variables which are considered crucial for the production of RDX.
The Process Control Document shall be submitted 30 days prior to
commencement of production in accordance with 4.2.
3.5 Limitation on the use of recycled RDX. RDX covered by
this specification shall consist of virgin RDX (see 6.10.1) and
only recycled RDX (see 6.10.2) from the RDX acid removal process.
3.6 Workmanship. The manufacturer shall use procedures and
controls which assure that the RDX produced does not contain
foreign material such as dirt, rust, paint or metal chips, etc.,
and that the safety and reliability of the explosive are not
compromised. Compliance with this requirement shall be as
specified in 4.7.9.
3.7 Product certification. No RDX material whether produced
for military or commercial use may be represented as meeting the
requirements of this detail specification unless it complies with
all requirements contained in Section 3. The process control
document (see 3.4), test data for first article inspection (see
4.4) and conformance inspection (see 4.5) shall be submitted to
the Technical Agency (see 6.12) for evaluation, approval and
certification on compliance with MIL-DTL-398.
