3.6.1 .2.5 On board repair parts list.  A list of on board repair parts
shall accompany the outline drawings.  This list shall be prepared on provision-
ing list forms in accordance with MIL-P-15137.  This list shall be furnished
whether or not the parts are required in the pump contract or order,  This list
shall not be modified to indicate parts or quantities of parts furnished under
supplementary or separate contracts or orders.  The list is intended as a record
of recommendations of the manufacturer and purchaser at the time of equipment
drawing approval.  The list of on board repair parts actually purchased shall be
prepared as required by MIL-P-15137 (see 6.5.2).
3.6. 1.2.6 Review.  Design drawings shall be submitted to the design review
agency for approval (see 6.2.1).

this specification are intended for submittal to the design review agency prior
to and independent of invitations for bids.  As such these are different from
design drawings as described in 3.6.1.2.  Each drawing may be a range of sizes
of pumps so long as they are of the same basic design.
3.6.1 .3.1 Contents of basic design drawings.  These drawings shall consist
of small scale (not necessarily to scale) plan and elevation views showing over-
all dimensions.  If the plans cover a family of pump sizes all of the same
design, the dimensions may be tabulated.  The range of capacities, pressure and
speeds shall be shown.  The main part of this drawing shall be an undimensioned
sectional assembly with complete list of material which shall include every part
required in the pump assembly.  If materials of some parts may change with
various pump characteristics or with differing fluids to be pumped, a table shall
be included to show these variations.  Alternate subassembly arrangements of
different parts may be included as desired.
3.6.1 .3.2 Detail drawings of individual parts are not required in
connection with basic design drawings, but may be included if desired by the
manufacturer for clarification, or to obtain advance approval of the design
review agency.
3.6.1.4 On one of the delivered design drawings described in 3.6.1.2, the
mechanical seal contractor shall identify and certify the following:
(a) Whether or not there is an adhesive or other setting compound
