MIL-P-64036(AR)
3.5.1 Adapter.  Minimum mechanical properties as required by
the applicable drawing may apply to specimens machined from the raw
material, provided that the mechanical properties are not altered
during manufacture.
3.6 Metal defects.
3.6.1 Body.  The body, including the cavity, shall be free from
cracks, splits, bursts, solid shuts, pipe, porosity, inclusions,
folds, seams and other similar defects.
3.6.1.1 Body cavity.  The body cavity shall be free of scale,
fins, burrs, draw marks, laminations, imbedded foreign matter, pits,
and sharp edges.
3.6.2 Fuze adapter.  The fuze adapter shall be free from
cracks, splits, cold shuts, laminations, or other similar defects.
3.6.3 Visual standards (internal and external).  Visual
standards for evaluation of metal defects shall be established for
each contract after the first month's production or whenever
requested by the procuring activity.  However, the establishment of
visual standards shall not waive the requirement for compliance with
3.6.1 and 3.6.2.
3.7 Brazed joint.  Braze metal must be visible for 360 degrees
on the exterior surface.  The braze need not be flush with the
outside surface; however, a single discontinuity must not exceed
1/8" with a total accumulation of 1/2" around the periphery. Braze
metal must be visible throughout discontinuity when viewed with a 4X
magnification and light source.
3.7.1 Joint quality.  The brazed joint shall be achieved in a
manner which will minimize entrapped slag, voids, unwetted or
unbonded areas and other brazing defects.  The aggregate area of
these defects shall not exceed 15% of the area of the faying
surfaces, and the maximum extent of a defect shall not exceed 50% of
the overlap distance (width) of the joint.
3.8 Ballistic performance (proving ground).  The projectile
body assembly shall reveal no evidence of failure when tested at
excess pressure.  Body assembly failure shall be:
a.  Projectile body or fuze adapter deformation
attributable to noncompliance with drawing or specification
requirements.
