than ten indications, whether in one plane or multiple planes, are permitted in any four inch
length.
3.2.9.5.1.3 Cracks. All cracks are rejectable.

article ballistic test shall not be required provided (a) the manufacturer, within 37 months,
has produced acceptable plates within the same nominal thickness ranges of table VI and
(b) the production conditions are the same as for previously accepted plates. A supplier
who has previously met the first article requirements shall furnish the procuring activity
with the pertinent data relative to compliance with first article test.
4.2 Conformance inspection. The acceptance examination under 4.5 and the tests under 4.6
shall serve as a basis for the acceptance of individual production lots.
4.3 Lot. A lot shall consist of all production and ballistic test plates of the same melt of
steel, of the same thickness, having the same treatment, and heat treated with the same
thermal cycle in the same production furnace(s) in the same facility. When specified by the
