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 IX, 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 the firing record of the ballistic test
plate and other pertinent data relative to compliance with first article. Neither first article nor
acceptance ballistic tests shall be required for plates ordered to thicknesses of more than 6.25

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 procuring activity
(see 4.3.1), production and ballistic test plates shall be allowed to be heat treated separately. The
test plate shall be heat treated in a production furnace.
4.3.1 Separately heat treated ballistic test plate. When the procuring activity allows a ballistic test
plate to be heat treated separately from the production plates it represents (see 6.2), it shall be so
stated in the data (see 6.7).
