VISUAL INSPECTION STANDARDS
FOR
SMALL ARMS AMMUNITION THROUGH
CALIBER .50
MIL-STD-636 5 June 1958
FOREWORD
This standard was prepared under the direction of the Office, Chief of
Ordnance, to be used to supplement specifications for small arms ammunition
through caliber .50. It replaces the following publication on the same subject:
ORD-SIP-S315, 1 January 1952.
This publication serves to create a military standard which evaluates and
illustrates a practical majority of defects assembled as a result of extensive
surveys covering all the small arms ammunition manufacturing facilities in this
country.
The format retains most of the features of the format of the publication it replaces because experience has proved that the numbering of illustrations to
conform to the numbering of visual defects in the applicable detail specifica
tions, special treatment of indexes and specialized grouping have served to
facilitate inspection, training, and general use.
