context_page_description: NATO EPVAT testing is one of the three recognized classes of procedures used in the world to control the safety and quality of firearms ammunition.
  Beside this, there are also the Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives class of procedures and the Sporting Arms and Ammunition Manufacturers' Institute class of procedures.
  EPVAT Testing is described in unclassified documents by NATO, more precisely by the AC/225 Army Armaments Group.
  EPVAT is an abbreviation for "Electronic Pressure Velocity and Action Time". Action Time here means the time required between the ignition of the primer and the projectile leaving the barrel. This is a comprehensive procedure for testing ammunition using state-of-the-art instruments and computers. The procedure itself is described in NATO document AC/225 D/200.
  Unlike the C.I.P. procedures aiming only at the user's safety, the NATO procedures for ammunition testing also includes comprehensive functional quality testing in relation with the intended use. That is, not only the soldier's safety is looked at, but also his capacity to incapacitate the enemy.

  Beside this, there are also the Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives (C.I.P.) class of procedures and the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) class of procedures.
  EPVAT Testing is described in unclassified documents by NATO, more precisely by the AC/225 Army Armaments Group (NAAG).
  EPVAT is an abbreviation for "Electronic Pressure Velocity and Action Time". Action Time here means the (short amount of) time required between the ignition of the primer and the projectile leaving the barrel. This is a comprehensive procedure for testing ammunition using state-of-the-art instruments and computers. The procedure itself is described in NATO document AC/225 (Com. III/SC.1)D/200.
  Unlike the C.I.P. procedures aiming only at the user's safety, the NATO procedures for ammunition testing also includes comprehensive functional quality testing in relation with the intended use. That is, not only the soldier's safety is looked at, but also his capacity to incapacitate the enemy. As a result, for every ammunition order by NATO, a complete acceptance approval on both safety and functionality is performed by both NATO and the relevant ammunition manufacturers in a contradictory fashion.
  For this, a highly accurate and indisputable protocol has been defined by NATO experts using a system of reference cartridges.
  The civilian organisations C.I.P. and SAAMI use less comprehensive test procedures than NATO, but NATO test centres have the advantage that only a few chamberings are in military use. The C.I.P. and SAAMI proof houses must be capable of testing hundreds of different chamberings requiring many different test barrels, etc..
