Insensitive Munitions (IM) Testing
OTS are capable of testing of the vulnerability of munitions in accordance with STANAG 4439 (NATO Policy for the Development and Assessment of Insensitive Munitions).

The standard IM tests carried out include:
  • Slow Cook-off in accordance with STANAG 4382 where the munition is heated at 3.3ºC/h until an event occurs.
  • Fragment Impact in accordance with STANAG 4496 where the munition is attacked with high velocity fragments.
  • Bullet Impact in accordance with STANAG 4241 where the munition is attacked by a single 0.50 Cal AP bullet.
  • Sympathetic Reaction in accordance with STANAG 4396 where a single munition is detonated in its normal storage configuration.
  • Fuel Fire in accordance with STANAG 4240 where munitions are subjected to a liquid fuel fire until an event occurs.
  • Safety Drop Tests in accordance with STANAG 4375 where a munition is tested against severe impacts.

Other tests which may also be completed are:
  • Shaped Charge Jet Attack.
  • Underwater Shock Trials.
  • Rapid Decompression Trials.
OTS are also involved in the research and testing of materials and methods of reducing munition vulnerability to minimise the collateral damage from a munition event.
