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.
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.
In this system, the ammunition manufacturers, in close cooperation with NATO, have set aside a batch also termed “lot” of ammunition they consider to be of very good quality and representative of ammunition that should be delivered to the armies in the following years. This batch is maintained at approved NATO test centres and distributed to the manufacturers involved.
When a new batch lot is delivered, a set of 20 reference cartridges are fired to see how they behave with the local equipment and with the current atmospheric conditions. Results are then compared to the reference values, as maintained by NATO and correctors delta values are computed.
Then, the current batch lot of ammunition is fired and the correctors are applied on the measured value giving a result “comparable” to the reference itself.

Each weapon will be individually tested, from an ammunition lot that produces a minimum corrected mean chamber pressure in accordance with the table below: The above proof round pressure requirements for the 9 mm and Unlike the civilian C. The advantage of this mounting position is that there is no need to drill the cartridge case to mount the transducer.
Drilling prior to firing is always a time consuming process fast quality control and feedback to production is essential during the ammunition manufacturing process. The disadvantage of this mount is that the pressure rises much faster ksitler in a drilled cartridge case. This slight error is not always well mastered and this causes a lot of discussion about the filter order, cutoff frequency and its type Bessel or Butterworth.
