Ltop, the projectile orientation at impact must be recorded for proper polar zone alignment. The procedure for such a modification must be coordinated as early as possible with safety authorities, personnel involved in the actual modification, and personnel experienced in the conduct of the test.
Position the weapon mount forward of the radar so as to minimize the intercept angle of the radar relative to the line of fire; the intercept angle should be less than three degrees. The intent of ricochet itip is to give good confidence that the longest range ricochet has been determined for a given set of conditions.

In the absence of other guidance, use a sample itkp of 50 shots per condition. This test is equivalent to km of transport as loose cargo in tactical wheeled vehicles over rough terrain.
Ito weapons capable of being fired single shot, fire at target while checking sight alignment between each shot. For example, both documents detail a bullet impact test with very similar bullets; however the required bullet impact velocities are different. Recoilless Rifle ammunition may be delivered to a battlefield by parachute.
Support ammunition similar to the test ammunition should be provided if at all possible. Review the information to determine any effect on testing procedures such as environmental impact, temperature requirements, handling precautions, etc.
The target impact plate may block the path of projected fragments so its size and material must be carefully considered. The following orientations will generally be appropriate: After the hour exposure, remove the test items, and drain any accumulated liquid from magazines.
Slowly rotate the cartridge degrees in a vertical plane, stopping momentarily 4-2-6022 the bullet downward, and then continuing until the cartridge is projectile end up again. Support weapons firing from the open-bolt position are prepared by leaving the chamber empty and the bolt in the seared position, these weapons must be subjected to the same safety irop as for the closed bolt weapons. Fire any additional rounds needed to assure that the weapon is sighted on target.
As a minimum, the meteorologieal data itoop be reeorded at the start of the test firings and just after the last round is fired. Measurements shall inelude shell body length, bourrelet diameter, and rear ogive diameter. 4-2-062 plate surface must be clean and fiat in order to provide consistent results.
These conditions will include location in the package, orientation of drop, axis of vibration, and temperature. For artillery projectiles, half of the test sample is tested for 20 minutes at 5 Hz in the horizontal orientation and other half in the vertical base down position Projectiles using energy absorbing lifting plugs must have the plugs with the proper torque before and after the test.
The high humidity environment can also adversely affect propellants and other energetics if the cartridge is not totally sealed. Record the gross particulate size and the density of a sample. A mixture of live and simulated ammunition may be used to load the package. Screens may be constructed of any convenient material; fiberboard and light plywood are commonly used.
Also record any difficulties in operating the support weapon with the exposed ammunition such as excessive force required to charge the weapon, difficulty clearing stoppages, etc.
For longer ranges, determine if the impact angle is to be measured from the line of sight or from the 4-2-62 trajectory of the projectile at the target distance.
A statistician or mathematician familiar with the OSTR procedure should advise on each step of the procedure. The gage is itol in the barrel such that its ito; tip is in direct contact with the cartridge case which is not drilled. Each test is unique and must be based on the specific requirements for the cartridge.
If a physical target is used, inspect the projectile imprint for evidence of yaw, projectile deformation, etc.

It is not economically feasible to fire at a great many impact angles. Initial firings are done to establish the initial divergence of any debris; this information is then used to modify the witness screen layout to best determine the maximum range and divergence of the debris.
This procedure is done with the same methods as the R50 procedure except that the range is held constant while the velocity is varied between shots. Erect a itpp target behind the dowel array in the same manner as for the sheet material test, a minimum of ten meters is recommended. The ammunition is inspected, marked for individual identification, and its location within the container is recorded.
