Proof Testing of Ammunition and Explosive Powders for the Trade and Home Loader.

Under the rules imposed on Proof Houses in Europe and other countries, set by our governing body, the Commission Internationale Permanente (CIP).

Headquarters in Liege, Belgium - cartridge manufacturers are required to provide samples of their products to be subjected to test by the Proof House and, if satisfactory, may carry the Proof House and CIP mark (see right).

Although the same rules do not apply to home loaders, given that their products cannot be legally sold, in the interests of safety the Proof House affords those parties opportunity to batch test their ammunition to ensure that the associated breech pressures and velocities are within acceptable standards. By so doing it removes the potential for weapons being damaged, thereby injuring the user or, even worse, innocent bystanders. Previous tests of this nature in the past have indicated the poor standards adopted by such parties and the lack of uniformity between rounds of ammunition.

Similar tests can be made on various powder batches or powder types.

The ammunition is tested in the Proof House Laboratory using modern test guns which are linked to a computer to provide graphical presentations.
