10. Rapidity at will. Same as preceding test, except that the pistol will be fired without aim into a butt at short range, and hits will not be considered.
11. Endurance. Pistol will then be fired deliberately 500 rounds as a self-loader, cooling after each 50 rounds.
12. Velocity. Same as paragraph 7, above.
13. Decreased charges. Pistol to be fired 12 rounds as a self-loader with cartridge in which the powder charge has been decreased so that the first four will give pressure of 25 per cent. less, the second four 15 per cent. less, and the last four 10 per cent. less than the service pressure.
14. Excessive charges. Pistol to be fired 5 times as a single loader, with cartridges in which the charge of powder is increased to produce a pressure in the chamber 25 per cent. greater than the regular pressure.
15. Pierced primers. Pistol will be fired once with a cartridge in which the primer has been thinned so as to insure piercing. Two rounds will then be fired to observe action.
16. Dust. With the mechanism closed and both ends of the barrel tightly corked pistol will be exposed, in a box prepared for that purpose, to a blast of fine sand for one minute. The surplus sand may then be removed by blowing thereon, jarring the piece, or wiping with the bare hand only.
In both cases pistol should be used as a self-loader, and in the second the cartridge may be removed and wiped, then reloaded. In case of self-loading failures to work in either case the piece will be tried by operating by hand.
17. Rust. The mechanism will be thoroughly cleansed of grease by boiling in a solution of soda, the ends of the barrel tightly corked and the pistol then placed in a saturated solution of sal-ammoniac for five minutes. After being hung up indoors for 22 hours, five shots will be fired into a sand butt, using pistol as a self-loader. In case the self-loading mechanism fails to work, the pistol will then be tried by operating by hand.
18. Supplementary Tests. Any piece which successfully passes the foregoing tests may be subjected to such supplementary tests, or repetitions of previous ones, to further determine its endurance or other qualities as may be prescribed by the Chief of Ordnance or by the board.
