44、R) 4.4 Methods of inspection. 4.4.1 Primed case sensitivitv verification. The primed case sensitivity testing shall be performed as specified in SAAMI Technical Committee Manual Vol. IV Shotshell. Empty primed shotshell cartridges shall be tested for primer sensitivity. Two-thirds of the sample shal

45、l be tested at a height of 12 inches and one-third of the sample shall be tested at a height of 2 inches. If one or more cartridge primers fail at either height, the sample fails and a sensitivity rundown test shall be conducted. The sensitivity rundown test shall consist of a 25 cartridge test at e

46、ach 1 inch increment of height between O percent and 100 percent firing. If the average critical height (H) plus four standard deviations (4 sigma) exceeds 14 inches, or if the average critical height minus two standard deviations (2 sigma) is less than 1 inch, the lot of cartridges shall be rejecte

47、d. The average critical height (H) is defined as the mean height at which 50 percent of the primers being tested will fire. 4.4.2 Function and casualtv verification. Function and casualty testing shall be performed on a manual unaltered shotgun. Unpackaged cartridges shall be conditioned at temperat

48、ures of 70 f 10, -20 f 5, and 125 f 5 degrees Fahrenheit for a minimum of four hours. The weapon shall be fired until the total test sample quantity is reached. 4.4.3 Sound pressure level verification. The sound pressure level shall be tested with a government approved decibel meter microphone set u

49、p 1.5 f 0.5 feet to the right of the shooters left ear (assuming a right-handed shooter) or 1.5 f 0.5 feet to the left of the shooters right ear (assuming a left- handed shooter), with the weapon approximately 4 feet 8 inches above the ground. The test shall be performed outdoors, with no obstacles such as hills or buildings at least 30 feet from the test weapon. The wind shall be 2 miles per hour or less. A 10 gauge shotgun shall be used with
