39、.4 shall be performed on each cartridge lot in accordance with the test methods prescribed in 4.5. Sample size and acceptance criteria for each test shall be as specified. Only cartridges which have met the visual and dimensional requirements and which have been selected in such a manner that the sa

40、mple is representative of the entire lot shall be used in the tests. The selected cartridges shall be mixed thoroughly before being divided into samples for the various tests. 4.4.3.1 Projectile extraction. a. Failure of two or more sample cartridges to comply with the minimum requirement shall caus

41、e rejection of the lot. If one cartridge of the sample fails to comply with the minimum requirement, a second sample of 20 cartridges shall be tested. The lot shall be rejected if two or more cartridges of the combined sample fail to comply with the minimum requirement. b. Failure of four or more ca

42、rtridges to comply with the maximum requirement shall be cause for rejection of the lot. If more than one but less than four cartridges fail to comply with the maximum requirement, a second sample of 20 cartridges shall be tested. The lot shall be rejected if five or more cartridges of the combined

43、sample fail to comply with the maximum requirement. 4.4.3.2 Projectile torque. Failure of two of more of the sample cartridges to comply with the specified torque requirement shall cause rejection of the lot. If one cartridge of the sample fails to comply, a second sample of 20 cartridges shall be t

44、ested. The lot shall be rejected if two or more cartridges of the combined samples fail to comply with the applicable requirement. rejected if in any firing test one or more of the following casualties occur: 4.4.3.3 All cartridqe firinq tests.
