17、vens in the test fixture of 4.6.7. All units shall fire and meet the requirements of 3.7. The criteria of acceptance is as stated in 4.6.8. 4.43 Failure. Failure of the sample to pass the above tests shall be cause for rejection of the first article sample. 4.5 Quaiity conformance inspection. Qualit
18、y conformance inspection shall consist of the tests and examinations of Table II. 4.5.1 Lot size. Unless otherwise specified (see 6.2), the production lot size shall not be less than 181 nor greater than 800 cartridges. Primary components from only one lot shall be used in one lot of cartridges, how
19、ever one lot of primary components may be used in more than one lot of cartridges. 4.53 Sampling. Unless otherwise specified, and when applicable, the sampling plans and procedures used in the determination of the acceptability of products submitted by a supplier shall be in accordance with the prov
20、isions of MIL-STD-105. The ballistic sample shall be selected in accordance with Table m. An additional 5 cartridges shall be randomly selected with the test sample for investigative purposes. 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-. b 999

24、lassification symbol indicates the serial number of the test or examination. Tests and examinations which are not annotated with a classification code are classified minor. 24 5 30 5 4.6 Tests and examination. 4.6.1 Visual inspection. Examine all completely asemble cartridges and reject those having
25、 any of the defects noted in 3.5.1. 4.63 Primer verification.
