30、d 1300 maximum. Cartridges required for all test purposes are selected from the production lot and will not be applied as a part of the quantity specified for delivery by the contract. Only primary components from a single lot shall be used in a production lot of cartridges. One primary component pr

31、oduction lot may be used in more than one cartridge production lot. Cartridges selected for the ballistic test shall be delivered to the activity designated by the contracting agency. 4.4.2 Sampling. Unless otherwise specified, and when applicable, the sampling plans and procedures used in the deter

32、mination of the acceptability of products submitted by a supplier shall be in accordance with the provisions of MIL-STD-414. Unless otherwise specified in the contract, order, or requisition, all samples for test purposes shall be provided at the expense of the contractor. 4.4.3 Classification of ch

33、aracteristics. The characteristics verified by the tests and examinations herein are classified as critical, major, or minor in accordance with WR-43. Tests and examinations that verify critical characteristics are identified by the symbol (C), and major characteristics by the symbol (M). The number

34、 following the classification symbol indicates the serial number of the test or examination. Tests and examinations which are not annotated with a classification code are classified minor. 4.5 Tests. 4.5.1 Primer. Verification shall be provided that the primers used were certified and accepted in ac

35、cordance with the requirements of 3.4. 4.5.2 Radiographic examination. 4.5.2.1 Primers. Prior to assembly, all primers shall be radiographically examined in accordance with MIL-STD-453. Primers having any of the defects specified in 3.4 shall be rejected. The primers shall be mounted on boards or tr

36、ays, preferably grooved, with the cup side perpendicular to the rays for the most revealing exposure. Pressure sensitive tape may be used as an aid in positioning the primers. The X-ray negatives shall be identified by item nomenclature and lot number. Primers are left mounted to the boards or trays

37、 until after the X-rays have been reviewed and defects identified to facilitate removal of defects. After screening, the X-rays with defectives identified shall be forwarded to the engineering agency designated by the procuring activity. 4.5.2.2 Cartridges. All cartridges shall be radiographically e

38、xamined in accordance with MIL-STD-453. Cartridges having any observable imperfections in assembly shall be rejected. The cartridges shall be positioned on their sides for the most revealing exposure. All cartridges shall be identified with serial numbers prior to examination. The cartridge serial n

39、umbers shall be in consecutive order beginning with the number O01 in each production lot. The cartridges shall be arranged on trays or boards in consecutive numerical order, and each radiograph shall carry a permanent identification of the cartridge displayed thereon. The radiograph identification

40、shall include the complete lot number, as stamped on the cartridges, and the span of serial numbers displayed. Discontinuities in serial numbers shall be identified on the X-ray. Defective cartridges found by the vendor shall be clearly identified on the X-ray and those defectives removed from the l

Conduct at least one test for each cartridge lot (or daily, whichever requires more testing) and such additional tests as considered warranted by variations in conditions or process. Samples may be collected at

43、 the site of loading from the powder container, or taken from cartridges prior to sealing the black powder charge in the cartridge. Weight loss per booster charge shall be ascertained with an accuracy of 0.2 milligram. The presence of moisture in excess of the limitations of 3.5.2 shall cause suspen

44、sion of loading until corrective measures have been taken. 4.5.4 Smokeless powder, condition. Smokeless powder shall be inspected in accordance with the applicable portions of paragraphs 1308-1318 of OP 5. Evidence of decomposition shall be cause for rejection. 4.5.5 Visual inspection.
