21、1.1 Responsibilit-y for compliance. All items shall meet. all requirements of sections 3 and 5. The inspections set. forth in this specificat ion shall become a part. of the cont-ract-ors overall inspection system or quality program. The absence of any inspection requirements in the specification sh
22、all not. relieve t-he contractor of the responsibility of ensuring that all products or supplies submitted t.0 the Government for acceptance comply with all requirements of t-he contract. Sampling inspect.ion as part of manufacturing operations, is an acceptable practice to ascertain conformance t.0

Unless otherwi se specif i ed herein or provi ded for in the contract, alternative qua1it.y conformance procedures, methods or equipment-, such as statistical process control , tool control, variables sampling or other types of sampling
29、 plans, etc. , may be used by the contractor when they provide, as a minimum, the level of quality assurance required by the provisions herein. Prior to applying such alternative procedures, methods or equipment, the contractor shall describe them in a written proposal submitted to the Government fo
30、r evaluation (see 6.6). When required, the contractor shall demonstrate that the effectiveness of each proposed alternative is equal to or better than the specified quality conformance provision(s) herein. In case of dispute as to whether the contractors proposed alternative(s) provides equivalent a
31、ssurance, the provisions of this specification shall apply. All approved alternative provisions shall be specifically incorporated into the contractors quality program or inspection system, as applicable. 7 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS

40、his speci.fication in accordance with 4.4.2 herein and Table I. - 4.5.2 Hardness t-est. 4.5.2.1 Requirement. Each basic melt ladle, whichever is the smaller, 25 projectiles shall be randomly selected and tested for relative hardness. Projectiles shall be tested in the zone where the obt-urating band
41、 groove will later be machined. The hardest. and softest projectiles from this group shall be subjected to tension t.esting in accordance with 4.5.3, 4.5.2,2 Test- procedure. The fest shall be performed using any automated hardness tester which will produce accurat-e repeatable results with readings
42、 for an acceptable projecti le between 25-80 percent of the full scale capability of the test- equipment. Operating procedures shall be as specified by the applicable equipment- manual, standard ASTM test methods and the following subject t-o approval by the Government representative: a, The hardnes
43、s tester calibration shall be t-ested at start- up, at least one each four hours of continuous operation, and after a layoff of three or more hours. b. The body shall be fixtured so that no rocking, shifting or deflection of the body will occur during the test 12 Provided by IHSNot for ResaleNo repr
44、oduction or networking permitted without license from IHS-,-,-MIL-B-71154 (AR) c. The hardness tester shall not produce indentations deeper than 25 percent of the indentor ball diameter or wall thickness of the project-i le in that zone. d. Hardness readings shall be taken at least- ten indentor bal
45、l diameters apart At- least two readings shall be taken per projecti le and averaged. Impressions shall be complet-ely removed on final machining. 4.5.3 Tensile test. Two specimens each shall be fabricated from the hardest and softest projectiles from the hardness test in 4.5.2. The specimens shall
46、be the largest- round specimens obtainable in conformance with the proportions shown in ASTH-E8, except. that. the grip areas may be less than full round sections. The t-ensi le specimens may be fabricat-ed prior to machining the obturator grooves. The cent-er of the tensile test specimens shall be
47、from the center or rear of the zone where the obturating band groove would normally be located. All specimens must meet or exceed t-he minimum t-ensi le strength requirements shown on drawing 12953576. The failure of any specimen to meet the tensile requirements of the drawing shall be cause for rej
48、ection of all projectiles from that month or basic melt. ladle of steel. If one basic melt. ladle is project-ed to be used in the manufacture of projectile bodies for several months, the total number of tensile specimens expected should be tested at the start- of that basic melt ladles use. 5. PACKAGING 5.1 Packing. The project-i les shall be packaged in containers in accordance wit.h the best. current. standards of industry so that- they will arrive in prime condition and can be stored in such a manner as to remain in that. condition. 5.2 Mark%.
