15、ry when tested as specified in 4.2.4.1. . 3.4 Functioning. The smoke pot shall ignite and emit a dense cloud of smoke within a maximum period of 50 seconds. The pot shall continue to emit under pressure a dense cloud of smoke for a period of no less than 8 nor more than 13 minutes without any interr
16、uption greater than 80 seconds, from the time the fuel block begins to burn until the smoke is no longer emitted under pressure when tested as specified in 4.2.4.2. 3.5 Workmanship.

17、 could affect its use. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract or pur- chase order, the contractor is responsible for the performance of all inspection require- ments (examinations and tests) as specified herein. Except as otherwi
18、se specified in the contract or purchase order, the contractor may use his own or any other facilities suitable for the performance of the inspection requirements specified herein, unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in
19、this specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements. 4.1.1 Responsibility for compliance. All items shall meet all requirements of sections 3 and 5. The inspection set forth in this specification shall become a part of the
20、 contrac- tors overall inspection system or quality program. The absence of any inspection require- 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-S-51235C 13 777770b 033357b B MIL-S-51235C ments in the specification shall not relieve the cont
21、ractor of the responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with ali requirements of the contract. Sampling inspection, as part of manufacturing operations, is an acceptable practice to ascertain conformance to requirements, however, this
22、does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material. 4.1.2 Objective evidence. The contractor shall provide objective evidence acceptable to the contracting officer that the requirements of 3.1 and sect
23、ion 5 for which specific inspection has not been provided in this specification have been satisfied. 4.2 Quality conformance inspection. 4.2.1 Lotting. A lot shall consist of the smoke pots of one interfix number, produced by one manufacturer, at one plant, from the same materials and under essentia
24、lly the same manufacturing conditions. However, no more than one lot of fuzes nor more than one lot of each sustainer or propellant mix ingredients, produced by one manufacturer shall be represented in any one lot of assembled smoke pots. 4.2.2 Sampling. . 4.2.2.1 For examination and nondestructive
