23、ts specified herein, unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in this specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements. 4.1.1 Responsibility for comp
24、liance. All items shall meet all requirements of sections 3 and 5. The inspection set forth in this specification shall become a part of the contractors overall inspection system or quality program. The absence of any inspection requirements in the specification shall not relieve the contractor of t
25、he responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling inspection, as part of manufacturing operations, is an acceptable practice to ascertain conformance to requirements; however, this does not au
26、thorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material. 4.1.2 General provisions. Unless otherwise specified herein, the provisions of MIL-A-48078 apply and form a part of this specification. Reference shall be made
27、to MIL-STD-109 to define quality assurance terms used herein. 4.2 Classification of inspections. The required inspections specified herein are classified as follows: a. First article inspection (see 4.3) b. Quality conformance inspection (see 4.4) 4.3 First article inspection. 4.3.1 Submission. When
28、 specified in the contract or purchase order, the contractor shall submit a first article sample consisting of one (1) pound of tetracene. The first article sample shall be obtained from the first production lot which has been produced by the contractor, using the same production processes, procedur
29、es and equipment as will be used in fulfilling the contract. All raw materials used in producing the tetracene shall be from the same sources as will be used in regular production. 4.3.2 InsDections to be performed. The first article sample may be subjected by the Government to any or all of the exa
30、minations or tests specified herein. 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-JJ -ri e: w E 3 z W m H 8 n $3 h2 MIL-T-46938C 9999906 1978817 734 in id a a O JJ k O -ri k a I) u -rl JJ I) -ri k o ci u a k w u w Lri W i3 n 2 E x z i2 z a v) z

32、hall be rejected. The Government reserves the right to terminate its inspection upon any failure of a sample to comply with any of the stated requirements. 4.4 puality conformance inspection. 4.4.1 Inspection lot formation. A lot shall consist of one or more batches of tetracene produced by one manu
33、facturer, in accordance with the same specification, or same specification revision, under one continuous set of operating conditions. Each batch shall consist of that quantity of tetracene that has been subjected to the same unit chemical or physical process intended to make the final product homog
34、eneous. The criteria and procedure for the assignment of lot numbers shall be in accordance with MIL-STD-1168. 4.4.2 Examinations and tests. a. Classification of characteristics. Quality conformance examinations and tests are specified in the following Classification of Characteristics paragraphs. T
35、he contractors quality program or detailed inspection system shall provide assurance of compliance of all characteristics with the applicable specification requirements utilizing as a minimum the conformance criteria specified herein. b. Alternative quality conformance provisions. Unless otherwise s
36、pecified herein or provided for in the contract, alternative quality conformance procedures, methods, or equipment, such as statistical process control, tool control, other types of sampling procedures, etc., may be used by the contractor when they provide, as a minimum, the level of quality assuran
37、ce required by the provisions specified herein. Prior to applying such alternative procedures, methods, or equipment, the contractor shall describe them in a written proposal submitted to the Government for evaluation (see 6.7). When required, the contractor shall demonstrate that the effectiveness
38、of each proposed alternative is equal to or better than the specified quality assurance provision(s) herein. In cases of dispute as to whether the contractors proposed alternative(s1 provides equivalent assurance, the provisions of this specification shall apply. All approved alternative provisions
39、shall be specifically incorporated into the contractors quality program or detailed inspection system, as applicable. 7 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-T-46938C = 999990b 197819 507 m u -rl lJ m -rl k a, lJ u a k (d A u rl a u -4

42、s emphasized that all applicable safety rules, regulations and procedures must be followed in handling and processing. 4.4.3.1 Samplinq. Obtain two random 30 gm samples from each batch of tetracene being submitted for inclusion in a lot. The samples shall be obtained from the process vessel prior to
43、 packout using procedures described in ASTM-E300 for slurries. 4.4.3.2 Testinq for batch acceptance. One sample obtained according to 4.4.3.1 from each batch shall be tested in accordance with the applicable test methods of 4.5 for conformance with the requirements for color and appearance (see 3.2)
