The material shall consist of a polyethylene terephthalate film having one side coated with 99.5 percent pure aluminum deposited by the vacu
10、um deposition technique. a 3.2.1 Base film material. The base film material, including thickness, shall be specified by the procuring activity (see 6.2) and shall conform to the requirements of table I. TABLE I. Base film material. 3.2.2 Protective coating. When specified by the procuring activity (
11、see 6.2), the metallized side of film shall have a conversion coating applied in conformance with MIL-STD-171, Finish Number 7.3. 3.3 Physical property. 3.3.1 Aluminum thickness. The thickness of aluminum shall be 1 to 2 micro inches. 3.4 Workmanship. The metallized film shall show no blisters, bloo

QUALITY ASSURANCE PROVISI
13、ONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection requirements (examinations and tests) as specified herein. Except as otherwise specified in the contract or purchase order, the con
14、tractor may use his own or any other facilities suitable for the performance of the inspection requirements specified herein, unless disapproved by the Government. any of the inspections set forth in this specification where such inspections are deemed necessary to ensure supplies and services confo
15、rm to prescribed requirements. The Government reserves the right to perform 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 contractors overall inspection system or quality progr
16、am. The absence of any inspection requirements in the specification shall not relieve the contractor of the 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
17、operations, is an acceptable practice to ascertain conformance to requirements, however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material. 4.2 Classification of inspections. The inspection requi
18、rements specified herein are classified as follows: a. First article inspection (see 4.4). b. Quality conformance inspection (see 4.5). 4.3 Inspection conditions. Unless otherwise specified, all inspections shall be performed in accordance with the test conditions specified in 4.6. 4.4 First article
19、 inspection. When specified (see 6.2) a sample shall be subjected to first article inspection in accordance with all examinations and tests specified herein. 4.5 Quality conformance inspection. Quality conformance inspection for acceptance of material shall consist of all examinations, tests and ins
20、pection requirements of this specification and shall be performed by the supplier on a sample of metallized material representative of the shipment. A certified test report shall be furnished by the supplier and shall include the results of all examinations, tests and inspections. The Government res
21、erves the right to conduct any or all of the examinations and inspections prescribed herein on each lot of metallized material submitted by the supplier. 4.5.1 Lot formulation. Lot size shall consist of all the material submitted for acceptance at the same time, which has been prepared by the same m
22、anufacturer with no change in materials or processes and in one continuous period of operation. 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,- MIL-F-LI707bA 1 m 7777906 OY50Y7 7 m Lot size MIL-F-47076A (MI) Sample size 4.5.1.1 Sampling.
