32、n angular deviation of more than 5 minutes within a distance of not more than 20 inches on the screen when tested as specified in 4.5.1.2. It is not intended that the entire sheet be quantitatively surveyed for such variation in deviation but that localized imperfections which are suspected of being
33、 detrimental be evaluated by means of this test. Blemishes which do not individually reduce visibility through the plastic shall be disregarded unless they are grouped in an objectionable pattern. Minor defects within 1 inch from the nominal trimmed sheet edge shall be disregarded.3.17.1.2 Angular d

44、ed in the contract or order, the supplier 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 the specification whe
45、re such inspections are deemed necessary to assure supplies and services conform to prescribed requirements.4.2 Classification of tests: The inspection and testing of the plastic sheet material shall be classified as follows:a. Preproduction (4.2.2).b. Quality conformance inspection (4.3).4.2.1 Samp
46、ling instructions: The preproduction test sample shall consist of at least 10 square feet of trimmed sheet material in each of the thicknesses for which approval is desired. Individual sheets shall be at least 12 by 18 inches. Samples shall be tested at the contractors plant or a laboratory designat
47、ed by the Government, under the inspection of the procuring activity.4.2.2 Preproduction tests: Prior to actual procurement, the product which this specification covers shall pass the preproduction tests specified herein. If the product is later modified in any way, the modified form shall be subjec
48、ted to and shall pass the same preproduction tests. Preproduction tests will be repeated, upon request of the procuring agency, on material previously found satisfactory once during each calendar year.4.2.3 Tests: The preproduction tests shall consist of all the tests specified under 4.5.4.2.4 Teat
49、report: Except for the storage stability test, a statement shall be furnished to the procuring activity certifying that the materials and the test results meet the requirements of this specification. Approval of preproduction inspection shall not relieve the contractor of his obligation to meet the quality conformance inspection.Copyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license
