The polyester fibers specified in 3.2.1, 3.2.2, and 3,2,3 shall be intimately blended in the following proportions: Fiber 4.0 denier (3.2.1) 1.6

17、5 denier (3.2.2) 1.65 denier, coated (3.2.3) Percent o blend (+/- 5) 25 37.5 37.5 3.3.2 Batting fabrication. The intimate fiber blend specified in 3.3.1 shall be made into batting by air-laying or card/cross lapping fibers into a web which is then consolidated by needlepunching to achieve the battin

18、g weight and thickness requirements specified in table I. The consolidated batting shall be heat set to bond the fibers. A timeltemperature exposure shall be established for heat treatment which enables the binder fibers in the batting center to be activated without providing excessive heat exposure

19、 (excessive heat exposure can result in a harsh surface hand). 3.4 Physical requirements. The finished bonded batting shall conform to the requirements specified in table I, 3.4.1 and 3.4.2 when tested as speci- fied in 4.4.3.

22、.2 Launderabil-ity. The laundered batting shall show no greater batting separation, thin or thick spots, or curling than the batting before laundering when viewed over a black backgrcund. The laundered batting shall not demonstrate a thickness reduction greater than 10 percent from its measured thic

23、kness before laundering when tested as specified in 4.4.3. 3.5 Length and put-up. For Government procurement only, unless otherwise specified (see 6.2), the batting shall be furnished in continuous lengths of 30 yards each, and shall be put-up as specified in 5.1.1. 3.6 Workmanship.

QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the contracto

25、r 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 contractor may use his own or any other facilities suitable for the performance of the inspection requirements specif

26、ied 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. 3.0 4 Provided by IHSNot for ResaleNo

27、reproduction or networking permitted without license from IHS-,-,-MIL-B-44346(GL) 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 a become a part of the contractors overall inspection system or quali

28、ty program, 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 manufa

29、cturing operations, is an acceptable practice to ascertain conformance to the 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. 4.1.2 Certificates of compliance. When cert

30、ificates of compliance are sub- mitted, the Government reserves the right to inspect such items to determine the validity of the certification. 4.2 Classification of inspections. The inspection requirements specified herein Ge classified as follows: a. First article inspection (see 4.3). b. Quality

31、conformance inspection (see 4.4). 4.3 First article inspection. When a first article is required (see 3.1), it shall be examined for the defects specified in 4.4.2 and tested for the characteristics specified in 4.4.3. The presence of any defect or failure of any test shall be cause for rejection of

32、 the first article. 4.4 Quality conformance inspection. Unless otherwise specified, sampling for inspection shall be performed in accordance with MIL-STD-105, 4.4.1 Component and material inspection. In accordance with 4.1, components and materials shall be inspected in accordance with all the requi

33、rements of referenced documents unless otherwise excluded, amended, modified, or qualified in this document or applicable purchase document. 4.4.1.1 Component and material certification. A certificate of compliance may be acceptable as evidence that the characteristics listed in table II conform to
