23、horized disribution site from which a qualified product is processed, manufactured, finalized and/or shipped shall be listed on the qualified product list (see 3.2). 3.2.2 Provisions Governing Qualification The provisions governing qualification are specified in SD-6 3.2.3 Reliability The manufactur
24、ers reliability assurance program for connector accessories and assembly procedures shall comply with the AS9100 Aerospace standard for Quality Management System requirements. Other established and industry recognized quality assurance standards that assure all products produced conform to the contr
25、act requirements are acceptable. However, if used, it is the responsibility of the manufacturer to provide evidence of compliance to AS9100. The qualifying activity (QA) authority reserves the right to monitor, measure, and validate compliance at their discretion. SAE INTERNATIONAL AS81914 3 OF 173.

28、S-QQ-P-35. 3.4 Design and Construction 3.4.1 Convolution Type The tubing supplied under this specification shall have a right hand helical thread or annular type convolution (see Figure 1). Type 1 = Helical and Type 2 = Annular. The availability of each is noted on the applicable detail specificatio
29、n sheet. 3.4.2 Classes Class “0” designates a tubing shape having close convolutions with higher flexibility and bend radius characteristics than the standard convolution tubing shape. The availability of each is noted on the applicable detail specification sheet and forms a part of the part identif
30、ying part number. Class “1” designates a tubing shape having standard convolutions with less flexibility and bend radius characteristics then the close convolution tubing shape. The availability of each is noted on the applicable detail specification sheet and forms a part of the part identifying pa
31、rt number. 3.4.3 Drain Holes Drain holes shall be .110/.05 (2.8/1.3) in diameter and be in a pattern such as helical or spiral at 60 radial spacing on every other convolute.

32、 applicable (see Figure 1). 3.4.4 Helix Reinforcement When helix reinforcement wire is specified, the wire shall be retained in each of the valleys of the convolute tube form and shall meet the performance requirements specfied in 4.7.13. The diameter of the wire shall not exceed the maximum outer d
33、iameter of the tubing and the minimum inside diameter of the tubing may be decreased .015 (.38 mm) inches maximum from the minimum inside diameter specified on the applicable detail specification sheet (see Figure 1).

34、e Requirements Tubing shall meet the performance requirements specified herein when tested in accordance with the specified methods of section 4. 3.6 Construction Details When examined as specified in 4.6.1, all construction details - dimensions, tolerances, weights, and convolutions per inch shall
35、be in accordance with the applicable detail specification sheet. 3.7 Physical Property Requirements Physical properties shall be as specified in Table 2. The specific values shall be in accordance with the applicable detail specification sheet. 3.8 Workmanship When examined visually, the convoluted
36、tubing shall be free from internal voids, blisters, bumps, tears, pinholes, longitudinal seams, cracks, foreign matter or other defects that would be detrimental to performance as specified herein and on the individual detail specification sheets. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility f
37、or Inspection Unless otherwise specified in the contract or purchase order, the supplier is responsible for the performance of all inspection requirements as specified herein. Except as otherwise specified in the contract or purchase order, the supplier may use his own or any other facilities suitab
38、le for the performance of the inspection requirements specified herein, unless disapproved by the qualifying activity. The qualifying activity reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed necessary to assure supplies and servic
39、es conform to prescribed requirements. 4.1.1 Responsibility for Compliance All items must meet the 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 requi
40、rements in the specification shall not relieve the contractor of the responsiility of assuring that all products or supplies submitted to the qualifying activity for acceptance comply with the requirements of the contract. Sampling in quality conformance does not authorize submission of known defect
41、ive material, either indicated or actual, nor does it commit the qualifying activity to acceptance of defective material. SAE INTERNATIONAL AS81914 5 OF 174.1.2 Test Equipment and Inspection Facilities Test and measuring equipment and inspection facilities of sufficient accuracy, quality and quantit
42、y to permit performance of the required inspection shall be established and maintained by the contractor. The establishment and maintenance of a calibration system to control the accuracy of the measuring and test equipment shall be in accordance with ANSI/NCSLZ540-1. 4.2 Classification of Inspectio
