The add-on /additional weight shall not to exceed 10 percent. The process of applying finish to the cord shall cau
24、se no detrimental effect to the physical or chemical properties of the cord. Cord without finish will be labeled UNT or untreated. The supplier shall report on the test method and the type of finish used. The Spectra products that shall have a finish applied are listed in TABLE I. 3.8 Date of Manufa
25、cture (see 6.2). When required by the procurement document the textile manufacturer shall properly identify the age of the textile materials by placing a tag on the finished goods or label on the containers identifying the specification to which the material is manufactured, the lot number and the d
26、ate of manufacture. The date of manufacture is defined as the date (month and year) of the last manufacturing process that affects the physical characteristics of the material. 3.9 Water soluble material. No material shall be added for the purpose of weighing the cord. The water-soluble material of
27、the cord shall not exceed 10.0 percent when tested as specified in 4.4.5. 3.10 pH. The pH of the water extract of the finished cord shall be no less than 5.5 nor more than 9.0 when tested as specified in 4.4.5 (TABLE VI). 3.11 Put-up and length. Unless otherwise specified (see 6.2), the cord shall b
28、e put on non-returnable reels/spools. If the cord is put-up other than on reel/spool then the yardage in the package shall be converted to represent the yardage per reel/spool in order to maintain the current sampling and inspection requirements listed in this specification (4.4.2). Each reel/spool
29、shall not contain any knots or splices and shall be so wound that each turn and layer is free from entanglement. A plus tolerance of 10 percent shall be allowed on the total length of any reel/spool. The ends of the cord shall be heat sealed to prevent fraying. When cord is put up in 500 yard length
30、s, 20 percent of the total number of reels/spools in the lot shall be in one continuous length. The remaining 80 percent in the lot may contain pieced lengths (lapped on ends). These reels/spools shall contain no more than two pieces, with no piece less than 50 yards in length. When pieced lengths a
31、re contained on a reel/spool, the number and lengths of the pieces shall be marked on the identification ticket or label as specified in 3.12. 3.12 Identification. Each unit pack (reel/spool) of cord, interior container and exterior container shall be marked per contract requirements. An additional
32、label as noted below shall be attached to reel/spool if cord is more than one piece: - Number and length of pieces - Length of pieces of cord per reel/spool. 3.13 Workmanship. The fabricated cord shall conform to the quality and grade of product established by this specification. 4. VERIFICATION 4.1
33、 Responsibility for inspection. Unless otherwise specified in the contract or purchase Page 5 of 11 Copyright Protected: Do Not Copy!PIA-C-1200 order, the contractor is responsible for the performance of all inspection requirements (examinations and tests) as specified herein. Except as otherwise sp
34、ecified in the contract or purchase order, the contractor may use their own or any other facility suitable for the performance of the inspection requirements specified herein, unless disapproved by the procuring activity. The procuring activity reserves the right to perform any of the inspections se
35、t forth in this specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements. 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
36、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 the responsibility of ensuring that all products or supplies, submitted to the procuring activity for acceptance, comply with all
37、requirements of the contract. Sampling inspection, as part of manufacturing 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 procuring activity t
38、o accept defective material. 4.1.2 Certificates of Compliance. When Certificates of Compliance are submitted, the procuring activity reserves the right to inspect such items to determine the validity of the certification. 4.2 Classification of inspections. The inspection requirements specified herei
39、n are classified as follows: a. First article inspection (see 4.3) b. Quality 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 through 4.4.4.2 and shall be tested as specified in 4.4.5.
40、 4.4 Quality conformance inspection. Unless otherwise specified, sampling for inspection shall be performed in accordance with ANSI/ASQ Z1.4. 4.4.1 Component and material inspection. In accordance with 4.1, components and materials shall be inspected in accordance with all the requirements of refere
41、nced documents unless otherwise excluded, amended, modified, or qualified in this specification 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 the specifie
42、d requirements. (THIS SPACE LEFT INTENTIONALLY BLANK) Page 6 of 11 Copyright Protected: Do Not Copy!PIA-C-1200 TABLE II Component and material certification.

Every end item, prior to the visual examination in 4.4.3, shall be examined for the critical defects listed in TABLE III. Any end ite
44、m found to contain one or more critical defects shall be rejected. 4.4.3 End item visual examination. The cord shall be examined for the defects listed in TABLE III. All defects shall be counted regardless of their proximity to each other. The lot size shall be expressed in units of reels/spools. Th
45、e sample unit shall be one reel.spool. Ten percent of the total footage, but not less than 100 feet, shall be examined on each spool/reel in the sample. Acceptance sampling plan shall be determined by using Inspection Level II with an Acceptance Quality Limit (AQL) of 1.5 for major defects and 4.0 f
46、or total defects (major and minor combined). Any critical defect found during sampling inspection shall be cause for rejection of the lot represented by the sample.
