The breaking strength of the heat sealed seams shall be not less than 16 pounds when tested in accordance with Method A of ASTM D 882. See Figure 1. 3.6.2 Leakage. The c
15、over shall not leak or separate at the seam when tested as specified. 3.7 Workmanship. The finished map case shall be thoroughly clean, well finished, free from gels, pinholes, holes, cracks and blisters, fish eyes, mottling, particles of foreign matter and undispersed raw material. Raw edges shall
16、be free from nicks and cuts. 4 Redatow Requirements. The offeror/contractor is encouraged to use recovered materials to the maximum extent practicable, in accordance with paragraph 23.403 of the Federal Acquisition Regulation (FAR). 5 Product Conformance Provisions 5.1 Product Conformance. The contr
17、actor shall certify and maintain substantiating evidence that the product offered meets the salient characteristics and requirements of this Commercial Item Description and that the product conforms to the producers own drawings, specifications, standards and quality assurance practices. The governm
18、ent reserves the right to require proof of such conformance prior to the first delivery and thereafter as may be otherwise provided for, under the provisions of the contract. Reliance on contractor QA systems shall not relieve the contractor of the responsibility of ensuring that all products or sup
19、plies submitted to the government for acceptance comply with all requirements of the contract 5.2 Visual Examination. Case lots shall be inspected in accordance with Sampling Procedures and Tables for Inspection by Attributes, ANSUASQC 21.4, published by the American Society for Quality Control. The
20、 cases shall be examined for the defects listed below. 5.2.1 Defects. The case shall be examined for the following defects: not uniformly colorless and clear; not dull matte finish; objectionable odor; any blister or fish eye or unfused resin particles; seam not continuous, not uniform; poor heat se
21、al resulting in inadequate fusion; corners not rounded; any hole, crack, wrinkle, tear, sharp crease or cut; any spot, stain, or other discoloration which requires a cleaning agent for removal; not clean, evidence of dirt, grit, oil, or other foreign matter on or in map case; zipper does not work pr

Any dimension that is not within the established tolerance (+i inch, -0 inch) shall be classified as a defect. 5.3 End Item
24、Performance Testing. The end items shall be tested for odor, label adhesion, seam strength, crease strength and leakage. 5.3.1 Requirement for Odor . Determination of odor shall be made on samples freely exposed to circulating air at 75 degrees F +/- 5 degrees F (24 degrees C +/- 3 degrees C) for no
25、t less than 24 hours. 5.3.2 Requirement for label adhesion. Each case shall have a label that is directly printed, stamped or stenciled on the case. The contents, size and characters of the inscription, and the format shall be as follows; ITEM DESCRIPTION CONTRACT NUMBER STOCK NUMBER SIZE - minimum
26、of 18 points (approximately ?A inch) - minimum of 18 points (approximately ?A inch) - minimum of 18 points (approximately ?A inch) - minimum of 18 points (approximately ?A inch) CONTRACTORS NAME (bottom of label) - maximum of 18 points (approximately ?A inch 5.3.3. Seam Strength Requirement. Each sp
27、ecimen shall be cut 1 inch by 6 inches with the seam approximately in the middle and parallel to the short sides of the specimen. If the average breaking strength for any sample unit falls to meet the requirements specified, the lot shall be rejected. 5.3.4. Requirement for Leakage. The case shall n
28、ot leak or separate at the seam when tested as specified. 5.3.5 Odor test. Determination of odor shall be made on samples freely exposed to circulating air at 75 degrees F +/- 5 degrees F (24 degrees C +/- 3 degrees C) for not less than 24 hours. 5.3.6 Ink adhesion label test. The ink adhesion shall
29、 be determined in accordance with ASTM F 1842 except that the test shall be performed on the label of a finished case. The test area of the label shall be visually examined for legibility. 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-55192A
30、5.3.7 Seam strena test. The breaking strength of the heat sealed seams shall be not less than 16 pounds when tested in accordance with Method A of ASTM D 882. Each specimen shall be cut 1 inch by 6 inches from a finished case with the seam approximately in the middle and parallel to the short sides
31、of the specimen. The gage marks need not be applied and the elongation need not be measured. The initial separation between the grips of the apparatus shall be 2 inches and the specimen shall be placed in grips with the seam equidistant between the grips. The strength of the seam reported in pounds
32、to the nearest 0.1 pound shall be the average of 5 determinations per sample unit. 5.3.8 Leakage Test. The case shall be marked 5 inches from the inside of the seam and filled with water to the mark. The temperature of the water shall be 73.5 +/- 2 degrees F. The case shall then be suspended over a
33、dry receptacle for a period of 3 hours. At the end of the 3 hour period, the case shall be examined for seam separation and leakage of the water into the receptacle. 6.0 Packaging. Preservation, Packaging and Marking. Cases of one size only shall be packed in accordance with ASTM D 3951 except that
