32、 prior to or on the initial shipment of tubing to a purchaser, when a change in ingredients and/or processing requires reapproval as in 4.4.2, and when purchaser deems confirmatory testing to be required.4.2.2.1 For direct U.S. Military procurement, substantiating test data and, when requested, prep
33、roduction test material shall be submitted to the cognizant agency as directed by the procuring activity, contracting officer, or request for procurement.4.3 Sampling and Testing: Shall be as follows:4.3.1 For Acceptance Tests: Sufficient tubing shall be taken at random from each lot to perform all
34、required tests. The number of determinations for each requirement shall be as specified in the applicable test procedure or, if not specified therein, not less than three.4.3.1.1 When suitable test specimens cannot be cut from the tubing, a separate flat strip test sample shall be supplied upon requ
35、est. This strip shall be prepared from tubing 1.000 inch 0.063 (25.40 mm 1.60) in OD by 0.075inch0.008 (1.90mm0.20) in wall thickness, mechanically slit and flattened into a strip while being extruded, and cured in the same manner as production tubing.4.3.1.2 A lot shall be all tubing from the same
36、batch of compound processed in one continuous run and presented for vendors inspection at one time. An inspection lot shall not exceed 500 pounds (227 kg). 4.3.1.3 When a statistical sampling plan has been agreed upon by purchaser and vendor, sampling shall be in accordance with such plan in lieu of
37、 sampling as in 4.3.1 and the report of 4.5 shall state that such plan was used.4.3.2 For Preproduction Tests: As agreed upon by purchaser and vendor.4.4 Approval: 4.4.1 Sample tubing shall be approved by purchaser before tubing for production use is supplied, unless such approval be waived by purch
38、aser. Results of tests on production tubing shall be essentially equivalent to those on the approved sample.4.4.2 Vendor shall use ingredients, manufacturing procedures, processes, and methods of inspection on production tubing which are essentially the same as those used on the approved sample tubi
39、ng. If necessary to make any change in ingredients, in type of equipment for processing, or in manufacturing procedures, vendor shall submit for reapproval a statement of the proposed changes in ingredients and/or processing and, when requested, sample tubing. Production tubing made by the revised p
40、rocedure shall not be shipped prior to receipt of reapproval.Copyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-AMS 3654C SAE AMS 3654C- 8 -4.5 Reports: The vendor of tubing shall furnish with each shipme
41、nt a report showing the results of tests to determine conformance to the acceptance test requirements and stating that the tubing conforms to the other technical requirements. This report shall include the purchase order number, lot number, AMS 3654C, vendors material designation, size, and quantity
42、.4.6 Resampling and Retesting: If any specimen used in the above tests fails to meet the specified requirements, disposition of the tubing may be based on the results of testing three additional specimens for each original nonconforming specimen. Failure of any retest specimen to meet the specified
43、requirements shall be cause for rejection of the tubing represented. Results of all tests shall be reported.5. PREPARATION FOR DELIVERY: 5.1 Identification: Each package shall be permanently and legibly marked with not less than AMS3654C, size, color, quantity, purchase order number, manufacturers i
44、dentification, and date of manufacture.5.2 Packaging: 5.2.1 Packaging shall be accomplished to ensure that the tubing, during shipment and storage, will not be permanently distorted and will be protected against damage from exposure to weather or any other normal hazard.5.2.1.1 Standard packages sha
45、ll contain quantities as agreed upon by purchaser and vendor.5.2.1.2 Packaging of special sizes and lengths shall be as agreed upon by purchaser and vendor.5.2.1.3 A lot of tubing may be packaged in small quantities and delivered under the basic lot approval provided lot identification is maintained
46、.5.2.2 Packages of tubing shall be prepared for shipment in accordance with commercial practice and in compliance with applicable rules and regulations pertaining to the handling, packaging, and transportation of the tubing to ensure carrier acceptance and safe delivery. 5.2.3 For direct U. S. Milit
47、ary procurement, packaging shall be in accordance with MIL-STD-2073-1, Commercial Level, unless Level A is specified in the request for procurement. 6.
