28、quirements shown in Table 3 are acceptance tests and shall be performed on each lot: Table 3 - Acceptance tests Requirement Paragraph Reference Tensile Strength 3.3.1 Elongation 3.3.2 Dielectric Breakdown Voltage 3.3.3 Specific Gravity 3.3.4 Sizes and Tolerances 3.5 4.2.2 Preproduction Tests Tests f

29、or all technical requirements are preproduction tests and shall be performed 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

30、U. S. Military procurement, substantiating test data and, when requested, preproduction 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

31、Tests Sufficient tubing shall be taken at random from each lot to perform all 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

32、 from the tubing, a separate flat strip test sample shall be supplied upon request. This strip shall be prepared from tubing 1.000 inch 0.063 inch (25.40 mm 1.60 mm) in OD by 0.075 inch 0.008 inch (1.90 mm 0.20 mm) in wall thickness, mechanically slit and flattened into a strip while being extruded,

33、 and cured in the same manner as production tubing. 4.3.1.2 A lot shall be all tubing from the same 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

34、 been agreed upon by purchaser and vendor, sampling shall be in accordance with such plan in lieu of 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 approve

35、d by purchaser before tubing for production use is supplied, unless such approval be waived by purchaser. Results of tests on production tubing shall be essentially equivalent to those on the approved sample. SAE INTERNATIONAL AMS3653F Page 7 of 8 4.4.2 Vendor shall use ingredients, manufacturing pr

36、ocedures, processes, and methods of inspection on production tubing which are essentially the same as those used on the approved sample tubing. If necessary to make any change in ingredients, in type of equipment for processing, or in manufacturing procedures, vendor shall submit for reapproval a st

37、atement of the proposed changes in ingredients and/or processing and, when requested, sample tubing. Production tubing made by the revised procedure shall not be shipped prior to receipt of reapproval. 4.5 Reports The vendor of tubing shall furnish with each shipment a report showing the results of

38、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, AMS3653F, vendors material designation, and quantity. 4.6 Resampling and Retesting If any spec

39、imen 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 requirements will be cause for rejection o

40、f the tubing represented. Results of all tests shall be reported. 5. PREPARATION FOR DELIVERY 5.1 Identification Each package of tubing shall be permanently and legibly marked with not less than AMS3653F, size, color, quantity, lot number, purchase order number, manufacturers identification, and dat

41、e 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 shall contain quantities

42、 as agreed upon by purchaser and vendor. 5.2.1.2 Packaging of special sizes and lengths of tubing shall be as agreed upon by purchaser and vendor. 5.2.1.3 A lot may be packaged in small quantities and delivered under the basic lot approval provided lot identification is maintained. 5.2.2 Packages of

43、 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. Military procurement, p

44、ackaging shall be in accordance with MIL-STD-2073-1, Commercial Level, unless Level A is specified in the request for procurement. 6. ACKNOWLEDGMENT A vendor shall mention this specification number and its revision letter in all quotations and when acknowledging purchase orders. 7. REJECTIONS Tubing

45、 not conforming to this specification, or to modifications authorized by purchaser, will be subject to rejection. SAE INTERNATIONAL AMS3653F Page 8 of 8 8.
