9、ies Steel wheels must meet the following tensile properties when tested in accordance with ASTM E 8. Tensile specimens will be taken from the flange region of the wheel. The testing must be performed on finished parts to ensure properties are representative of the finished part. Yield strength 275 M

10、Pa (43 ksi) min Ultimate tensile strength 390 MPa (56 ksi) min Elongation (in./in.) 24.0% min 4.3 Fatigue Performance The wheels will meet the following fatigue life requirements. For the new wheel designs, six samples for both radial and cornering fatigue shall be tested for initial qualification.

11、For periodic quality audit or if any material or process changes are made, the following tests will be performed per the test method in SAE J267: 4.3.1. Radial Fatigue: run at 1.8 load factor minimum is 1,000,000 cycles 4.3.2. Radial Fatigue: run at 1.6 load factor minimum is 3,000,000 cycles 4.3.3.

12、 Cornering Fatigue: run at 1.3 load factor minimum is 100,000 cycles The supplier can select the accelerated load factor as required, however any load factor not specified above requires the written approval of NAVISTAR Truck Wheel Systems Engineering. At least one sample of each test will be run un

13、til failure, preferably two samples. If only one is run to failure, then at least two others shall be run to 125% of the minimum requirement. 4.4 Balancing The 22.5 inch steel wheels shall have a maximum static wheel imbalance of 30 oz-in. The 19.5 inch steel wheels shall have a maximum static wheel

14、 imbalance of 24 oz-in. 4.5 Corrosion Resistance Painted steel wheels must meet the corrosion requirements set forth in MPAPS G-9009. 4.6 Welding All welds must be consistent with American Welding Society practices and requirements for steel. 5.0 QUALITY The wheels are to be free of burrs, sharp edg

15、es, and corrosion. All welds shall be free from porosity and other weld defects which might affect the performance of the wheel. Wheels reworked for cosmetic repair shall be identified for traceability. The surface finish and cosmetic appearance of the wheels will conform to the quality initially ap

16、proved by Navistar Industrial Design department and the receiving Plant Quality Control department. Master samples shall be retained by the supplier and the using plant for reference. 5.1 Leak Detection In the initial run all wheels must be leak tested by visual inspection of bubbles at a minimum pr

17、essure of 1241 kPa (180 psi) for a duration of 30 seconds minimum when fully immersed in water. Also, whenever a new PPAP is required, all wheels must be leak tested. Continuing leak testing will be performed on a per shift basis as agreed upon with the purchaser. Wheels failing the leak detection t

18、est shall be scrapped. No repair is allowed unless approved by NAVISTAR Quality Control and Materials Engineering.

19、Standards. Suppliers are required to assume all patent liability. 2014 by Navistar, Inc. DECEMBER 2014 Page 3 of 4 6.0 QUALIFICATION Engineering qualification of sources is required in advance of production shipments. Samples shall be accompanied by test data certifying that all requirements of the

20、specification have been met. Upon approval, styling master samples denoting the minimum level of acceptable appearance quality shall be developed and retained by the supplier and the quality department of each using NAVISTAR facility. 6.1 Quality Control Plan A Quality Control Plan for products supp

21、lied to the requirements of this specification will be established by mutual agreement between NAVISTAR and the supplier. Unless specific exception is noted, the following characteristics, where applicable*, shall be included in the plan as features for management by statistical process control.* *

22、Other characteristics for inclusion in the control plan may be specified on the engineering drawing and/or purchase order. * See NAVISTAR Engineering Design Standard A-16 7.0 SOURCE APPROVAL AND QUALITY CONTROL 7.1 Supplier Requirements All suppliers to Navistar are required to be registered to ISO

23、9001 Quality System Requirements. Navistar will also accept TS-16949 registration as long as the supplier can also fulfill all AIAG PPAP (Production Part Approval Process) documentation and approval requirements. Suppliers must maintain their certification with an accredited registrar and must furni

24、sh copies of registration certificates to their Navistar Corporate Buyer upon request. 7.2 Approval Parts supplied against contracts or purchase orders citing this specification shall be equivalent in all respects to those samples which were approved by the purchaser. No changes in formulation or pr

25、ocessing practices are permitted without approval. In the event that changes in material, properties, processing practices, construction, color, or labeling of the product are required, the supplier shall notify NAVISTAR Materials Engineering and Purchasing and Supplier Development of the proposed c

26、hange(s). Test data indicating conformance to all requirements of this specification, test samples, and new or amended or updated Material Safety Data Sheet(s) (MSDS), in accordance with CFR Title 29, Part 1910 shall be submitted with the request for change. 7.3 Process Control The supplier shall ei

27、ther perform and report results of tests on specific lots of parts produced using ISO 9001 or TS-16949 guidelines, or provide statistical evidence of the lot having been produced in a state of statistical control and with a process capable of providing all required properties. The part supplier and

28、the quality control manager of the using NAVISTAR plant may determine testing and reporting requirements on specific products. 8.0 SHIPPING, PACKING, AND IDENTIFICATION Shipping and identification shall be in accordance with Manufacturing Standard MS-D-13. All wheels shall have date identification f

29、or traceability.
