6、 assume all patent liability. 02000 International Truck and Engine Corporation AUGUST 2000 Page 1 of 3 NUMBER: TMS-2009 4.2 Microstructure Casting - Graphite 85% min of Types I and II per ASTM A-247 - Matrix shall consist of pearlite and ferrite with 2% max carbides well dispersed. Note: Mechanical

7、properties and microstructure shall be determined on suitably identified castings poured last in each heat lot. TITLE: REVISION: Nodular Iron, Pitman Arms c-1 4.3 Oualitv The casting must be crack free (after the peening operation used to fasten the drag link ball stud into the casting), as determin

8、ed by 100% inspection using dye penetrant, magnaflux, or other NDT technique. 4.3.1 The as-cast surfaces shall be shot-cleaned and free from cracks, porosity, cold shuts, scabs, and other defects which might affect the fatigue strength of the arm. The machined surfaces shall be free from all defects

9、. 4.3.2 The overall internal quality of the casting shall be sound and contain no gross or concentrated gas or shrinkage porosity. At the critical locations designated on the part drawing, there shall be no porosity or other defects, as revealed by radiography or other methods, larger than 1.5 mm (U

10、16 in) in diameter and no more frequent than one per 320 mm2 (0.5 in2) area. This specification does not imply that radiography inspection is required, but rather that a particular level of quality is expected and should be controlled by the vendor. 4.3.3 Critical castings or areas of castings subje

11、ct to more restrictive radiographic, magnetic particle, ultrasonic or other test requirements shall be specified on the part drawing. 4.3.4 Certification for soundness must accompany first pieces of new castings submitted for dimensional approval. Any changes in casting manufacturing procedure which

12、 may affect the soundness of approved castings must be confirmed by suitable means and certification submitted with first pieces. 4.3.5 All quality control and related test records shall be maintained for a minimum of five years and shall be subject to review by International personnel. 5.0 OUALITY

13、All product supplied shall be clean and free from dirt, oils, sharp edges, or defects harmful to product performance. 6.0 SOURCE APPROVAL AND OUALITY CONTROL 6.1 Supplier Requirements Suppliers must conform to the requirements of the INTERNATIONAL IQR Standard which includes conformance to the QS-90

14、00 (IS0 9001) Quality System Standard. A mutually acceptable Quality Control Plan as described therein is required for source approval to the requirements of this specification.

Suppliers are required to assume all patent liability. 02000 International Truck and Engine Corporation AUGUST 2000 Page 2 of 3 NUMBER: TMS-2009 6.2 Approval Parts supplied against contracts or purchase orders citing this specification shall be equivalen

16、t in all respects to those samples which were approved by the purchaser. No changes in formulation or processing 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 suppli

17、er shall notify Truck Development and Technology Center and International Purchasing and Supplier Development of the proposed change(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 ac

18、cordance with CFR Title 29, Part 1910 shall be submitted with the request for change. TITLE: REVISION: Nodular Iron, Pitman Arms c-1 6.3 Process Control The supplier shall either perform and report results of tests on specific lots of parts produced or provide statistical evidence of the lot having

19、been produced in a state of statistical control and with a process capable of providing all required properties. The part supplier and the plant metallurgist andor the quality control manager of the using International plant may determine testing and reporting requirements on specific products. 7.0

20、SHIPPING, PACKING AND IDENTIFICATION 7.1 Identification The part number and other identifying marks shall be located along the centerline of the arm surface perpendicular to the pitman shaft. These numbers, excluding the “timing“ mark, shall be shown as raised letters. If rework makes it necessary t

21、o alter or remove such letters by grinding, filing, etc., it shall be done carefully in one plane, removing no more than 0.41 mm (0.016 in), and leaving a flat surface. No marks or gouges perpendicular to the centerline of the arm shall be permitted. Special care shall be exercised to keep such grin

22、ding or filing away from the corner radii. Any numbers or marks added by stamping shall be done carefully and centered in the area selected. 8.0 DESIGNATION ON DRAWINGS TMS - 2009 9.0 APPROVED SOURCES R. H.
