8、ONAL CEMS DT-14 INTERNATIONAL CEMS B-50 4.0 GENERAL REQUIREMENTSBefore production approval is granted, all parts shall be functionally tested by the TDTC Technical Development Group. The molder shall supply parts for such tests based on materials and manufacturing processes that can be routinely use
9、d on a production basis. The minimum process and test data to be supplied with test/prototype parts is indicated below. 4.1 SMC Material A complete description of the SMC material(s) used in the part shall be provided. This shall include the molders compound number; the type and percentage by weight
10、 of the resin, glass, and filler; and the viscosity of the system. Tolerances or process control limits for these factors shall be included. This document is restricted and may not be sent outside International Truck and Engine Corporation or reproduced without permission from Corporate Technical St
11、andards. Suppliers are required to assume all patent liability. 2006 International Truck and Engine Corporation AUGUST 2006 Page 1 of 4 2NUMBER: TITLE: Development and Quality Control Procedures REVISION: TMS-9523 for SMC-FRP PartsD This document is restricted and may not be sent outside Internation
12、al Truck and Engine Corporation or reproduced without permission from Corporate Technical Standards. Suppliers are required to assume all patent liability. 2006 International Truck and Engine Corporation 4.1.1 SMC Material Properties Physical property data for the SMC material(s) (flat panel data) w
13、ill be submitted. Specific details of properties to be reported will be agreed upon between TDTC Materials Engineering and the supplier. 4.2 Charge Pattern A drawing of the charge pattern showing the number of plies, the charge weight, and the dimensions of the charge, will be provided. 4.3 Molding
14、Conditions A description of the molding conditions will be provided This shall include the mold temperatures (core and cavity), press closure speed, cycle time (time mold is closed) and tonnage exerted on the mold during closing. 4.4 Glass PatternPhotographs of a burn-off or an X-ray of the entire p
15、art clearly showing glass pattern will be provided. Identification of severe flow or knit line conditions shall be shown. 4.5 Molded Part PropertiesPhysical properties of the molded part as per Navistar Spec. D-22, at locations indicated on the part drawing will be provided. 4.6 Functional TestingFu
16、nctional testing will be performed by TDTC Technical Development Group. If the functional tests show deficiencies in the molded parts, the molder will be asked to alter or modify the material and/or production process. If material and/or process changes are made, the molder shall resubmit new parts
17、for retesting and provide new process/test data as required by Section 4 of this specification. 4.7 Class A Exterior SurfacesParts considered to be Class A, produced with IMC as per TMS 9012, shall have a surface reading of 100 maximum on the Loria scale as per CEMS DT-14. Examples of such parts are
18、 hood skins, fender extensions and sunshades. The readings shall be taken from a flat section of the part, away from edges, ribs, bosses etc. on an unpainted surface. Material may be qualified for this criterion from flat panels. This testing will be in accordance with International CEMS Test Method
19、 DT-14. Results of this qualification will be included in the Pre-Production Part Approval package submission to TDTC Materials Engineering. 4.7.1 Initial Submissions The Loria test method (DT-14) is intended for initial submissions only, e.g. new material qualifications or PPAP packages. This quali
20、fication standard is not meant to be an ongoing test requirement. Once certified, the material shall be considered approved for surface. Any changes to the material formulation or manufacturing process would require another Loria submission. 4.7.1.1 Molding Tool/DiesOn initial submissions for part q
21、ualification, data on the molding tool surface finish will be provided with the Loria test results. 4.8 Pre-Production Part ApprovalPre-production approval of all parts referencing this specification is required prior to acceptance of PPAP or production parts. Approval of the parts shall be in writi
22、ng from TDTC Materials Engineering to the supplier, to International Purchasing and Supplier Development, and to the International assembly plants involved.

25、ng, and International Quality Control personnel. 5.0 QUALITY After approval of the molders material and process, all parts must be produced exactly as described by the above procedure. No changes will be allowed without written approval of the Truck Development and Technology Center (TDTC). Field fa
26、ilures caused by unapproved changes in m rials or process shall be the sole responsibility of the molder. ate6.0 SOURCE APPROVAL AND QUALITY CONTROL6.1 Supplier RequirementsAll suppliers to International Truck and Engine are required to be registered to ISO 9001 Quality System Requirements. Internat
27、ional 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 furnish copies of registration certificate
28、s to their International Corporate Buyer upon request. 6.2 ApprovalParts 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 processing practices are permitted
29、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 Materials Engineering at TDTC and International Purchasing and Supplier Development of the proposed change(s). Test data
30、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. 6.3 Process ControlThe supplier shall either perform and repo
31、rt results of tests on specific lots of parts produced 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, Materials Engineering and/or the quality control manager of the
32、 using International plant may determine testing and reporting requirements on specific products. 7.0 DESIGNATION ON DRAWINGS This specification is applied to parts by the addition of a material note as follows: “Material and Process as per TMS 9523” AUGUST 2006 Page 3 of 4 4NUMBER: TITLE: Developme
