3、RRENT REVISION This specification may involve hazardous materials, equipment, and procedures. This specification does not purport to address all of the safety issues associated with its use. The user is responsible to consult appropriate safety and health practices and to determine the applicability
4、 of regulatory limits prior to use. 1.0 APPLICATION This specification is applied to aid in controlling procedures used to develop critical parts molded from SMC reinforced plastics specified as per Navistar MPAPS D-22. Parts, such as tilt hoods, cowl panels, and heater cases, are typical applicatio
5、ns. The objective of this specification is to control material flow, and the physical and mechanical properties developed in the prototype parts and insure reproducibility between the prototype, qualification, and production SMC/FRP parts. 2.0 SCOPE This specification covers the production process d
6、ata, test analysis data, and sample parts that the molder is required to submit. Requirements for Quality Control of production parts are also covered. 2.1 Restricted Chemical Substances Effective January 1, 2007, all product supplied to the requirements of this specification must comply with the re
7、quirements of the MPAPS B-50 specification. 3.0 REFERENCE DOCUMENTS Unless otherwise specified, the latest issue of all referenced standards shall apply. The following standards, specifications and regulations are referenced in this specification. Quality System Standard ISO 9001 or TS-16949 NAVISTA
8、R MPAPS D-22 International IQR Quality Standard NAVISTAR MPAPS G-9012 CFR Title 29, Part 1910 NAVISTAR MPAPS DT-14 NAVISTAR MPAPS B-50 4.0 GENERAL REQUIREMENTS Before production approval is granted, all parts shall be functionally tested by the Navistar Materials Group. The molder shall supply parts
9、 for such tests based on materials and manufacturing processes that can be routinely used 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 pro
10、vided. This shall include the molders compound number; the type and percentage by weight of the resin, glass, and filler; and the viscosity of the system. Tolerances or process control limits for these factors shall be included. NUMBER: MPAPS P-9523 TITLE: Development and Quality Control Procedures

Suppliers are required to assume all patent liability. 2016 by Navistar, Inc. OCTOBER 2006 Page 2 of 4 4.1.1 SMC Material Prope
12、rties Physical property data for the SMC material(s) (flat panel data) will be submitted. Specific details of properties to be reported will be agreed upon between Navistar Materials Engineering and the supplier. 4.2 Charge Pattern A drawing of the charge pattern showing the number of plies, the cha
13、rge weight, and the dimensions of the charge, will be provided. 4.3 Molding 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 cl
14、osing. 4.4 Glass Pattern Photographs of a burn-off or an X-ray of the entire part clearly showing glass pattern will be provided. Identification of severe flow or knit line conditions shall be shown. 4.5 Molded Part Properties Physical properties of the molded part as per Navistar MPAPS D-22, at loc
15、ations indicated on the part drawing will be provided. 4.6 Functional Testing Functional testing will be performed by Navistar Materials 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 materi
16、al and/or process changes are made, the molder shall resubmit new parts for retesting and provide new process/test data as required by Section 4 of this specification. 4.7 Class A Exterior Surfaces Parts considered to be Class A, produced with IMC as per MPAPS G-9012, shall have a surface reading of
17、 100 maximum on the Loria scale as per MPAPS DT-14. Examples of such parts are 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
18、panels. This testing will be in accordance with International MPAPS DT-14. Results of this qualification will be included in the Pre-Production Part Approval package submission to Navistar Materials Engineering. 4.7.1 Initial Submissions The Loria test method (MPAPS DT-14) is intended for initial su
19、bmissions only, e.g. new material qualifications or PPAP packages. This qualification 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
20、 Loria submission. 4.7.1.1 Molding Tool/Dies On initial submissions for part qualification, data on the molding tool surface finish will be provided with the Loria test results. 4.8 Pre-Production Part Approval Pre-production approval of all parts referencing this specification is required prior to
21、acceptance of PPAP or production parts. Approval of the parts shall be in writing from Navistar Materials Engineering to the supplier, to International Purchasing and Supplier Development, and to the International assembly plants involved.

23、nal Material/Process Information The supplier shall submit additional information, as necessary, to satisfy the objective of this specification. Information provided by the vendor to International per this specification shall be considered confidential. Distribution shall be restricted to appropriat
24、e Navistar Materials Engineering, Purchasing, 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 Navistar Mater
25、ials Engineering. Field failures caused by unapproved changes in materials or process shall be the sole responsibility of the molder. 6.0 SOURCE APPROVAL AND QUALITY CONTROL 6.1 Supplier Requirements All suppliers to Navistar International are required to be registered to ISO 9001 Quality System Req
26、uirements. International 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 regis
27、tration certificates to their International Corporate Buyer upon request. 6.2 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 processing prac
28、tices 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 Materials Engineering at Navistar and International Purchasing and Supplier Development of the propos
29、ed 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 accordance with CFR Title 29, Part 1910 shall be submitted with the request for change. 6.3 Process Control The supplier shal
30、l perform and report 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 cont
31、rol manager of the 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 MPAPS G-9523” NUMBER: MPAPS P-9523 TITLE:
