DECEMBER 2014 Page 2 of 4 4.0 GENERAL QUALIFICATION Individual parts of the composite/assembly must meet all of the requirements of the material specification(s) shown on the engineering drawing for the part and/or
11、subassembly in addition to meeting all requirements of this specification. 4.1 Tooling requirements Selection of tooling materials, construction methods and maintenance procedures shall be such that a minimum of 30,000 parts can be produced without deterioration of the surface finish. After the init
12、ial production (30,000 pieces), repair of the molds is restricted to a maximum of 25% of the mold surface and such repair shall not result in degradation of the surface quality of the part. 4.2 Material Properties Property ASTM Method Unless otherwise specified DCPD Requirement Density, max, kg/m3 D
13、 792 1.05 Water absorption (24 hrs), max. D 570 0.5% Tensile Strength, min D 638 6.5 ksi Tensile Modulus, min D 638 250 ksi Flexural Strength, min D 790 10 ksi Flexural Modulus, Tangent, min D 790 250 ksi Gardner Impact, -20C, min CEMS DT-4 8.0 ft-lbs 4.3 Part Marking As an aid to recovery and recyc
14、ling of plastic parts, each part shall be marked to identify the type of polymeric material the part is comprised of. Part marking shall be in accordance with SAE J1344. Each part shall be identified so as to provide traceability to resin lot, molding date, and operator. 4.4 Surface Appearance This
15、requirement applies to parts identified on the drawing by a zone designation as per MPAPS G-9005. Parts such as hoods, fenders, or other highly visible parts are considered to be Zone I as per MPAPS G-9005. The surface is to be uniform, i.e. no areas of discontinuity, blisters, cracks, chips etc., a
16、re allowed. Small defects, such as pinholes, pits and small dirt particles, are to be minimized. No more than 12 of these small defects per part, or 6 within a 3-square inch (1935 mm2) area, is permitted. 4.5 Pre-paint Finish For parts requiring a pre-paint finish, the pre-paint treatment will confo
17、rm to the requirements of MPAPS G-9005. Parts requiring a pre-paint finish should be prepared in accordance with the resin/material suppliers recommended practice, e.g., per the Post Molding Guide for Metton . Surface appearance requirements will be in accordance with the zone descriptions in MPAPS
18、G-9005 for the primed surfaces. The pre-paint finish shall be adherent to the surface such that it will pass the Adhesion of Paint Test as per CEMS Test Method GT-5A.

20、neering at NAVISTAR the following information, relating to the production process, as described below. Information provided by the vendor to NAVISTAR shall be considered confidential. When identified by the supplier as “sensitive or proprietary”, such information will be considered confidential and
21、restricted to the appropriate Materials Engineering and Manufacturing Quality Control personnel. 4.6.1 A description of the constituent materials. This will include the molders material identification, level of promoter and system gel/cure times. Process Control limits for these factors should also
22、be included. 4.6.2 If reinforcing materials are used, a drawing of the reinforcement lay-up showing the physical dimensions of coverage. Include the tolerances of for those dimensions with respect to the location in the mold. 4.6.3 A general description of the molding process. This is to include the
23、 basic steps involved in producing the part, such as mold preparation, injection procedure, demolding, and any secondary and finishing operations. 5.0 QUALITY Initial production part samples will be selected and inspected jointly by both the supplier quality group and by product and supplier quality
24、 personnel. Samples will be inspected for cosmetic surface finish, component fit, edge finish and other characteristics as appropriate. These samples will be retained as reference inspection standards at the both vendor and NAVISTAR facilities. These samples will be considered standards of minimum a
25、cceptable finish quality for all future parts and will be maintained as reference standards both at the vendor and International facilities. No changes in the molding materials or production processes will be made after these initial production part samples have been approved. 5.1 Production Part Ap
26、proval Process (PPAP) Before final production approval is granted, sample parts will be submitted to NAVISTAR and to the appropriate NAVISTAR manufacturing plant(s) for approval in accordance with requirements of the Production Part Approval Process (PPAP) manual as per ISO 9001. 6.0 SOURCE APPROVAL
