SCOPE This specification defines the minimum durability and performance requirements of hard, mold-in-color interior trim panels, moldings, overhead and floor consoles, and hard instrument panels where various
3、materials are combined to provide a trim assembly having decorative and/or functional features. 2. APPLICATION This specification was originally released for plastic mold-in-color and non-visible interior trim items such as door panels, center and overhead consoles, quarter panels, A-, B-, C-, and D
4、-pillar moldings, hard instrument panels, instrument panel components and garnish molding. Testing for mold-in-color components is detailed in Table 1 unless specified otherwise by Ford Engineering. Testing for non-visible components is detailed in Table 2 unless otherwise specified by Ford Engineer
5、ing. Testing must be done on parts unless part geometry does not allow. If that is the case, appropriate plaques with production grain and color can be used. 2.1 LIMITATIONS Excluded from this specification are the non resin components within the following assembly performance specifications; soft i

12、 etc.) and assembled onto actual or representative production support foundations. This includes not only all attaching points, but also any boundary conditions that may restrict movement, unless otherwise specified by the responsible PD Engineer. The retention methods, attachments, and supporting g
13、arnish moldings (if any), shall be the same as proposed for production. Measurement Locations Every twenty centimeters and at the points of greatest movement between the twenty centimeter marks along the parts outside edges and internal openings or as defined by PD Engineering. Some parts may have s
14、pecific measurement locations required by PD Engineering, which will override the 20 cm required. Part specific measurement locations to be signed off by PD Engineering prior to test. The “significant characteristics locations“ specified on the engineering drawing. For Upper A-Pillars: In addition t
15、o the locations defined above, measurement locations should be every 5 centimeters starting at the upper zero location and running along the glass and the weather seal edges (See diagram below). Applies to paragraphs 3.3.1 and 3.3.2. ENGINEERING MATERIAL SPECIFICATION WSS-M15P4-G Copyright 2016, For
16、d Global Technologies, LLC Page 3 of 10 Measurement Technique The movement at each measurement point shall be recorded in two directions: (1) in the x/y plane from the observers view, and (2) in the z-dimension direction into or out of the x/y plane from the observers view. The observers view shall
17、remain consistent always viewing from the front side of the part. Test Procedure Visually evaluate the part before, during, and after the test. Measure the part and record data at all specified locations at room temperature before and after cycling on the production support foundation or test fixtur
18、e. Any visual defects/imperfections must be noted in the test report, and signed off by PD Engineering for compliance. Upper A-Pillars: For 3.4.1 Short Term Heat, Humidity, and Cold cycle: Within the last 2 hours of the final cycle of high heat, photograph the parts with the same camera angle as on
19、the pre-test photo. For 3.4.2 Long Term heat: Within the last 24 hours of high heat test, photograph the parts with the same camera angle as on the pre-test photo. Subject the number of assemblies specified to each of the cycles that follow in paragraphs 3.4.1 and 3.4.2. Use test chambers with autom
20、ated programmable test cycles for the listed test conditions below.
