8、SS-M28P1-B1/B7 Copyright 2015, Ford Global Technologies, LLC Page 2 of 24 3.4 APPEARANCE Automotive windows are defined as “appearance items“ according to AIAG (Automotive Institute Action Group) Production Part Approval Process (PPAP). This requires that adequate approval of appearance criteria mus

9、t be defined and adhered to. Since this specification is the sole definition of such criteria, adherence to it satisfies the intent of PPAP Appearance Item Requirements, therefore, no additional appearance approval reporting is required. 3.5 TRADEMARK The trademark shall meet all criteria of the Ame

10、rican National Standard Institute (ANSI) for conformance to North American requirements or shall meet all the criteria for the local or intended market requirements. Mandatory information required in the Trademark: the American Standard number (AS no.), Manufacturers DOT Identification, Date Code (m

11、onth year), Material Construction Identification (M number), and Manufacturing Plant Identification. Manufacturers Logo (opt) and Material Description (opt). Examples are shown in para 4.1. The trademark shall also include any additional information required by the country of intended use. The trade

12、mark shall be legible from inside or outside the vehicle. Location of the trademark shall be designated and/or approved by all responsible activities of the Ford Motor Company. The trademark location shall be shown on the engineering drawing. The trademark may be applied using ceramic coatings in gl

13、ass or via a printing, laser part marking tool marking, film lamination, or film insert molding (FIM) procedure in polycarbonate. In the case of polycarbonate glazing the method or methods allowable shall be specified on the engineering document. 3.6 GLAZING CONSTRUCTION The glazing material constru

14、ction, including color, thickness, gradient band, coating, grid lines, obscuration pattern (such as on moon roofs), and tolerances to these items shall be as specified on the engineering drawing. 3.7 VISIBILITY DISTORTION The finished part needs to be visually inspected per the RQT-011101-012053 Opt

15、ical Distortion Test. This inspection is to be included in the manufacturers control plan as agreed upon by both Materials Engineering and Design Engineering. Boundary samples signed off by PVT, STA and PD Engineering will be used to establish the threshold of an acceptable part. . 3.8 GOVERNMENTAL

16、REQUIREMENTS The glass must meet the applicable Regional Standards and Regulations; for North America FMVSS 205, for Europe ECE and for China GB656 or as specified by Engineering Drawing. 3.9 EDGE FINISH (SAE J673) The edge requirements of finished parts shall be as specified on the engineering draw

17、ing. Typically edge finish numbers 1, 2, 3, 4 or 5 are used for automotive glazing applications. ENGINEERING MATERIAL SPECIFICATION WSS-M28P1-B1/B7 Copyright 2015, Ford Global Technologies, LLC Page 3 of 24 3.10 TOTAL GLAZING THICKNESS Nominal glazing thickness of finished parts, including the toler

18、ance, must be as shown on the engineering drawing. 3.11 GRADING AREAS FOR DEFECT DETERMINATION These areas shall be specified on the engineering drawing. Refer to Figures 1, 2, 3, 4 and 5. The following grading areas have been identified to allow variation in appearance defect requirements: WINDSHIE

19、LDS, FRONT DOOR GLAZING, AND OTHER GLAZING AREA A Central area of the glazing out to area B (excluding mirror button foot print). AREA B Painted areas, including dot patterns, mirror button footprint and gradient band. AREA C Nonvisible area of the glazing covered or concealed by a module, molding o

20、r weatherstrip by adjacent componentry or system coverage as identified on engineering drawing. Area designation may be surface dependent. 3.12 INSPECTION METHOD for determining appearance flaws The glazing shall be examined in true view position under diffuse lighting conditions with 270 +/- 50 lux

21、 illumination measured facing the center of the white grid board at a distance of 20 +/- 2.5 cm. The part shall be examined by looking through the part with it positioned 50 - 90 cm from the observer (arms length). The observers eye shall be level with the center and perpendicular to the part (see F

22、igure 6). An appearance item will be considered a flaw only if it is detected within 6 seconds (for body glass) and within 15 sec (for windshields and backlites) without being highlighted. If an appearance flaw is observed, the applicable specification requirements must be referenced to determine if

23、 the flaw is acceptable. Edge quality of the part may be evaluated by viewing the perimeter of the part under the same inspection conditions.
