REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements Fo
4、r Production Materials (WSS-M99P1111-A). 3.2 ENGINEERING REQUIREMENTS FOR DECORATIVE CERAMIC COATING 3.2.1 Appearance Appearance shall be judged as seen looking through the glass, and as specified on the print. Aged The decorative material shall exhibit a 3 or better AATCC rating (ASTM D 2616, gray
5、scale) after exposure to the environments listed in para 3.2.6. 3.2.2 Opacity - Decorative with Trademark Total visible light transmission through the ceramic band shall not exceed 1.0%. The measurement shall be made using a transmission black and white densitometer e.g. “Tobias Model TBX“, in direc

ENGINEERING MATERIAL SPECIFICATION WSS-M99P6-C1/C2 Printed copies are uncontrolled Copyright 2005, Ford Global Technologies, LLC Page 2 of 5 3.2.3 Adhesion of Decorative Material to Glass Test Method: Scribe the painted area with a sharp blade held at 90 to t
7、he glass surface. Determine adhesion of the decorative material initially and after exposure to the environmental conditions listed in paragraph 3.2.6 and 3.3. Remove the samples from the test environment and immerse in water per FLTM BI 104-01 for 24 h. Dry the test area, using a paper towel, cloth
8、 or air pressure and immediately apply fiber reinforced tape (per FLTM BI 106-01) to the scratched area with firm thumb pressure. Remove the tape by pulling at a 90 angle with moderate speed. Any removal of decorative materials more than 1.6 mm from the scribe line (excluding glass chips) or evidenc
9、e of blistering shall be basis for rejection. Note: Laminated samples will be evaluated prior to laminating. 3.2.4 Abrasion Resistance (excluding coating on the second/third surface for laminated glass) (Test Number 18 ANSI Standard Z26.1, 1977, January 26, 1977, as supplemented by Z26.1a, and incor
10、porated by reference of most current FMVSS 205, except that the wheel must be refaced with a new 600 grit paper disc prior to abrading each specimen.) Test Method: . Abrade the painted sample following test number 18 stated above. . Compare the abraded track to the unabraded portion of the sample vi
11、ewing the sample through the glass. . There shall be no visible change in the ceramic coating appearance when viewed through the glass and the total light transmission through the abraded area shall not exceed 1.0%. (Reference para 4.1). 3.2.5 Compatibility of Decorative Material with PVB (WSS-M99P6
12、-C1), When Coating is Applied to the Second/Third Surface (Figure 1) No more than 2 mm delamination of the decorative material to polyvinyl butyral (PVB) is permitted after exposure to the environments listed in paragraph 3.2.6. 3.2.6 Exposure Conditions 3.2.6.1 Heat Aging for 2 weeks at 90 +/- 2 C
13、3.2.6.2 Water Resistance (FLTM BI 104-01, 240 h) 3.2.6.3 Humidity Resistance (2 weeks humidity age at 98% relative humidity, and 50 +/- 2 C) ENGINEERING MATERIAL SPECIFICATION WSS-M99P6-C1/C2 Printed copies are uncontrolled Copyright 2005, Ford Global Technologies, LLC Page 3 of 5 3.2.6.4 Thermal Cy
