The test part is mounted at vehicle installation angle and is located between the point source light and a white projection board so that the projected light passes through the glazing before reaching the projection board. The total distance between the point source light and

The test part is mounted at vehicle installation angle and is located between the inspector and a zebra board (see Glossary) so that the inspector can see the appearance of the stripes through the test part. The total distance betwee

The test part (excluding backlites) is rotated around its vertical axis as needed to simulate views from the side (cross car). The inspector observes the apparent shape of the stripes and reports the part unacceptable if an

31、SS-M99P6-C1/C2 (most current version) and be chosen from the Ford Approved Source list (ASL). They must also be specified on the engineering drawing. Conductive coatings, such as painted antennas and heated grids for backlites, must meet all requirements of WSB-M12P2-B/B2 (most current version) and

32、be chosen from the Ford Approved Source list (ASL). They must also be specified on the engineering drawing. The Tier 1 supplier must meet all USCAR-40 Lead Free Solder Validation Test Plan requirements with new lead free terminals. Any deviations must be approved by Core Glass Engineering. Electrica

33、lly heated glass must also conform to all SDS requirements. ENGINEERING MATERIAL SPECIFICATION WSS-M28P1-B1/B7 Copyright 2018, Ford Global Technologies, LLC Page 9 of 23 3.13.2 Polycarbonate Conductive inks and pastes the following are references for performance: Conductive pastes, such as printed a

34、ntennas and heated grids for backlites, must meet all requirements of WSB-M12P2-B/B2 (most current version). EHBs (electrically heated backlites) must also conform to all applicable SDS requirements. 3.13.3 Ceramic Frits Ceramic frit shall be as specified on the engineering drawing. Materials suppli

35、ed shall meet WSS-M99P6-C1/C2 (most current version), be chosen from the Ford Approved Source List (ASL) and meet all the requirements listed below. 3.13.3.1 Opacity The measurement shall be made using a transmission black and white densitometer e.g. “Tobias Model TBX” or similar, in direct contact

36、with the coating surface. For items B1, B2, B3, B4, B5, B6 UV light transmission must be less than 0.1% (UV absorption must be greater than 99.9%). 3.13.3.2 Color (FLTM BI 109-01 Visual Assessment, SAE J1545, Three-Angle CMC) Color shall match the Master Approved Sample color panel or the initial sa

37、mple as approved by Design Center, if applicable. Ceramic frits shall be as specified on the engineering drawing. Materials supplied shall meet all the requirements listed in those specifications. 3.13.3.3 Ceramic Frit Thickness (ASTM B 487, Non-Metallic Substrates) Coating thickness must be suffici

38、ent to meet all requirements of this material specification. Refer to mutually agreed upon control plan. 3.13.3.4 Ceramic Frit Adhesion Grade 2 max (WSS-M99P6-C1/C2) Adhesion (FLTM BI 106-01, Method B, new knife only), part should be tested in the coating ink/paint configuration as specified on the

Tolerances shall be as specified in the material specifications or on the engineering drawing. 3.14.1 Vinyl Adhesion Pu

40、mmel Test Pummel value 3-6 (Pummel Adhesion Procedure FLTM BU 158-01) This test is conducted to determine the bond between the glass and the vinyl on laminated products. This test is typically used for process control within each plant. Additionally, laminated products with any coating on either of

41、the two inner surfaces must maintain a pummel adhesion value between 3 and 6 after being exposed to the weathering conditions of section 3.16. ENGINEERING MATERIAL SPECIFICATION WSS-M28P1-B1/B7 Copyright 2018, Ford Global Technologies, LLC Page 10 of 23 3.14.2 Bake Test The Bake test is a check for

42、laminate de-airing and moisture content, that if not within correct limits, may lead to in service bubble formation within the PVB or “ice crystal” formation. Acoustic PVB is more susceptible to this failure mode than normal PVB. Bake testing is considered a non-destructive test that should not be p

43、erformed prior to 48 hours after the initial autoclave process to allow the parts to normalize. This test is to be conducted on a full laminated part for initial qualification and shall be tested as specified in the control plan and includes all parts up to and including the PPAP phases. The bake te

44、st shall be repeated for glass thickness changes, glass bending changes, lamination process changes, manufacturing line changes, and PVB changes or as determined by Engineering/STA. Bake parts for 2hrs at 100 C and then inspect for bubbles per the most current version of the ANSI Z26.1. Parts to be

45、tested may be cut to fit the test chamber as long as the entire laminated part is tested. Bake Test inspection criteria (reference section 5.5). Any parts not meeting the ANSI Z26 specification are considered failed and the lamination process must be revised and revalidated by this test. An alternat

46、ive is to autoclave bake test the parts at ambient pressure (14 psi / 96 kPa). A stair step bake test must be performed on an initial qualification part (1 part) and when process parameters are varied from the initial validation. The stair step bake test consists of baking the same part at 110 C, 12

47、0 C, 130 C, 140 C, and 150 C and inspecting for bubbles as above after each bake cycle (each bake cycle is 2 hours). The data is to be recorded for future reference. Any bubble formation at 110 C or above is not considered a failure but should be used to alert the manufacturer to make process change

48、s to improve the de-airing of the lamination. 3.15 ADHESIVE BONDING It is the Tier 1 glass suppliers responsibility to insure that the glass, plastic surfaces and/or ceramic coatings to be adhesively bonded meet all requirements of the following applicable specifications (most current versions). Adh

49、esion testing may be performed by the glass bonding adhesive supplier on behalf of the Tier 1. Testing must be performed on the glass surface intended for bonding (specific ceramic frit, air or tin side of glass) and must be performed with the specific Ford production glass cleaners, primers, and urethanes approved in each region of use. The adhesion system used by each Ford plant receiving the Tier 1 glass must be tested. This does not rep
