9、age 2 of 4 3.3 APPROVED SOURCES This specification is performance based and does not have approved sources. 3.4 CLEAR PROTECTIVE COATINGS All clear protective coatings must use an approved source from WSS-M80J6-latest / WSS-M16J18-latest. Surrogate data from WSS-M80J6-A or WSS-M16J18-A is acceptable
10、, however, if not using an approved source, para 3.4.1 must be performed. Applicable to parts using materials without previous weathering approval. 3.4.1 Accelerated Weathering Resistance Defer to appropriate UV Cure (WSS-M80J6-A para 3.8.3) or Thermal Cure (WSS-M16J18-A para 3.8.3). Yellowness Inde
11、x (YI), Haze, and Adhesion is required. 3.5 CLEAR COATED LENS Unless otherwise indicated, the following testing must be done on the coated lens. Clear coated parts shall be aged 16 h at 45 +/- 2 C or 72 h at 23 +/- 2 C followed by a minimum of 24 h at 23 +/- 2 C and 50 +/- 5% relative humidity prior
12、 to test (unless otherwise noted). Testing must be conducted per Table 1.0, unless otherwise agreed to by Ford Materials Engineering. 3.5.1 Baseline Adhesion 4b or better (ASTM D 3359, Method B, 13 cm2 of 3M 898-2 tape) Lightly hand sand clear coat surface (10 double rubs, moderate pressure) with P6
13、00 Paper until dull, before scribe operation and checking adhesion. 3.5.2 Adhesion After SDS Testing (Para 3.2 Only *) 4b or better (ASTM D 3359, Method B, 13 cm2 of 3M 898-2 tape) *Test after relevant SDS testing (on assembly is acceptable). Lightly hand sand paint film surface (10 double rubs, mod
14、erate pressure) with P600 Paper until dull, before scribe operation and checking adhesion. 3.5.3 Film Thickness Report (ASTM B 487) 3.5.4 High Performance Coating Adhesion 3.5.4.1 Thermal Shock Test for Coating Adhesion Rating 19 min (FLTM BI 107-05) Or Alternate Method 3.5.4.2 Resistance Against Hi
15、gh Pressure Cleaner 2 mm2 max (FLTM BO 160-04, Method B) Prior to testing the painted surface shall be X-scribed through to the substrate (30 angle). The test must be performed on the X-scribe.
