Fog evaluation
9、 is visual. Microscopic evaluation is used only for further evaluation of oily droplets or crystals. Sample shall be tested as an assembly if it is 100% bonded. If not 100% bonded, test each component separately. 3.5 ODOR Rating 3 max (FLTM BO 131-03) Sample shall be tested as part of a production a
10、ssembly composite if it is 100% bonded. If not 100% bonded, test each component separately. 3.6 FLAMMABILITY (ISO 3795) Burn Rate 100 mm/minute max Sample shall be tested as part of a production assembly composite if it is 100% bonded. If not 100% bonded, test each component separately. 3.7 CONSTRUC
11、TION PROPERTIES 3.7.1 Bond Strength (applicable to welded or sewn seams) 3.7.1.1 Original 50 N min 3.7.1.2 After Environmental Cycling 75% min of original In para 3.9. value Test Method: Specimens 15 mm in width and approx. 150 mm in length shall be cut across the bond line and then clamped in the j
12、aws of a tensile machine such that the bond line is centered between the jaws. The maximum breaking strength will be determined using a test speed of 500 mm/min. Report the average of all specimens tested. 3.7.2 Resistance to Mildew (7 days at 98 +/- 2 % relative humidity and 38 +/-2 C.) Test Method
13、 Cut specimens from the thickest section. Specimen size is 200 x 200 mm unless part size is smaller. Expose for 7 days in a humidity cabinet. Evaluation Remove the part from the cabinet and evaluate immediately. The part shall exhibit no visible evidence of mildew growth and/or objectionable odor af
14、ter 7 days exposure.

15、Method: Install a complete sun visor using production assembly techniques, in an approved test fixture or vehicle buck representative of intended production dimensions. Expose the vehicle (with windows open) or test buck to the following environmental cycle one time. After completion, condition the
16、part for 24 h minimum at standard atmosphere of 23 +/- 2 C and 50% R.H prior to examination. Ramp speed 1 to 5 C per minute (record actual ramp speed on data sheet). . 5 h at -30 +/- 2 C . 30 min at 23 +/- 2 C and 50% R.H. . 5 h at 90 +/- 2 C . 30 min at 23 +/- 2 C and 50% R.H. . 16 h at 50 +/- 2 C
17、and 95 +/- 5% R.H. . 30 min at 23 +/- 2 C and 50% R.H. . 5 h at -30 +/- 2 C . 30 min at 23 +/- 2 C and 50% R.H. . 5 h at 90 +/- 2 C Note: The sequence does not include ramp times between each condition. Depending on the equipment and fixtures each transition period may vary in length of time. Total
18、test time will exceed 38 hours due to the time ramp times. Acceptance Criteria: The part shall not show any color change, change in gloss or tackiness. Furthermore, no wrinkles, delamination, cracking, bond line failures, or loss in part functionality are permitted. If present, the mirror shall not
19、show any distortion. 4. GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements of this specification. Contact for questions concerning Engineering Material Specifications. 4.1 STORAGE AND ASSEMBLY To avoid crush marks on the face fab
20、ric, finished headliners are supplied in packaging that will protect part integrity. They should not be removed from the pallets until required for fitting to the vehicle. To prevent soiling during handling and fitting operations, the face side of the assembly may be covered by a self-adhesive polye
21、thylene film. ENGINEERING MATERIAL SPECIFICATION WSS-M98P3-C Copyright 2016, Ford Global Technologies, LLC Page 4 of 5 4.2 IDENTIFICATION MARKING The reverse side of each assembly must be marked in a suitable way to identify its production batch. There shall be no evidence of identification mark ble
22、ed through onto the cover materials surface, nor any staining of adjacent assemblies during storage. If a class A surface protective film is used no adhesive residue can remain after removal. 4.3 APPROVAL OF MATERIALS Suppliers desiring approval of their materials shall first obtain an expression of
23、 interest from Purchasing, Design or Product Development, and Materials Engineering. The supplier shall submit a completed copy of their laboratory test reports, signed by a qualified and authorized representative of the test facility, demonstrating full compliance with all the requirements of the M
24、aterial Specification. Tested material samples must be available for review upon request and kept for a minimum of one year. Upon request, the supplier will review the associated quality control documents (Process Failure Mode and Effects Analysis, Control Plans, Certification testing) with Ford. 4.
25、4 SUPPLIERS ONGOING RESPONSIBILITY All materials must be equivalent in all characteristics to the material upon which approval was originally granted. Prior to making any changes to the material originally approved, whether or not such changes affect the materials ability to meet the specification r
26、equirements, the supplier shall notify the affected Supplier Technical Assistance (STA), Purchasing, and Materials Engineering activities of the proposed changes (with reasons) by submission of a completed Suppliers Request for Engineering Approval, SREA. For parts and components using Ford Engineer
27、ing Material Specifications, all samples tested to the specifications for Design Verification (DV), Production Verification (PV) and Production Part Approval Process (PPAP) sign off must be kept until Job 1. 4.5 RESTRICTED SUBSTANCE MANAGEMENT STANDARD Substance restrictions imposed by regulations o
28、r Company direction applies to the materials addressed by this document. The restrictions are identified in the Restricted Substance Management Standard WSS-M99P9999-A1 which is updated yearly. It is the suppliers responsibility to comply with this standard on a continuing basis through IMDS and or
