2、D FOR NEW DESIGN 1. SCOPE This specification defines the minimum durability and performance requirements of exterior molded in color plastic components. 2. APPLICATION This specification was released originally for exterior unpainted molded in color plastic components used in exterior subsystems inc

3、luding outside rearview mirror (OSRVM), cowl grilles and leaf screens (COWLVENT), exterior lighting (EXTLGT), bumpers (BUMPER), radiator grilles (RADGRL), door handles (DRLT), wipers (WIPER) and exterior ornamentation (EXTORN). All painted exterior components shall meet the requirements of WSS-M2P18

4、0-B for rigid substrates, WSS-M2P181-B for flexible substrates and WSS-M1P83-B2 for chrome plated rigid substrates. When specific properties of a coated substrate are not covered by these referenced performance specifications, test methods within this specification may be applied. 3. REQUIREMENTS Ma

5、terial specification requirements are to be used for initial qualification of materials. 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). This specification is based

6、on virgin material only. The use of in-house regrind is not allowed unless the part is validated during PV testing with the documented level of regrind noted on the part drawing. 3.2 FINISHED PARTS Testing must be done on actual production parts or a section of the part whenever possible. Where part

7、 dimensions limit equipment access, representative panels or plaques may be substituted for production parts. 3.3 APPEARANCE (FLTM BI 109-01) The color, gloss, and finish shall match the approved Design Center master sample or shall be as specified on the engineering drawing. 3.4 PAINT REPAIR OVEN M

8、aterials used in all systems shall withstand a paint repair surface temperature of 115 C for 20 minutes without deformation, functional damage or loss of appearance or other specified physical characteristics. If material cannot meet this requirement it must be capable of being protected, e.g., with

9、 shielding, during repair oven processing of the vehicle. ENGINEERING MATERIAL SPECIFICATIONWSS-M98P13-A Printed copies are uncontrolled Copyright 2008, Ford Global Technologies, LLC Page 2 of 4 3.5 HEAT AGING All parts shall be complete including all components packaged in the assembly (eg. mirror

10、glass and back, motor, etc. packaged into mirror shell and structure) and fastened onto actual or representative production support foundations that include not only all attaching points but also any boundary conditions that may restrict movement, unless otherwise specified by the affected Materials

11、 Engineering Activity. The retention methods, attachments and supporting moldings shall be the same as proposed for production. The heat aged part shall show no changes in appearance when compared with the original untested part. Gaps, margins and surface waviness must be within original vehicle des

12、ign tolerances after returning to ambient temperature. Test Procedure: The assembly and support foundation shall be placed in a mechanical convection oven maintained at 80+/- 2 C for 7 days. Evaluate after conditioning back to 23 +/- 2 C. 3.6 ENVIRONMENTAL TESTING (FLTM BQ 104-07, Procedure 1) All p

13、arts shall be complete including all components packaged in the assembly (eg. mirror glass and back, motor, etc. packaged into mirror shell and structure) and fastened onto actual or representative production support foundations that include not only all attaching points but also any boundary condit

14、ions that may restrict movement, unless otherwise specified by the affected Materials Engineering Activity. The retention methods, attachments and supporting moldings shall be the same as proposed for production. The cycled part shall show no changes in appearance when compared with the original unt

15、ested part. Gaps, margins and surface waviness must be within original vehicle design tolerances after returning to ambient temperature. Test Procedure All exterior subsystems will use 3 cycles of FLTM BQ 104-07 Procedure 1. 3.7 RESISTANCE PROPERTIES 3.7.1 Resistance to Cold Impact (Similar to FLTM

16、BO 151-01, Method B with 225g steel ball and 600mm drop) The impacted part shall show no evidence of cracking or breaking and shall fully recover from indentation in the time required for the assembly to return to 23 C. Test Procedure After conditioning as per FLTM BO 151-01, Method A steps 1 and 2

17、the finished part shall be mounted in a suitable device or buck simulating in vehicle position and surroundings and maintained at -40 +/- 1 C for 24 h. The impact shall be carried out on areas regarded as most vulnerable in respect of shape and installation on the vehicle and shall be indicated by t

18、he design responsible engineer and documented in the DVP. Components such as body-side moldings may be rotated 90 to simulate horizontal impact.
