2、 The material defined by this specification is a heat stabilized thermoplastic molding compound based on polyamide 6 resin with approximately 40% mineral filler. 2. APPLICATION This specification was released originally for material for plated interior door handles. 2.1 LIMITATIONS These materials a
3、bsorb and retain moisture. Part design and tolerances must accommodate changes in part dimensions and physical properties due to moisture absorption or loss in the service/assembly environment. This material typically does not contain UV stabilizers, long term exposure to direct sunlight will cause
4、chalking and loss of gloss and must be plated for visible interior applications. 3. REQUIREMENTS 3.1 APPROVED SOURCES This specification requires the use of approved sources. Only the sources identified on the Ford Approved Source List (ASL) can be used when this specification is listed on the drawi
5、ng, CAD file, or other documents. The list of approved sources is located within Ford at or available externally through a Ford Materials Engineer. This specification is part of the Ford Co-Managed Buy (CMB) agreement. Tier 1 molders who are participating under the CMB agreement must use one the fo
6、llowing approved sources (deviations require approval from Ford Raw Materials Purchasing and Materials Engineering): North American and European Programs: Lanxess BM240H2.0 901510 Molders not in the CMB program or regions without CMB are encouraged to use the CMB sources. 3.2 CONDITIONING AND TEST C
7、ONDITIONS All test values are based on material conditioned for not less than 24 h prior to testing in a controlled environment of 23 +/- 2 C and 50 +/- 5% relative humidity. Testing of the material should occur in the conditioning environment or soon after removal. 3.3 INFRARED SPECTROPHOTOMETRY AN
8、D/OR THERMAL ANALYSIS IR spectra and thermograms from initial material approval shall constitute the reference standard and shall be kept on file at the designated material laboratory. The material supplier shall ensure that all future material supplied to the specification shall produce IR spectra
9、and thermograms that correspond to the reference standard when tested under the same conditions.

10、011, identified certain requirements with the symbol (s), which indicated that the mean and +/- 3 sigma values were to be reported. The specification minimum, maximum or range was established using 3 sigma data. For 2011 and beyond, refer to Table 1 for number of samples required for each test. 3.4.
11、2 This specification is based on virgin material and does not allow the addition of recycled content (PIR/PCR). 3.4.3 Dry as molded: All test values indicated herein are based on material and specimens with moisture content not exceeding 0.2% except where noted (Moisture Conditioned , see paragraph
