SCOPE This specification defines the standardized characteristics required for package tray assemblies with carpeted, woven/knitted, painted or other decorative surfaces. 2. APPLICATION This specification was released orig

3、inally for performance requirements for rear package trays. Limitation: Foam is not allowed for use in visible areas due to UV stability issues (degradation). 3.

9、ge 2 of 12 The color and face construction shall match the approved Design Center master sample, or shall be as specified on the engineering drawing. 3.4 COMPOSITION AND CONSTRUCTION The face material shall be as specified on the material specification and/ or the Engineering Drawings. The substrate

10、 composition shall be as specified on the Engineering Drawing and/or the Material Specification as required. Backcoating (If applicable): The back coating shall form a continuous and uniform coating over the back of the face material so that the entire backing of the face material is covered. Also,

11、the backcoat shall show no evidenced of cracking or crumbling during any of the evaluations required within the specification and during normal field conditions. The backcoating shall thoroughly saturate the base of the fibers to ensure adequate fiber lock. Penetration of the backcoat through to the

12、 face of the material shall be controlled to provide the required resistance to abrasion and fiber loss, but the backcoat shall not be visible on the face of the material. Adhesion: The face material and substrate shall be properly bonded together with the backcoating and/or adhesive where necessary

13、, to ensure that the various components of the finished package tray assembly does not delaminate under normal handling and shipping operations. 3.5 ASSEMBLY TESTING 3.5.1 Short Term Heat, Humidity and Cold Cycle (ISO 105-A02/ AATCC Evaluation Procedure 1) Conduct then test with the trim assembly mo

14、unted on an actual or simulated production support foundation with the approved retention methods. In order to test the effects of temperature fluctuations combined with humidity (so called “thermal fatigue”) the composite is subjected to the following cyclic loading: 5 h at -30 +/- 2 C 30 minutes a

15、t 23 +/- 2 C and 50% R.H. 5 h at 100 +/- 2 C 30 minutes at 23 +/- 2 C and 50% R.H. 2 h at 50 +/- 2 C and 95 +/- 5% R.H. 30 minutes at 23 +/- 2 C and 50% R.H. 5 h at -30 +/- 2 C 30 minutes at 23 +/- 2 C and 50% R.H. 5 h at 100 +/- 2 C Requirements: The trimmed assembly, after the test, shall exhibit

16、no visible and objectionable appearance such as: wrinkling, distortion, blistering, delamination, blushing, hazing, or milking of the decorative surface, or expansion, shrinkage, or warpage which will interfere with normal functional operation. . The trimmed assembly shall not exhibit movement in ex

17、cess of 3.0 mm at the specified points. These points shall be determined in agreement with PD Engineering prior to testing. Parts must be measured before testing, at greatest movement during exposure and after exposure. Measurements can be taken at the end of every cycle. If measurements are taken a

18、llow an additional 30 minutes to take measurements and to allow the chamber to stabilize prior to the next cycle. Measure and record the gap at ENGINEERING MATERIAL SPECIFICATION WSS-M15P6-E Copyright 2015 Ford Global Technologies, LLC Page 3 of 12 specified points. Also report the difference from t

19、he original gap measurement. Test report to include sketch of part with the measurement points indicated. 3.5.2 Long Term Heat Aging Rating 4 min (7 days at 100 +/- 2 C, ISO 105-A02 / AATCC Evaluation Procedure 1) The trimmed assemblies shall remain relatively unaffected by the exposure cycles durin

20、g and after the tests as demonstrated: The cover materials and scrim shall show no evidence of tackiness, exhibit a color tone change or exhibit fiber deterioration. Any “spotty“ or non-uniform staining or discoloration shall be cause for rejection. The cover materials and scrim shall not delaminate

21、 or bridge from substrate after exposure. Functionally no excessive expansion, shrinking or warping that will interfere with normal functional operations is allowed. Dimensionally the trimmed assembly shall not exhibit movement in excess of 3.0 mm at the specified points. These points shall be deter

22、mined in agreement with PD Engineering prior to testing. 3.5.3 Impact Test Method: (Gardner Instruments Impact Tester or equivalent).

23、ter, test at the noted force below. 23 +/- 2 C 5.0 J The assembly shall show no evidence of cracking or breaking and shall fully recover from indentation in the time required for the assembly to recover to 23 +/- 2 C. 3.5.4 Droop (supported package trays only) 100 mm max Test Method: Extend 1/2 the

24、length, longest dimension, of a finished part, trim side up, over the end of a suitable flat surface. After one minute, measure the maximum amount of deflection, relative to the flat surface, of the unsupported end of the part. 3.5.5 Sag 12 mm max Test Method: Mount package tray in a production repr
