1、 ENGINEERING MATERIAL SPECIFICATION PERFORMANCE, CARPET, FLOOR AND TRIM WSS-M8P16-B 1. SCOPE The materials defined by this specification are automotive quality carpet assemblies, for floor, door trim, seat backs in exposed load compartment applications and exposed load floors whether molded or other

2、wise fabricated. 2. APPLICATION This specification was released originally for passenger compartment floor coverings and other automotive trim applications. 2.1 LIMITATIONS The use of non woven carpets is not applicable to first row seat backs (full covering) but may be used in the toe kick area or

3、with caution on second and third row seats. Potential concerns may arise with fiber snagging and pilling. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements for Production materials (WSS-M99P1111

4、-A). 3.1.1 Vehicle Interior Environment Quality Materials/Component Performance Requirements Materials used in interior applications must meet the requirements outlined in WSS-M99P2222-D1. Data for the component shall be performed at the appropriate program milestone. 3.1.2 In addition to the requir

5、ements listed herein, the individual carpet assembly components shall meet all the requirements of the applicable material specifications for the carpet, padding, adhesive, barrier, or trim application as well as any functional/SDS requirements as outlined by Engineering. 3.1.3 Heel pads, when requi

6、red, shall meet the requirements of WSS-M15P37-B. Insulation materials shall meet the requirements of WSS-M99P32-C/latest. 3.2 SAMPLE SELECTION See Table 1 and 2 for sample size and testing requirements. When production test specimens are taken from an area in the carpet with padding, the padding sh

7、ould be stripped away as much as possible before evaluation, unless otherwise specified. For floor carpet applications, test specimens for strength and abrasion properties shall be taken from molded or stressed areas of the carpet assembly, i.e. the front footwell unless otherwise specified. The rol

8、l stock will be reviewed for initial approval. Final approval will be granted on a program by program basis on the molded product once the specification testing is reviewed and signed off on by Materials Engineering.

10、master sample, or shall be as specified on the Engineering Drawing. 3.4 WEIGHT (FLTM BN 106-01) The weight shall be as specified in the individual material specification and Floor Carpet Construction Supplement. The weight per square meter is applicable to rollstock carpet. For tufted carpets the su

11、pplier shall calculate the total fiber weight after subtracting the actual weight of the primary backing for each batch and shall not use the nominal value. 3.5 COMPOSITION AND CONSTRUCTION Shall be as specified on the Material Specification The Floor Carpet Supplement Form shall be completed and su

12、bmitted to Materials Engineering with the construction package. Backcoating: The backcoating shall form a continuous and uniform coating over the back of the carpet so that all pile fibers are covered. Also, the backcoat shall show no evidence of cracking or crumbling during any of the evaluations r

13、equired within the specification and during normal field conditions. The backcoat shall thoroughly saturate the base of the pile fiber bundles to ensure adequate fiber lock. Penetration of the backcoat through to the face of the carpet shall be controlled to provide the required resistance to abrasi

14、on and fiber loss, but backcoat shall not be visible on the face of the pile fiber. Adhesion: The carpet material and substrate shall be properly bonded together with the backcoating and/or adhesive where necessary, to ensure that the various components of the finished carpet assembly do not delamin

15、ate under normal handling and shipping operations. Adhesion properties must meet requirements in WSS-M99P32-C/latest. Secondary Backing Fabrics/Heavy Layer (if applicable): The secondary fabric/heavy layer shall be uniformly and continuously bonded across the entire carpet and shall be free of voids

16、 and tears. 3.6 PHYSICAL PROPERTIES In addition to the following minimum requirements, production carpet assemblies must withstand normal handling during shipping and installation, without tearing.
