SCOPE The materials defined by this specification are automotive quality carpet assemblies, for floor, door trim, seat backs (front and any rear seat
3、 backs in exposed load compartment applications) and exposed load floors whether molded or otherwise fabricated. 2. APPLICATION This specification was released originally for passenger compartment floor coverings and other automotive trim applications. 3. REQUIREMENTS Material specification requirem
4、ents are to be used for initial qualification of materials. In addition to the requirements 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. Heel pads, w
5、hen required, shall meet the requirements of WSS-M15P37-B. 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.4 SAMPLE SELECTION All evaluations shall be conducted on
6、 test specimens taken from production representative carpet assemblies. If the specimen is taken from an area in the carpet with padding, the padding should be stripped away as much as possible before evaluation, unless otherwise specified. Test specimens for strength or abrasion properties shall be
7、 taken from molded or stressed areas of the carpet assembly (i.e., the footwell unless otherwise specified). 3.5 APPEARANCE (FLTM BI 109-01) The color, pattern, and finish shall match the approved Design Center master sample, or shall be as specified on the engineering drawing. 3.6 WEIGHT (FLTM BN 1
8、06-01) The weight shall be as specified in the individual materials specification or as designated on the engineering drawing.

9、l be as specified on the material specification and applicable engineering drawing describing the specific carpet. The padding shall be as specified on the engineering drawing and the individual padding specification. Backcoating: The backcoating shall form a continuous and uniform coating over the
10、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 required within the specification and during normal field conditions. The backcoat shall thoroughly saturate the base of the pile fiber bundles to
11、ensure adequate fiber lock. Penetration of the backcoat through to the face of the carpet shall be controlled to provide the required resistance to abrasion and fiber loss, but backcoat shall not be visible on the face of the pile fiber. Adhesion: The carpet material and padding shall be properly bo
12、nded together with the backcoating and/or adhesive where necessary, to ensure that the various components of the finished carpet assembly do not delaminate under normal handling and shipping operations. Secondary Backing Fabrics (if applicable): The secondary fabric shall be uniformly and continuous
13、ly bonded across the entire carpet and shall be free of voids and tears. 3.8 REQUIRED FOR ONGOING PRODUCTION VERIFICATION In addition to the following minimum requirements, production carpet assemblies must withstand normal handling during shipping and installation, without tearing. 3.8.1 Breaking S
