    2、echnologies, LLC Page 1 of 16 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 otherwise f

    3、abricated. 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 with c

    4、aution on second and third row seats. Potential concerns may arise with fiber snagging and pilling. Use only in areas with limited customer interactions. Vacuumability of non-wovens is difficult due to the construction, pet hair, debris can become entrapped in the loops of the non woven construction

    5、. Vacuumability can be significantly improved by switching to a tufted product. 3. REQUIREMENTS 3.1 APPROVED SOURCES This specification is performance based and does not have approved sources. 3.2 CONDITIONING AND TEST CONDITIONS All test values are based on material conditioned for not less than 24

    6、 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 PERFORMANCE CRITERIA 3.3.1 In addition to the requirements listed herein, the individual carpet assembly comp

    7、onents 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. Material specification requirements are to be used for initial qualification of mate

    8、rials. 3.3.2 Insulation materials shall meet the requirements of WSS-M99P32-D1/latest. Mold in Color plastic components shall meet the requirements of WSS-M15P4-G/latest. Toe pads/foot rest covers shall meet the requirements of WSS-M15P37-C1/latest. 3.4 SAMPLE SELECTION See Table 1 and 2 for sample

    9、size and testing requirements. When production test specimens are taken from an area in the carpet with padding, the padding should be stripped away as much ENGINEERING MATERIAL SPECIFICATION WSS-M8P16-B Copyright 2017, Ford Global Technologies, LLC Page 2 of 16 as possible before evaluation, unless

    10、 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 roll stock will be reviewed for initial approval. Final approval will

    11、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. 3.5 APPEARANCE The color, pattern, and finish shall match the approved Design Center master sample. 3.6 WEIGHT (FLTM BN 106-01) The weight shall be as

    12、 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 supplier shall calculate the total fiber weight after subtracting the actual weight of the primary backing for each batc

    13、h and shall not use the nominal value. 3.7 COMPOSITION AND CONSTRUCTION Shall be as specified on the Material Specification. The Floor Carpet Supplement Form shall be completed and submitted to Materials Engineering with the construction package. Backcoating: The backcoating shall form a continuous

    14、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 required within the specification and during normal field conditions. The backcoat shall thoroughly saturate the base

    15、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 abrasion and fiber loss, but backcoat shall not be visible on the face of the pile fiber. If the carpet does not have a bac

    16、k coating it shall be a fused backed carpet. 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 delaminate under normal handling and shipping

    17、operations. Adhesion properties must meet requirements in WSS-M99P32-D1/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 and tears. 3.8 PHYSICAL PROPERTIES In

    18、 addition to the following minimum requirements, production carpet assemblies must withstand normal handling during shipping and installation, without tearing. For additional information refer to Section 3.7. 3.8.1 Breaking Strength (ASTM D 5034 Grab Method, 305 mm/minute jaw speed) Floor Other Trim
