Purpose/Material Description.

This specification sets forth requirements for weatherable, flexible material suitable for exterior accessory applications. The material shall fit one of two classes, plastic roll goods (PRG) or textile fabric. The material shall be resistant to tearing, permanent creasing, and mildew or fungal attack. The material shall not be permeable to water, save for vehicle cover applications. The requirements in this specification are defined relative the part commodity for which the material shall be used; types to include:

• Type B:

Bimini Tops

• Type F:

Front End, Grille, and Aero Protection

• Type S:

Spare Tire Covers

• Type T:

Tonneau Covers

• Type V:

Class P, Plastic Roll Good.

The material shall consist of a synthetic polymer face, such as Polyvinyl Chloride (PVC), Thermoplastic Olefin (TPO) or Polyurethane (PUR), supported by a textile fabric. The material may include additional layers.

Class F, Fabric.

The material shall consist of a textile fabric face supported by an inner polymer layer for waterproofing. It may include additional layers.

Class O, Other Fabric.

The material shall consist of a textile fabric face not supported by any other layer.

Symbols.

The finish symbol code defines the material construction and will be assigned by the responsible department. Trim materials are described by finish symbols which define commodity type, face material class, face material chemistry, and construction sequence number. The construction code is a unique identifier of the technology used to make a specific product. The construction code is described in detail on the completed Exterior Accessory Textile Construction Specification Form, CG6375.

Applicability.

This standard applies to exterior accessory materials only. It does not apply to multi-layer fabric with an inter rubber layer, as used for convertible soft tops. Refer to GMW16686 for that type of material.
