Note: Nothing in this standard supercedes applicable laws and regulations.

Note: In the event of conflict between the English and domestic language, the English language shall take precedence.

Purpose. This standard covers the requirements of dense elastomeric rubber seals attached to a solid carrier used in sealing body openings.

Material Description. The bulb or sealing portion of the weatherstrips shall be made from ethylene propylene diene monomer (EPDM) or thermoplastic elastomer (TPE). The specifications for the carrier shall be specified on the engineering part drawing or in the math data file.

Weatherstrip assemblies shall consist of continuous extruded sections or sections joined together. These sections shall be joined by either transfer or injection molded joints, or mitered joints securely attached with suitable adhesive. Joint offsets in visible and sealed areas shall be less than 0.25 mm.

Coatings. When applied, coatings shall be non-abrasive and uniform in color, finish, and texture. Coatings must meet the requirements of color and gloss as established by GM Appearance Engineering.

Applicability. Typical applications include: sealing profiles in the body area, e.g., rocker seals, cutline seals.
