Introduction

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 for elastomeric sealing profiles, mainly used in the area with movable glass panes. These seals can be flocked or coated.

Material Description. The sealing portion of the weatherstrips shall be made from ethylene propylene diene monomer (EPDM) rubber or thermoplastic elastomer (TPE). The specifications for the carrier shall be specified on the engineering part drawing and 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. Joint offsets in visible and sealed areas must be < 0.25 mm. Visible areas of joints must be straight, with no mold to extrusion material bleed on the visible surfaces. See Appendix A, Figure A1 through Figure A6.

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 the following: sealing profiles in areas with movable glass, such as door glass run channels, insulators, and belt strips.
