1 Scope

This specification describes functional requirements for a sheet form material (flexible, soft) used inside the vehicle door as a barrier to water, air, dust and noise intrusion. Types I and II provide an effective barrier to noise when openings are kept small or are sealed. Materials must function in continuous operat-ing temperatures from -29 to 121 C with expected in-termittent exposure to automotive industry paint repair cycles. These materials will not stain fabric surfaces. All four types are normally supplied with adhesive on one side and a release surface on the opposite side, so that they may be stacked for shipping. They may be flat, or may be vacuum-formed to fit the shape of door components.
