This specification describes the requirements of expanded closed-cell materials to be used as a seal against air and or dust only. These materials may also be used for silencing squeak and rattles, covering gaps and other non-sealing applications. (For sealing against water use GM6086M).

Material Identification. Materials shall be identified according to ranges of compression deflection, per section 3.2, as listed below:

• Type IAA < 5.00 kPa

• Type IA 5.00 to 21.00 kPa

• Type IB 21.01 to 48.00 kPa

• Type II 48.01 to 97.00 kPa

• Type IIIA 97.01 to 172.00 kPa

• Type IIIB 172.01 to 276.00 kPa

Certain applications may require the use of an adhesive. If an adhesive is required, an ADH suffix shall be added after the basic specification and type number.

Other interior parts will require a low friction coating to reduce friction between the seal and the substrate. When this coating is required a CO suffix shall be added after the specification.
