Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEEditorial changes were made throughout to comply with ASTMs policy on Units in Standards (April 2009).1. Scope1.1 This specification covers PB Ex
3、terior Insulation andFinish Systems (EIFS) defined as an exterior, non-bearing wallcovering providing a weather-resistant exterior wall envelopeon walls required to be combustible or noncombustible, fire-resistance-rated or nonfire-resistance-rated. Further, PB EIFSis a system described as being app
4、lied over expanded polysty-rene or polyisocyanurate insulation board, an adhesive ormechanical attachment of the insulation board to a substrate, orboth, glass fiber reinforcing mesh, a base coat on the face of theinsulation board, and a textured protective finish coat.1.2 This specification does no
