ASTM E2568 Standard Specification for PB Exterior Insulation and Finish Systems
ASTM E2568 外墙外保温及饰面系统规格

This specification covers PB Exterior Insulation and Finish Systems (EIFS) defined as an exterior, non-bearing wall covering providing a weather-resistant exterior wall envelope on walls required to be combustible or noncombustible, fireresistance-rated or nonfire-resistance-rated. Further, PB EIFS is a system described as being applied over insulation board, an adhesive or mechanical attachment of the insulation board to a substrate, or both, glass fiber reinforcing mesh, a base coat on the face of the insulation board, and a textured protective finish coat. The following tests shall be performed in accordance to the following test methods: accelerated weathering; freeze/thaw; salt spray resistance; tensile bond adhesion; water penetration; water resistance; physical properties and requirements for EPS; alkali resistance of reinforcing mesh; fire endurance; full-scale multi-story fire test; and ignition resistance.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope
1.1 This specification covers PB Exterior Insulation and Finish Systems (EIFS) defined as an exterior, non-bearing wall covering providing a weather-resistant exterior wall envelope on walls required to be combustible or noncombustible, fire-resistance-rated or nonfire-resistance-rated. Further, PB EIFS is a system described as being applied over expanded polystyrene or polyisocyanurate insulation board, an adhesive or mechanical attachment of the insulation board to a substrate, or both, glass fiber reinforcing mesh, a base coat on the face of the insulation board, and a textured protective finish coat.
1.2 This specification does not cover Class PB EIFS with drainage.
1.3 This specification qualifies EIFS products for use in normal service conditions and is not for evaluating in service EIFS installations.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
