本标准概述了外墙外保温和饰面系统（EIF）的要求，该系统与作为外墙覆层系统的排水空间结合使用。它还概述了可与EIF一起使用的阻水屏障系统（WRB）的要求。EIFS墙面包层系统由刚性隔热板、用于将隔热板连接至基材的粘合剂、嵌入隔热板表面底漆中的玻璃纤维加强网和面漆组成。机械紧固件的使用不在本标准的范围内，但可作为粘合剂的补充和/或替代物，用于基材不支持EIF的粘合剂连接的连接。 在EIF中，隔热板用整体玻璃纤维加强网支撑底层。本标准不包括钢筋作为抹灰支撑构件的系统，例如传统灰泥。在本版本中，为了清晰起见，对标准中的一些材料进行了重新组织。增加了评估适用于EIF的阻水屏障系统和评估EIF排水性能的额外要求。

This Standard outlines requirements for Exterior Insulation and Finish Systems (EIFS), used in combination with a drained air space as an exterior wall cladding system. It also outlines requirements for water resistive barrier systems (WRBs) that can be used with EIFS.The EIFS wall cladding system is comprised of rigid thermal insulation boards, an adhesive for attachment of the thermal insulation boards to the substrate, a glass fibre reinforcing mesh embedded in a base coat on the face of the thermal insulation boards and a finish coat.The use of mechanical fasteners is outside the scope of this Standard, but is acceptable as a complement and/or as an alternate to adhesive for attachment where the substrate will not support adhesive attachment of the EIFS.In EIFS, the thermal insulation boards support the base coat with integral glass fibre reinforcing mesh. Systems where the reinforcement is the supporting element of the rendering, e.g., conventional stucco, are not covered by this Standard.In this edition, some of the material in the standard has been reorganized for clarity. Additional requirements have been added for evaluating water resistive barrier systems that are suitable for use with EIFS and for evaluating the drainage performance of EIFS.
