1.1本规程涵盖了现场或预制应用PB级外部绝缘和饰面系统（EIF）的最低要求和程序。PB类EIF定义为应用于各种类型绝缘板上的系统，其中底漆范围不小于1/16英寸。（1.6毫米）至1/4英寸。（6.4 mm），取决于封装在底漆中的非金属钢筋网层的数量。然后用各种纹理和颜色的不同厚度的面漆覆盖底涂层。 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This practice covers the minimum requirements and procedures for field or prefabricated appliation of Class PB Exterior Insulation and Finish Systems (EIFS). Class PB EIFS are defined as systems applied over various types of insulation board, in which the base coat ranges from not less than 1/16 in. (1.6 mm) to 1/4 in. (6.4 mm) in dry thickness, depending upon the number of nonmetallic reinforcing mesh layers encapsulated in the base coat. The base coat is then covered with a finish coat of various thickness in a variety of textures and colors. This standard does not purport to address all of the safety problems, 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.
