(Test Method)Standard Test Methods for Evaluating Water-Resistive Barrier (WRB) Coatings Used under Exterior Insulation and Finish Systems (EIFS) or EIFS with Drainage
Standard Test Methods for Evaluating Water-Resistive Barrier (WRB) Coatings Used under Exterior Insulation and Finish Systems (EIFS) or EIFS with Drainage
SIGNIFICANCE AND USE
4.1 This series of test methods provides a means to evaluate performance of the water-resistive barrier coating when subjected to various physical and environmental conditions. The water-resistive barrier coating is applied between the EIFS and substrate in an EIFS-clad wall assembly and is intended to provide additional protection to the building and its contents from incidental moisture intrusion that may occur through the building envelope. Although protected from direct weather exposure after the EIFS is installed, the coating must be durable and weather resistant as it is subjected to various environmental conditions prior to application of the EIFS as well as while the system is in service.
SCOPE
1.1 These test methods apply to trowel, roller, or spray applied Water-resistive barrier (WRB) coatings that are applied over exterior sheathing prior to application of EIFS or EIFS with drainage wall claddings.
1.2 Test methods for in place wall system and cladding related to tests such as fire resistance, wind load capability, air barrier performance, and so forth. should also be considered but are outside the scope of this document.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
