1.1This guide provides information to assist in the specification, design, and performance testing of field-constructed exterior wall assemblies (“mockups”) for construction projects. This includes testing procedures appropriate to evaluate the component and assembly performance for water penetration resistance, air leakage resistance, and other test methods that may be applied as part of the quality assurance (QA) program for the installed systems.

1.2This guide is intended to be applied to exterior wall mockups that include components, systems, and assemblies including, but not limited to, curtain walls, windows, doors, masonry walls, precast concrete, cast-in-place concrete, exterior insulation and finish system (EIFS), roofing interfaces, stucco, wood siding, metal panels, sealants, appurtenances, penetrations, louvers, and combinations thereof. Such mockups are expected to include the intersection between wall systems.

1.3This guide is not intended to provide a comprehensive list of potential testing that may be applicable to field-constructed mockups. Additional tests may be applicable to mockups for specific projects.

1.4This guide is not intended to address all possible project delivery methods and as such the requirements listed herein must be evaluated by the specifier for appropriateness with the delivery method.

1.5The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

1.6This 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.

1.7This 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.
