【国外标准】 Standard Guide for Specifying and Testing Field-Constructed Exterior Building Wall System Mockups in New Construction

4.1 This guide is intended to assist the construction team in evaluating the constructability, functionality, sequence of construction, interference, tolerances, component performance, and assembled system performance of the exterior wall systems.4.2 This guide does not establish specific roles for the parties involved during construction or the contractual obligations of those parties. The role of each party within any specific project should be established and documented before the start of the project.4.3 This guide is intended for use when specifying construction mockups that are either integrated mockups or off-structure mockups.4.4 This guide is intended to aid the specifier in the development of a QA mockup program for assessing the performance of exterior walls. It is not intended to provide a comprehensive list of applicable test methods for QA testing available or applicable to a mockup program.4.5 This guide does not address preconstruction laboratory testing of a wall system.4.6 This guide is intended to address technical issues with the performance of the wall system and the interconnection of the various components and systems. A mockup may or may not be used as an aesthetic mockup; however, this guide is not intended to address aesthetic issues with the wall system.4.7 This guide is not intended to provide guidance for construction observation services. However, the mockup may be useful to inform inspectors of the intended construction, sequence, materials, and interface conditions encountered on the project and serve as a standard of quality to which the remainder of construction can be compared.1.1 This 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.1.2 This 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.1.3 This 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.1.4 This 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.1.5 The 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.1.6 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.1.7 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.
