Standard Practice for Specification and Evaluation of Pre-Construction Laboratory Mockups of Exterior Wall Systems

Importancia y uso:

4.1 Exterior wall systems require time to design, fabricate, construct and test. Mockups are generally a full-size representative portion of the proposed exterior wall system built to study proposed construction details, test for performance, and in some cases judge appearance of the exterior wall system. The project schedule shall allow time to design, construct, and test the pre-construction mockup and to implement any design changes, fabrication changes, or modifications of planned construction procedures, before construction of the exterior wall system commences.

4.2 Performance testing of pre-construction mockups verifies compliance with specified standards and design criteria. Performance tests in separate ASTM or other industry standards, are intended to represent the effects of environmental conditions, such as wind, rain, and temperature extremes. The tests provide a measure of the performance of the proposed exterior wall system under specific and controlled conditions. The specified design and specification of the pre-construction mockup must be appropriate for the performance test requirements. Separate tests may be required for individual mockup materials or components.

4.3 Pre-construction mockup specimens require input from Specifier, Builder, and Test Agency. Coordination of their efforts facilitates this process. Documentation should convey the results of preconstruction mockups from one party to others at appropriate stages in the process.

4.4 The referenced standards provided in this practice identify the historical standards typically utilized in pre-construction performance testing. This practice allows for the development and use of other project specific test procedures for various components that encompass exterior wall systems.
