Significance and Use
4.1 The procedures outlined in these test methods serve to evaluate the performance of the wall segments for deflection, permanent set, and maximum load-carrying capacity under transverse loading. Performance criteria based on data collected using these procedures fall outside the scope of these test methods.
4.2 Transverse loads cannot be applied satisfactorily to some wall constructions, such as masonry, with the specimen in a horizontal position. For such constructions, the loads shall be applied to the specimen in a vertical position thus simulating service conditions.
4.3 Test results obtained from the two-point loading ( and ) and the uniform loading ( and ) are neither compatible nor interchangeable.
1.1 These test methods cover transverse load testing to determine the structural properties of wall segments.
1.2 These test methods serve to evaluate the performance of wall panels subject to transverse bending loads applied perpendicular to the plane of the wall. The tests are conducted on horizontal or vertical specimens under two-point loading. It also shall be permitted to apply uniform load using an air bag or a vacuum chamber. Depending upon the configuration tested, these loads are intended to evaluate the transverse deflection, permanent set, and maximum flexural capacity or planar shear capacity, or both, of the wall segment. These test methods are not intended for the evaluation of individual structural framing or supporting members (floor joist, decking, etc.), or both. The connections between the vertical elements of the wall segment and the surrounding construction are excluded from the scope of these methods and shall be evaluated by alternative means.
1.3 Notes and footnotes in this standard provide explanatory material. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of this standard.
1.4 The values stated in SI units are to be regarded as standard.
1.5 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.
1.6 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.
