1.1 This test method covers the following procedures for determining the structural properties of segments of floor and roof constructions:

1.2 This test method serves to evaluate the performance of floors and roofs panels subjected to (1) Uniform loading, and (2) Concentrated static loading, which represent conditions sustained in the actual performance of the element. The standard is not intended for the evaluation of individual structural framing or supporting members (floor joist, rafters, and trusses), or both.

1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of the standard.

1.4 This standard is not intended to cover concrete floor slabs.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.

4.1 Transverse Load—The procedures outlined will serve to evaluate the performance of floor and roof segments for deflection, permanent set and ultimate capacity. Performance criteria based on data from these procedures can ensure structural adequacy and effective service.

4.2 Concentrated Load—This concentrated load test shall be used to evaluate surface indentation of structural framing members.

4.3 These procedures will serve to evaluate performance of roof and floor segments under simulated service conditions. Diaphragm shear loading of roof and floor segments shall be evaluated under Test Method E455. Impact loading shall be evaluated under Test Methods E661 or E695.
