Standard Test Methods for Flexural Bond Strength of Masonry
1.1These test methods cover determination of the flexural bond strength of unreinforced masonry assemblages. Two procedures are provided:
1.1.1Test Method A - Simply supported beam with third-point loading.
1.1.2Test Method B - Simply supported beam with uniform loading.
Note 1:Third-point loading (Test Method A) produces a moment distribution that is significantly different from uniformly distributed loading (Test Method B).Third-point loading (Test Method A) subjects more mortar joints to the maximum moment and thus, is likely to produce more conservative capacities than uniform loading (Test Method B).
1.2The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
1.3These test methods cover the application of the tests using either inch-pound or SI units. The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
1.4This 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.
1.5This 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.
