【国外标准】 Standard Test Method for Shear Bond Strength of Adhered Dimension Stone

4.1 This test method provides a quantitative means of determining the shear bond strength between an installed adhered stone and its substrate. This test can be used as a means of determining the shear bond strength of pre-existing or recently installed stone assemblies.4.2 The maximum stone specimen size is 6 by 6 in. [150 by 150 mm]. The size limitation is provided to establish a practical specimen size, limit maximum breaking load, and prevent out-of-plane stress.1.1 This test method is used for determining the shear bond strength of dimension stone wall or floor assembly adhered to a substrate.1.2 This test method was developed for adhered stone applications and may be used in a laboratory or in the field.1.3 Testing is performed on cured stone assemblies on a vertical or horizontal plane in an interior or exterior application. Load is applied to one edge of the stone. The load is applied at a specified rate until the stone assembly fails.1.4 The values stated in either inch-pound units or SI 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.1.5 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.
