ASTM C1892/C1892M-20a PDF Download

The ASTM C1892/C1892M-20a standard provides procedures for testing the tensile and shear strengths of anchors intended to be installed in masonry assemblies. These test methods aim to generate reproducible data that can be used to establish acceptance criteria, design data, and specifications for masonry anchors.

The standard addresses post-installed and placed-during-construction anchors in masonry test specimens, considering environmental exposures such as freezing and thawing, moisture, decreased and elevated temperatures, and corrosion. The testing procedures outlined in the standard are intended to be performed in a testing laboratory and serve as basic guidelines that can be tailored to the requirements of product-specific evaluation and acceptance standards. Only the tests required by the specifying authority need to be conducted.

The standard covers a range of loadings, including quasi-static, dynamic, fatigue, and shock, and emphasizes the importance of considering environmental factors in anchor testing. It also distinguishes between post-installed and placed-during-construction anchors designed for installation projecting from the surface of a masonry test specimen.

The standard provides flexibility for combined tests that incorporate multiple types of loading, such as dynamic, fatigue, and shock tests in series, but also prescribes separate procedures for static, dynamic, fatigue, and shock testing. It allows for the use of inch-pound or SI units, with anchor diameters, threads, and related testing equipment being in accordance with the chosen unit system. The values stated in each system are not necessarily equivalent, and the standard emphasizes that each system should be used independently, with values from different systems not being combined.
