4.3 Compression tests provide a standard method of obtaining data for research and development, quality control, acceptance or rejection under specifications, and special purposes. The tests cannot be considered significant for engineering design in applications differing widely from the load-time scale of the standard test. 1.3 This test method covers short-term axial load testing under standard indoor atmospheric conditions. It does not address: sampling, the ability of the material to carry a sustained long-term load, design load derivations, temperature effects, performance under freeze/thaw or salt spray exposure conditions, chemical/UV exposure effects, or engineering . Prior to August 2012, the compressive strength testing procedures in ASTM C140, Standard Test Methods for Sampling and Testing Concrete Masonry Units and Related Units, did not include consideration for the configuration of the tested specimen. This produced results that could vary solely due to specimen configuration.
