1.1 These methods cover compression tests of masonry prisms. Two methods are provided:
1.1.1 Method A—For determining comparative data on the compressive strength of masonry built in the laboratory with either different masonry units or mortar types, or both.
1.1.2 Method B—For determining the compressive strength of masonry built at the job site with the same materials and workmanship to be used, or being used, in a particular structure.
1.2 Test specimens for both methods are short compression prisms; the influence of slenderness ratio is taken into account either by proportions of the fabricated specimens or by the application of a correction factor.
