These test methods cover two compression tests of masonry prisms:

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.

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.

This method covers procedures for obtaining representative samples of fresh cement grout as delivered to or mixed at the project site on which tests are to be performed to determine compliance with quality requirements of the specifications under which the grout is made available.
