ASTM C1197 – Standard Test Method for In Situ Measurement of Masonry Deformability Properties Using the Flatjack Method
This test method describes an in situ method for determining the deformation properties of existing unreinforced solid-unit masonry.
This test method concerns the measurement of in-situ masonry deformability properties in existing masonry by use of thin, bladder-like flatjack devices that are installed in cut mortar joints in the masonry wall.
This test method provides a relatively non-destructive means of determining masonry properties.
