Note 1 - Design and construction procedures for conventional concrete masonry construction have been written by the American Concrete Institute, "Building Code Requirements for Concrete Masonry Structures" and the National Concrete Masonry Associations, "Specification for the Design and Construction of Load-Bearing Concrete Masonry."

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
