ASTM E835/E835M-93(1999)

Standard Guide for Modular Coordination of Clay and Concrete Masonry Units

SCOPE
1.1 This guide covers unit sizes for clay and concrete masonry units laid in mortar for use in buildings and building systems designed in accordance with the principles of modular coordination. Specifically it covers:
1.1.1 Sizes of full-size units and supplementary units.
1.1.2 Joint thicknesses.
1.1.3 Specified dimensions.
1.2 Permissible variations from specified dimensions of masonry units vary with intended use, project requirements and type of product. Thus, permissible dimensional variations for masonry units should be obtained from the appropriate ASTM specification. See Section 2 for a listing of appropriate specifications.

Standard Guide for
Modular Coordination of Clay and Concrete Masonry Units
This standard is issued under the fixed designation E 835/E 835M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.
A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
INTRODUCTION
This guide is issued as a standard for reference in design, specification, manufacture and
construction using metric (SI) or inch-pound units. The SI preferred dimensions are based on the
internationally recognized building module of 100 mm. The inch-pound preferred dimensions are
based on the U.S. recognized building module of 4 inches. Dimensions given in millimeters (mm)
apply to units designed for SI use. Dimensions given in inches (in.) apply to units designed for
inch-pound use.
This guide is intended to minimize the potential field cutting of units due to the layout requirements
of the construction and contract documents. It is not the intent of this guide to restrict or limit the
production of units not conforming to modular dimensional coordination.
