1. Scope*
1.1 This specification covers solid precast segmental con-
crete masonry units made from hydraulic cement, water, and
suitable mineral aggregates, with or without the inclusion of
other materials. The units are intended for use in the construc-
tion of catch basins and manholes.
1.2 The text of this standard referenced notes and footnotes
that provide explanatory material. These notes and footnotes
(excluding those in tables and figures) shall not be considered
as requirements of the standard.
1.3 The values stated in inch-pound units are to be regarded
as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only
and are not considered standard.
1.4 This international standard was developed in accor-
dance with internationally recognized principles on standard-
ization established in the Decision on Principles for the
Development of International Standards, Guides and Recom-
mendations issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.
