This specification covers brick intended for use in drainage structures for the conveyance of sewage, industrial wastes, and storm water, and related structures such as manholes and catch basins. The bricks are classified as sewer bricks (Grades SS and SM) and manhole bricks (Grades MS and MM). Sewer brick shall have plain or smooth surfaces on both ends and on the face side. Manhole brick shall have plain, slightly, or moderately textured surfaces. The brick shall be sampled and tested in accordance with applicable requirements specified.

1.1 This specification covers brick intended for use in (1) drainage structures for the conveyance of sewage, industrial wastes, and storm water, and (2) related structures such as manholes and catch basins.

1.2 The property requirements of this standard apply at the time of purchase. The use of results from testing of brick extracted from masonry structures for determining conformance or non-conformance to the property requirements (Section 4) of this standard is beyond the scope of this standard.

1.3 Brick covered by this standard are manufactured from clay, shale, or similar naturally occurring substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment must develop sufficient fired bond between the particulate constituents to provide the strength and durability requirements of this specification. (See firing and fired bond in Terminology C1232.)

1.4 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.
