ASTM C32

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.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

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.

1.1.1 Sewer Brick:

1.1.1.1 Grade SS—Brick intended for use in structures requiring low absorption and resistance to the action of sewage carrying large quantities of abrasive material at velocities exceeding 8 ft (2.4 m)/s.

1.1.1.2 Grade SM—Brick intended for use in structures requiring resistance to the action of sewage carrying abrasive materials at velocities less than 8 ft (2.4 m)/s.

1.1.2 Manhole Brick:

1.1.2.1 Grade MS—Brick intended for use in manholes and catch basins not requiring high degrees of abrasive resistance but where a high and uniform degree of resistance to frost action and disintegration is needed when the brick may be frozen when permeated with water.

1.1.2.2 Grade MM—Brick intended for use in manholes not requiring high degrees of abrasive resistance but where a moderate and nonuniform degree of resistance to frost action and disintegration is needed when the brick may be permeated with water.

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 3) 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 C 1232.)

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.
