ASTM A74-13a

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Cast Iron Soil Pipe and Fittings
This standard is issued under the fixed designation A74; 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 (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
1. Scope
1.1 This specification covers cast iron soil pipe and fittings for use in gravity flow plumbing, drain, waste and vent sanitary, and
storm water applications. It establishes standards covering material, manufacture, mechanical and chemical properties, coating, test
methods, inspection, certification, product markings, dimensions, and dimensional tolerances for extra heavy and service cast iron
soil pipe and fittings. These pipe and fittings are not intended for pressure applications as the selection of the proper size for
sanitary drain, waste, vent, and storm drain systems allows free air space for gravity drainage.
1.2 This specification covers pipe and fittings of the following patterns and, when so designated, shall apply to any other patterns
that conform with the applicable requirements given in this specification.
