CSA A257 SERIES-14 (R2019)

This is the sixth edition of CSA A257 Series, Standards for concrete pipe and manhole sections. It supersedes the previous editions published in 2009, 2003, 1992, 1982, and 1974. This is a performance Standard. As with the previous editions, the Standards contained in this edition include requirements for:
(a) the determination of physical properties;
(b) non-reinforced circular concrete pipe;
(c) steel-reinforced circular concrete pipe; and
(d) joints for concrete pipe.

The major change in this new edition is the clarification that this is a performance Standard. CSA acknowledges that the development of these Standards was made possible, in part, by the financial support of the Canadian concrete pipe and manhole producers.

This series contains the following standards:

• A257.0-14 - Methods for determining physical properties of circular precast concrete pipe, manhole sections, catch basins, and fittings
• A257.1-14 - Non-reinforced circular concrete culvert, storm drain, sewer pipe, and fittings
• A257.3-14 - Joints for circular concrete sewer and culvert pipe, manhole sections, and fittings using rubber gaskets
• A257.4-14 - Precast reinforced circular concrete manhole sections, catch basins, and fittings
