CSA A257 SERIES-09

Standards for concrete pipe and manhole sections - Fifth Edition; Update No. 1: October 2010

Organization:
CSA - CSA Group
Year: 2009

Abstract: This Standard applies to circular precast concrete pipe, manhole (maintenance hole) sections, and accessories intended for
(a) use as sewer pipe for the conveyance of sewage, industrial wastes, and storm water; and
(b) the construction of culverts.
This Standard describes the following procedures for testing circular precast concrete pipe, manhole sections, and joints:
(a) three-edge-bearing test (see Clause 4);
(b) concrete compression tests (see Clause 5);
(c) absorption test (see Clause 6);
(d) hydrostatic test (see Clause 7);
(e) flat slab top test (see Clause 8); and
(f) manhole step tests (see Clause 9).
This Standard does not apply to cast-in-place elements or to non-circular precast concrete pipe, manhole, or catch basin sections.
In CSA Standards, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" is used to express possibility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
