Scope of standard

This specification covers flexible watertight joints for
concrete pipe and precast manhole sections, using rubber gaskets
for sealing the joints, where infiltration or exfiltration is a
factor in the design. The specification covers the design of joints
and the requirements for rubber gaskets to be used therewith, for
pipe conforming in all other respects to Specification C 14,
Specification C 76, or Specification C 507 and precast manhole
section conforming in all other respects to Specification C 478,
provided that if there is conflict in permissible variations in
dimensions the requirements of this specification for joints shall
govern.

A complete metric companion to Specification C 443 has been
developed-C 443M; therefore, no metric equivalents are presented in
this specification.

NOTE I-This specification covers the design and performance of
the rubber gasket joint only. Joints covered by this specification
are normally adequate for hydrostatic pressures up to 13 psi (30
ft) without leakage, when tested in accordance with Section 9.
Infiltration or exfiltration quantities for an installed pipeline
are dependent upon many factors other than the joints, and
allowable quantities must be covered by other specifications and
suitable testing of the installed pipeline and system.
