(Specification)Standard Specification for Joints for Concrete Pipe and Manholes, Using Rubber Gaskets (Metric)
Standard Specification for Joints for Concrete Pipe and Manholes, Using Rubber Gaskets (Metric)
ABSTRACT
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 numerical values in this specification are not presented in inch-pound units, but rather, in metric or SI units only. All rubber gaskets shall meet the dimensions, tolerances, and physical requirements of both standard gasket and oil resistant gasket requirements. Assembled joints should pass the following performance test without leakage at the joints: pipes in straight alignment, and pipes in maximum deflected position.
SCOPE
1.1 This specification covers flexible leak-resistant 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 C14M, Specification C76M, or Specification C507M and precast manhole section conforming in all other respects to Specification C478M, provided that if there is conflict in permissible variations in dimensions, the requirements of this specification for joints shall govern.
1.2 This specification is the metric counterpart of Specification C443.
Note 1: This specification covers the design and performance of the rubber gasket joint only. Joints covered by this specification are adequate for hydrostatic pressures up to 90 kPa (9 m), when tested per 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.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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
