ASTM C877-00

Standard Specification for External Sealing Bands for Concrete Pipe, Manholes, and Precast Box Sections

SCOPE
1.1 This specification covers external sealing bands to be used in conjunction with concrete pipe as defined in Terminology C 822 and conforming to Specifications C 14, C 76, C 412, C 478, C 506, C 507, C 655, C 985, C 1417, and C 1433.
1.1.1 Type I, Rubber and Mastic Bands.
1.1.2 Type II, Plastic Film and Mesh Reinforced Mastic Bands.
1.1.3 Type III, Chemically-Bonded Adhesive Butyl Bands.
1.2 A complete metric companion to Specification C 877 has been developed-C 877M; therefore, no metric equivalents are presented in this specification.
Note 1—This specification covers only the design and material of the sealing bands. Sealing bands covered by this specification are adequate, when properly installed, for external hydrostatic pressures up to 13 psi, (30 ft) without leakage. The amount of infiltration or exfiltration flow in an installed pipeline is dependent upon many factors other than the sealing bands; allowable quantities and suitable testing of the installed pipeline and system must be covered by other specifications.
