1.1This specification covers external sealing bands to be used in conjunction with concrete pipe as defined in Terminology C822 and conforming to Specifications C14M, C76M, C412M, C478/C478M, C506M, C507M, C655M, C985M, C1417M, and C1433M.
1.1.1Type I, Rubber and Mastic Bands.
1.1.2Type II, Plastic Film and Mesh Reinforced Mastic Bands.
1.1.3Type III, Chemically Bonded Adhesive Butyl Bands.
1.2This specification is the metric counterpart of Specification C877.
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 90 kPa, (9.14 m) 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.
1.3This 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.
