This specification deals with the metric standard for three types of external sealing bands to be used in conjunction with concrete pipe, manholes, and precast box sections. The first type of bands shall be composed of rubber, mastic, and protective film elements, while the second type shall consist of a plastic film, reinforced, rubberized, asphalt, mastic coating with steel straps. The third type shall be composed of a backing band, an applied continuous butyl adhesive coating and an optional release element. All the elements of each type of sealing band shall have physical properties conforming with specified limits as determined through appropriate test methods herein provided.1.1 This 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.1.1.1 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 This 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.1.3 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 specification covers nonreinforced concrete pipe designed for specified strengths and intended to be used for the conveyance of sewage, industrial wastes, and storm water and for the construction of culverts. Strength test and load test shall be made in accordance with the specified requirements.1.1 This specification covers nonreinforced concrete pipe designed for specified strengths and intended to be used for the conveyance of sewage, industrial wastes, and storm water and for the construction of culverts.1.2 This specification is the metric counterpart of Specification C985.NOTE 1: This specification is a manufacturing and purchase specification only and does not include requirements for bedding, backfill, or the relationship between field load conditions and the designated strength of the pipe. However, experience has shown that the successful performance of this product depends upon the proper selection of the pipe strength, type of bedding and backfill, and care that the installation conforms to the construction specifications. The owner of the concrete pipe specified herein is cautioned that he must correlate the field requirements with the pipe strength specified and provide inspection at the construction site.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.

5.1 This is a quality test control performed at the manufacturing plant to establish that the finished, shippable pipe meets the leakage limits stated in the specifications.1.1 This test method covers procedures for testing of precast concrete pipe sections, prior to delivery, where maximum field leakage rates are specified.1.2 Tests described in this standard are intended to be used at the point of manufacture of the concrete pipe and are not intended for testing installed pipe (for field tests see Practices C969 and C1214). The user of this specification is advised that individual or multiple pipe sections may be tested for the purpose of testing the pipe barrel and additionally the joints in straight alignment when multiple pipe sections are tested.1.3 Test times are based on leakage rates and therefore are proportional only to the pipe diameter and are constant for any length of test pipe or pipeline.1.4 Test times tabulated and the rate of air loss in this standard are based on successful testing of installed pipelines. However, since air and water have different physical properties, retests of some pipelines not meeting field air tests have been successful when tested with water. The leakage rates of 0.0017 CFM/ft2 and 0.0003 CFM/ft2, were determined empirically as the maximums for pipe to meet the 50 and 200 gal/(in. of internal diameter) (mile of sewer) (24h) test rates, respectively1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.NOTE 1: The availability of this test procedure for concrete pipe varies from location to location. Check with local supplier(s) for availability and recommendations.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. See Section 6 for specific safety precautions.1.7 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 specification covers reinforced arch-shaped concrete pipe to be used for the conveyance of sewage, industrial wastes, storm water, and for the construction of culverts. Pipe manufactured according to this specification shall be of three classes identified as Class A-II, A-III, and A-IV. The reinforced concrete shall consist of cementitious materials, mineral aggregates, and water, in which steel has been embedded in such a manner that the steel and concrete act together. The pipe shall be designed to meet both the 0.01 in. crack and ultimate strength requirements determined by conducting plant load bearing tests, material tests, and inspection of manufactured pipe for visual defects and imperfections. The reinforcement, joint, and manufacture are detailed.1.1 This specification covers reinforced arch-shaped concrete pipe to be used for the conveyance of sewage, industrial wastes, storm water, and for the construction of culverts.1.2 This specification is the SI companion to Specification C506; therefore, no inch-pound equivalents are presented in this specification. Reinforced concrete pipe that conform to the requirements of Specification C506 are acceptable under this Specification C506M unless prohibited by the owner.NOTE 1: This specification is a manufacturing and purchase specification only, and does not include requirements for bedding, backfill, or the relationship between field load condition and the strength classification of pipe. However, experience has shown that the successful performance of this product depends upon the proper selection of the class of pipe, type of bedding and backfill, and care that the installation conforms to the construction specifications. The owner of the reinforced concrete pipe specified herein is cautioned that he must correlate the field requirements with the class of pipe specified and provide inspection at the construction site.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.
