This specification covers joints for plastic pipe systems intended for drain, and gravity sewerage pipe at internal or external pressures less than a certain ft. head using flexible watertight elastomeric seals. The joints are classified into two types based on effecting watertightness through compression of an elastomeric seal or ring: push-on-joint is a joint in which an elastomeric ring gasket is compressed in the annular space between a bell end or socket and a spigot end of pipe and mechanical joint is a joint made using mechanical means or devices to develop a pressure seal. Joints shall not leak when subjected to the internal and external hydrostatic tests. All surfaces of the joint upon or against which the gasket bears shall be smooth and free of cracks, fractures, or imperfections. The gasket shall be the sole element depended upon to make the joint flexible and watertight. The gasket shall be a continuous elastomeric ring. In mechanical joints, the pipe spigot shall have a wall thickness sufficient to withstand, without deformation or collapse, the compressive force exerted when the fitting is tightened. Some joint designs provide for the angular deflection of a pipe joint, without reducing watertightness. Where greater deflections are required than permitted by the joint design, suitable fittings must be provided. The joint components shall be of such design that they will withstand the forces caused by the compression of the gasket when joined without cracking or fracturing when tested. Dimensions of joint components and gaskets shall meet the requirements specified. Test methods such as internal pressure test and vacuum test shall be performed.1.1 This specification covers joints for plastic pipe systems intended for drain, and gravity sewerage pipe at internal or external pressures less than 25-ft head using flexible watertight elastomeric seals. This specification is intended to cover the test requirements, test methods, and acceptable materials. The test methods described for the joints are not intended to be routine quality control tests but to be reliability or performance requirements.1.2 The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.1.3 The following safety hazards caveat pertains only to the test method portion, paragraph 7.5, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use.

This specification covers the minimum performance and material requirements for resilient connectors used for connections between precast reinforced concrete storm sewer structures and pipes, and between precast reinforced concrete pipe and laterals for storm drainage systems. These connectors are designed to prevent soil migration between the pipe and storm sewer structure, and between the pipe and lateral. Resilient materials for connectors, filler rings, and mechanical devices shall be tested, and shall conform to the specified values chemical resistance, tensile strength, elongation hardness, accelerated oven-aging, compression set, water absorption, ozone resistance, low-temperature brittle point, and tear resistance. The design of the connector and the pipe stubs are detailed.1.1 This specification covers the minimum performance and material requirements for resilient connectors used for connections between precast reinforced concrete storm sewer structures conforming to Specification C478/C478M and pipes, and between precast reinforced concrete pipe and laterals for storm drainage systems.1.1.1 These connectors are designed to prevent soil migration between the pipe and storm sewer structure, and between the pipe and lateral.1.2 The values stated in inch pound or SI units are to be regarded separately as standard. The SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.NOTE 1: This specification covers the design, material, and performance of the resilient connection only. Connections covered by this specification are adequate for hydrostatic pressures up to 6 psi (14 ft) [41 kPa (4.3 m)] without leakage when tested in accordance with Section 7. Infiltration quantities for an installed system are dependent upon many factors other than the connections between storm sewer structures and pipe, and allowable quantities must be covered by other specifications and suitable testing of the installed pipeline and system.NOTE 2: For installations that exceed 6 psi (14 ft) [41 kPa (4.3 m)], the user is cautioned to verify the amount of hydrostatic head pressure the connector will experience. If the total pressure applied to the connector exceeds the 6 psi [41 kPa] limits of the specification, the user is advised to contact the connector manufacturer for alternative methods of connecting the pipe, or applicable alternative standards.1.3 The following precautionary caveat pertains only to the test methods portion, Section 7, of this specification: 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.
