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. 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.1.4 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.
