This specification covers the specification for the nonreinforced concrete pipe to be used for the conveyance of irrigation water with working pressures, including hydraulic transients, and for use in drainage. The design, joint, and concrete mixture of the pipe is detailed. The acceptability of the pipe shall be determined by the results of the tests prescribed in this specification, such as external load test, absorption test, and hydrostatic test.1.1 This specification covers nonreinforced concrete pipe to be used for the conveyance of irrigation water with working pressures, including hydraulic transients, as shown in Table 1 and for use in drainage.1.2 The values stated in either imperial or metric units are to be regarded separately as standard. Within the text the metric units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values may result in nonconformance with the specification.NOTE 1: This specification is for manufacturing and purchase only and does not include requirements for bedding, backfill, installation, or field repairs. The owner is cautioned that he must correlate field conditions with the characteristics of the pipe specified and provide inspection during installation.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.

1.1 This practice covers general and basic procedures related to the proper installation of thermoplastic, flexible, pressure piping, 36 in. nominal size and smaller, for underground irrigation systems. Because there is considerable variability in end-use requirements, soil conditions, and thermoplastic piping characteristics, it is the intent of this practice to outline general objectives and basics of proper installation and to provide pertinent references, rather than to prescribe detailed installation procedures. 1.2 This practice should not be used for installing thermoplastic underground sewer, drain, potable water, conduit or gas service piping. 1.3 The values stated in inch-pound units are to be regarded as the standard. Values in parentheses are given for information only. 1.4 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This practice establishes the basic design and proper installation procedures for flexible thermoplastic piping systems for underground irrigation systems that operate at maximum working pressures of 125 psi. The thermoplastic pipes shall be made of poly(vinyl chloride) (PVC) or polyethylene (PE), and shall be assembled to withstand the design working pressure for the pipeline without leakage, internal restriction, or obstruction that could reduce line capacity below design requirements. The piping system shall conform to requirements for the working pressure, service factor, system capacity, friction losses, flow velocity, outlets, check valves, pressure-relief valves, and air-release and vacuum-relief valves. The procedures for trench and joints preparation, thrust block construction, line charging, and backfilling are also detailed thoroughly.1.1 This practice establishes procedures for the design and installation of thermoplastic flexible piping systems, for underground irrigation systems. Because there is considerable variability in end-use requirements, soil conditions, and thermoplastic piping characteristics, the intent of this practice is to outline general objectives and basics of systems design, proper installation procedures, and to provide pertinent references.1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units which are for information only and are not considered standard.1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.

This specification covers classification criteria, nomenclature system, requirements, test methods, joints, fittings, certification, and marking for polyethylene (PE) thermoplastic high-pressure irrigation pipeline systems. PE materials for pipe are categorized by short-term and long-term strength tests. Materials shall meet the requirements of basic PE grades. Test methods for pipe shall include dimensions, tolerances, sustained pressure, burst pressure, carbon black content, density, and elevated temperature test. Joints and couplings shall withstand the design maximum working pressures. Plastic fittings shall meet all the dimensional and quality requirements.1.1 This specification covers polyethylene (PE) thermoplastic pipelines used to convey, at rated pressures of 80 to 200 psi, water that is to be used for irrigation purposes. This specification includes criteria for classifying the pipe materials, a system of nomenclature for plastic pipe, requirements for pipe, test methods, joints, fittings, certification, and marking.1.2 The values stated in inch-pound units are to be regarded as the standard.1.3 The following safety hazards caveat pertains only to the test method 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 and health practices and determine the applicability of regulatory limitations prior to use.

This specification covers reinforced concrete pipe with rubber gasket joints to be used for the conveyance of irrigation water with working pressures, including hydraulic transients. The acceptability of the pipe, joint design, and gaskets shall be determined by the results of the tests prescribed in this specification, if and when required, and by inspection to determine whether the pipe and gaskets conform to the specification as to design and freedom from defects. Pipe manufactured in accordance with this specification shall consist of concrete, cement, fly ash, ground granulated blast furnace slag, allowable combinations of cementitious materials, a combination of Portland cement, admixtures and blends, and aggregates. The rubber compound used in the manufacture of the gasket shall be compounded from natural rubber, synthetic rubber, or a mixture of the two fabricated as prescribed in the specification. The rubber from which the gaskets are fabricated shall have the following physical properties: ultimate elongation at break; ultimate elongation at break after aging; hardness; compression set; water absorption; and ozone resistance. If a splice is used in the manufacture of the gasket, the strength shall be such that the gasket shall withstand elongation over the part of the gasket that includes the splice with no visible separation of the splice. Test specimens shall have the following test requirements: number and type of tests; external load test requirement; and hydrostatic test requirement. Rubber gasket compound tests shall include the following: tensile strength; elongation; aging; hardness; compression set; water absorption; and ozone resistance.1.1 This specification covers nonreinforced concrete pipe with rubber gasket joints to be used for the conveyance of irrigation water with working pressures, including hydraulic transients, as shown in Table 1.1.2 A complete metric companion to Specification C505 has been developed—C505M; therefore, no SI equivalents are presented in this specification.NOTE 1: This specification is for manufacturing and purchase only and does not include requirements for bedding, backfill, installation, or field repairs. The owner is cautioned that he must correlate field conditions with the characteristics of the pipe specified and provide inspection during installation.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.
