1.1 This guide is intended for use in the selection, design, and installation of thermoplastic water-pressure piping systems. For specific projects, a thorough review of this guide is recommended for the purpose of selecting specific materials, methods of joining, system design factor, and any special procedures deemed necessary to assure a satisfactory system. Note 1: Comprehensive information on the selection, design, joining, system design factors, installation and special products and piping systems for pressurized water and other specialized applications is available in the Uni-Bell PVC Pipe Association Handbook of PVC Pipe Design and Construction, PPI Handbook of Polyethylene Pipe and from other domestic and International sources such as PE compound and product manufacturers and trade associations. 1.2 It is recommended that governing codes and project specifications be consulted prior to the use of this guide. Nothing in this guide should be construed as recommending practices or systems at variance with governing codes and project specifications. 1.3 The pipe, fittings, and joining materials shall meet the requirements of one or more of the following component product standards listed in 1.3.1 through 1.3.4 to the extent applicable. In 1.3.1 , 1.3.2 , and 1.3.4 the pipe standards followed by ( a ) are outside diameter-controlled pipes. 1.3.1 For poly(vinyl chloride) (PVC) plastic piping components: Title of Specification ASTM Designation Poly(Vinyl Chloride) (PVC) Plastic Pipe, Schedules 40, 80 and 120 ( a ) D1785 Poly(Vinyl Chloride) (PVC) Plastic Pipe (SDR-PR) ( a ) D2241 Threaded Poly(Vinyl Chloride) (PVC) Plastic Pipe Fittings, Schedule 80 D2464 Poly(Vinyl Chloride) (PVC) Plastic Pipe Fittings, Schedule 40 D2466 Socket-Type Poly(Vinyl Chloride) (PVC) Plastic Pipe Fittings, Schedule 80 D2467 Solvent Cements for Poly(Vinyl Chloride) (PVC) Plastic Pipe and Fittings D2564 Bell-End Poly(Vinyl Chloride) (PVC) Pipe ( a ) D2672 Poly(Vinyl Chloride) (PVC) Plastic Tubing ( a ) D2740 Socket-Type Poly(Vinyl Chloride) (PVC) Plastic Line Couplings D3036 Joints for Plastic Pressure Pipes Using Flexible Elastomeric Seals D3139 Elastomeric Seals (Gaskets) for Joining Plastic Pipe F477 PVC and ABS Injected Solvent Cemented Plastic Pipe Joints F545 1.3.2 For Chlorinated Poly(Vinyl chloride) (CPVC) plastic piping components: Title of Specification ASTM Designation Chlorinated Poly(Vinyl chloride) (CPVC) Plastic Pipe, Schedules 40 and 80 (a) F441/F441M Chlorinated Poly(Vinyl chloride) (CPVC) Plastic Pipe Fittings, Schedule 80 F439 Solvent Cements for Chlorinated Poly(Vinyl chloride) (CPVC) Plastic Pipe and Fittings F493 1.3.3 Standards for polyethylene (PE) plastic piping: ASTM Standard Designation Standard Specification for Polyethylene (PE) Plastic Pipe (SIDR-PR) Based on Controlled Inside Diameter D2239 Standard Specification for Plastic Insert Fittings for Polyethylene (PE) Plastic Pipe D2609 Standard Specification for Socket-Type Polyethylene Fittings for Outside Diameter-Controlled Polyethylene Pipe and Tubing D2683 Standard Specification for Polyethylene (PE) Plastic Tubing D2737 Standard Practice for Underground Installation of Thermoplastic Pressure Piping D2774 Standard Specification for Butt Heat Fusion Polyethylene (PE) Plastic Fittings for Polyethylene (PE) Plastic Pipe and Tubing D3261 Standard Specification for Polyethylene (PE) Plastic Pipe (DR-PR) Based on Controlled Outside Diameter D3035 Standard Specification for Polyethylene (PE) Plastic Pipe (DR-PR) Based on Outside Diameter F714 Standard Specification for Electrofusion Type Polyethylene Fittings for Outside Diameter Controlled Polyethylene and Crosslinked Polyethylene (PEX) Pipe and Tubing F1055 Standard Specification for Socket Fusion Tools for Use in Socket Fusion Joining Polyethylene Pipe or Tubing and Fittings F1056 Standard Practice for Electrofusion Joining Polyolefin Pipe and Fittings F1290 Standard Specification for Deformed Polyethylene (PE) Liner F1533 Standard Guide for Construction Procedures for Buried Plastic Pipe ...
