Additional Comments: W/D NO S/S
Published By:ASTM International (ASTM)
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.
This practice should not be used for installing thermoplastic underground sewer, drain, potable water, conduit, or gas service piping.
