This Standard covers polyethylene (PE) pipe, tubing, and fittings for use in potable cold water supply services or other applications such as water-based ground source geothermal systems.
This Standard specifies requirements for materials, quality of work, dimensions, sustained pressure, environmental stress cracking, and markings.
In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
