Full Description
This Standard establishes the minimum physical and performance requirements for plastic piping system
components. These criteria were established for the protection of property, public health and the
environment.
The physical and performance requirements in this standard apply to plastic piping system components as
well as non-plastic components of the ground loop heat exchanger including but not limited to cross-linked
polyethylene (PEX) pipes and fittings used in water-based ground-source heat pump systems. This
standard does not cover refrigerant based ground loop heat exchangers such as direct expansion (DX)
systems. This Standard does not cover hydronic heating or cooling systems within buildings.
