1.2 This specification covers pipe and fittings intended for normal residential and commercial uses and is not intended for use in
unusual corrosive conditions.

in normal use or temperatures approaching 140°F (60°C)140 °F (60 °C) may be encountered.

F714.
1.4 The interchangeability of pipe and fittings made by different manufacturers is not addressed in this specification. Transition
