Test pressure levels for establishing hydrostatic design basis
shall be calculated on pipe minimum wall dimensions.
5.2.1 Joint designs shall require retesting under this section
only if the joint design is changed or if the pipe compound is
altered in any manner that produces a lower hydrostatic design

previous validation testing of the joint design.
5.3 Mechanical Joint—The mechanical joint shall provide a
pressure rating equal to or greater than that of the correspond-
ing pipe.
5.3.1 Internal Stiffener—The pipe spigot shall have a wall
thickness sufficient to withstand, without deformation or col-
lapse, the compressive force exerted when the fitting is
tightened. If the wall is not sufficient to withstand the com-
pressive force, then a
